How to Build a Super App: 2026 Guide

It’s 2026, and everyone is building super apps. Examples such as WeChat, Careem, and STC Pay are frequently referenced as super app archetypes. From a business perspective, what defines these platforms is not the number of features they offer, but their ability to connect supply and demand within a single ecosystem. This dynamic is explored in more detail in the Business Reality of Uniting Your Apps into One Super App. But things get a lot more interesting in the fintech world.

What is a Super App?

A super app is a multi-functional platform that integrates various services and features into a single application.

When fintech teams explore how to build a super app, they often encounter definitions rooted in consumer lifestyle platforms. These descriptions typically frame super apps as “everything apps” that combine messaging, food delivery, transportation, and commerce into one interface. However, in fintech, super apps are not lifestyle hubs. They are modular financial ecosystems that unify wallets, payments, cards, compliance, rewards, and partner services inside one orchestrated product experience.

A fintech super application grows horizontally through shared financial infrastructure, unified identity, and modular design. It does not grow by stacking unrelated features. This distinction is fundamental when deciding how to build a super app that can scale, remain compliant, and evolve. 

Why Super Apps Are Emerging in Fintech

The rise of fintech super apps is driven by structural shifts in how financial services are built, distributed, and consumed. User demand for convenience plays a role, but the primary drivers are infrastructure maturity, regulatory evolution, and platform economics.

One of the strongest driving factors behind this shift is embedded finance. Payments, wallets, lending, and accounts are increasingly delivered directly inside digital products, rather than through standalone banking interfaces. This transition, from banks as destinations to platforms as financial entry points, is examined in detail in Embedded Finance vs. Traditional Distribution of Financial Services.

Key drivers accelerating super app development in fintech:

• Growing demand for embedded finance and in-context payments
• Customer preference for a single financial hub instead of fragmented applications
• Banks competing with neobanks on user experience, speed, and engagement
• Cost efficiency is achieved by operating one platform rather than multiple products
• Partner ecosystems replacing in-house licensing and lengthy integration cycles

Regulation and platform maturity play a decisive role. Regions such as MENA and parts of Europe benefit from faster regulatory evolution, open banking initiatives, and fewer legacy constraints. The United States market remains more fragmented due to state-level compliance complexity, which slows the emergence of large-scale payments super apps.

As a result, MENA is emerging as a natural testbed for fintech super applications, particularly for SME-focused platforms that unify wallets, payments, and rewards under a single product surface.

Pros and Cons of Super Apps

Pros of super apps:

• Enhanced user convenience. Having multiple services, which complement each other or are related, in one app makes an app a one-stop shop for users. To many, it’s convenient. 
• Increased user retention. If a super app succeeds in making users utilize one of its functions, there is a chance that, over time, users will start using other features available. Eventually, users may abandon many smaller-scale apps and, by and large, stick with only a handful of super apps. 
• Cross-promotion opportunities among integrated services. Having an established user base makes it easier to promote additional services. When all such services are integrated within a single app, it makes promotion even more effective. An easy example is Instagram promoting Threads, which made Threads, a not-that-unique social platform, the fastest-growing app in history. 
• Cost efficiency by leveraging shared infrastructure and resources. The development of a super app is no less expensive than creating two apps. However, having a uniform infrastructure, team, and operational processes results in cost savings over time. 
• Higher revenue potential through diversified monetization channels. At the end of the day, revenue is a priority for most businesses. When a super app manages to keep its users active with a particularly successful offering, the potential for selling new products and services can grow nearly endlessly. 

Cons of super apps:

• Communicating the need for such an app to users may be difficult. Some target audiences, like elders using fitness apps, are resistant to change. Making them use a single unfamiliar app instead of one or two applications they got used to may cause rejection. 
• User overload due to the abundance of features. Super apps are always about having at least twofold the scope of features users had previously. That makes user onboarding and intuitive UI/UX critical points since the failure to accommodate users with the super app would lead, once again, to rejection.
• Managing customer support becomes more complex. Developing a super app out of several traditional apps leads to merging the support base. While having two support centers is a possible temporary solution, later on, a business will have to merge customer support. Such a change is challenging from an organizational perspective. 
• Risk of losing users during the transition. In light of the already mentioned risks, some losses of existing users are expected from transitioning from an older app to a new super app. Probably, the loss of 10-15% of the user base is not critical, yet the risks of losing as much as half of the users are real.  
• Increased complexity in maintaining and updating the app. Due to the complexity and the scale of the super app, it’s expensive and difficult to maintain. While maintaining a traditional app can cost 10-20% of the initial development cost, maintaining a super app may be even higher, especially for the first year or two after the release. 

A super app strategy succeeds only when architecture, sequencing, and regulatory ownership are addressed deliberately. 

How to Build a Super App: Specialized Development Phases

Modular Super App Architecture

A scalable super app architecture must be modular. Monolithic systems lack the flexibility required for horizontal expansion and partner integration. Modular and microservices-based architectures allow fintech teams to introduce new capabilities, such as wallets, rewards, lending, or third-party services, without destabilizing existing functionality.

This architectural choice becomes especially important when the super app is built around a digital wallet. Wallets often serve as the entry point into broader financial ecosystems. For a deeper breakdown of wallet-first platform design, see How to Create a Digital Wallet: Step-by-Step Guide.

Super App Design Systems

Super app design is not limited to visual consistency. A unified design system enables teams to expand product functionality without fragmenting the user experience. In fintech super apps, design systems act as scalability mechanisms that support trust, clarity, and usability as new financial services are introduced.

Merging Existing Applications

Super app development frequently follows a brownfield approach, where multiple existing products are unified into one orchestrated platform. There are two primary paths: reworking one application into the architectural foundation or building a new modular platform and migrating services gradually.

DashDevs’ experience delivering multi-service platforms shows that success depends less on visual consolidation and more on backend orchestration. Identity, payments, pricing, and service logic must be aligned without breaking existing user flows. The same principle applies directly to fintech super applications.

How to merge existing apps

Much like with the merge and unification of the UI/UX design system, we have difficulties with the architecture of a super app. It’s usually incredibly centered around a certain way an app works. Changing it to something completely different and naturally more complex can cause issues and errors. Here are two options for how to approach the merging of apps:

1. Rework the architecture of one app and make it the basis for a super app. This way, both apps should be prepared from the perspective of how they look, feel, and operate. Then, one can be integrated on top of another. 
2. Create a super app architecture from scratch. Here, we should prepare a completely new modular architecture system. Then, it’s necessary to add functionalities from apps we intend to merge on top of this newly created architecture. Lots of rework and redevelopment are expected here. 

As we make sure not to pigeon-hole ourselves, we take pride in the taxi and express delivery super app success story. As opposed to the UX challenge many super apps face, this one posed the backend orchestration challenge. The process involved aligning identity, payments, routing, pricing and service logic across multiple products, all while maintaining existing user flows. Our main contribution went toward solution architecture, backend unification, and mobile app consolidation, directing the app towards a singular ecosystem rather than fragmented services.

The same logic applies to fintech apps; ones that we approach with the “ecosystem first, apps second"mentality. As a result, we develop fintech apps with wallets, crypto, payments, rewards and partner services, all within one platform.

Unified Authorization and Onboarding Flow

A fintech super app requires a single identity layer. Users authenticate once and gain access to multiple services through a unified onboarding process. This flow must accommodate KYC, permissions, and regulatory requirements while introducing users to a broader financial ecosystem rather than a single feature.

The choice between them depends on the type of application. Monolithic architecture is rigid. It has little room for scaling and adding functionalities, and therefore presents a bad pick for super apps. At the same time, with a modular architecture, development requires more time and effort. However, scaling and updating become much easier.

You can discover more details on modular architecture in development, including usage intricacies and real-life applications in another one of our blog posts. 

In the majority of cases, super apps are either fully modular architecture-based apps or apps created when shifting from a monolithic to a modular architecture. So, the big idea here is simple. Stick to modular architecture if you’re looking for superapp development. 

Dedicated Design System 

As mentioned, super apps often present a mix of two or even more already existing applications, each with its own design. Often, the design doesn’t comply with a particular brand book. It also may differ because of the app platform chosen, e.g., iOS or Android. The only way to combat this issue is to create a desiccated design system.

A dedicated design system is a set of standardized design guidelines, reusable components, and visual elements that ensure consistency across all interfaces and platforms within an application or product ecosystem.

Here you have two options on how to approach the creation of a dedicated design system:

1. Incorporate the UI/UX design system from one existing application. Then you just apply it universally across all super app modules, adding more elements as per the existing brandbook.
2. Create a UI/UX design system from scratch. Here, you basically create a completely new design system, which will serve as a guide for creating all the custom elements for a super app. 

The choice is strictly a business decision. Usually, one or another technical constraints don’t significantly impact decision-making here.

Unification of authorization and onboarding flow

Separate apps, even ones belonging to the same company, have different authorization and onboarding flows. At the same time, when merging two apps, they should become one. For this, we again may choose either the unification route or the developing from scratch route. Anyway, we should achieve the following:

• Super app authorization should be uniform and usable for users of both legacy applications. Ideally, users authorized in one app should be able to login into super app with their existing login and password details.
• User databases should be united. However, user permission is required for this to happen legally. 
• The new onboarding flow should be able to introduce a product of a higher level of complexity. Usually, it’s created from scratch regardless of the development approach.

That’s all for the new super app development phases. Aside from the necessity to merge apps in one way or another and some restrictions imposed on the choice of architecture pattern, super app development is technically no different from building regular software. 

Super App Case Studies

Here are several examples of different, real-world fintech super apps:

Eleven

Eleven is a perfect demonstration of a wallet-first approach to building a fintech super application. Rather than positioning the product as a standalone crypto tool, Eleven was designed as a secure digital wallet combined with messaging, identity, and transaction capabilities inside a single financial surface. Users can hold and transfer crypto assets as easily as sending a message, which lowers friction and increases transaction frequency. This design makes the wallet the primary entry point into the ecosystem, not an isolated feature.

From a super app architecture perspective, Eleven illustrates how modular financial services can be layered without compromising security or usability. Custody, transactions, communication, and identity are orchestrated through a shared backend, enabling future expansion into payments, rewards, or additional financial services without redesigning the core product. This pattern reflects a common super app strategy in fintech, where the wallet acts as the foundation for horizontal ecosystem growth.

iOL Pay

iOL Pay platform represents a vertical super app model built around payments in the hospitality industry. Instead of targeting consumers directly, iOL Pay focuses on merchants and travel providers, unifying payment acceptance, multi-currency processing, and operational tooling into a single financial layer. Payments serve as the anchor service, embedded directly into booking and checkout flows across hotels and travel platforms.

As the platform scales, this payment-first foundation enables the addition of adjacent services such as loyalty logic, FX management, analytics, and wallet-based settlement, all without fragmenting the product experience. From a super app development standpoint, iOL Pay shows how industry-specific ecosystems can evolve into super applications by prioritizing orchestration and extensibility over feature breadth.

PayTile

PayTile is a wallet that illustrates how payments and rewards combine to form the engagement core of fintech super apps. PayTile allows users to send money privately, interact with nearby merchants through geolocation, and receive reward drops that are credited directly to their wallet balance. This approach turns the wallet into a daily-use financial tool rather than a passive payment utility.

From an ecosystem perspective, PayTile shows how rewards function as a retention engine while payments remain the transaction engine. The platform was built with a modular architecture that supports future service expansion, including merchant tooling, loyalty extensions, and additional financial products. This design reflects a broader super app pattern, where engagement and monetization are driven by tightly integrated financial and non-financial services operating on a shared platform.

Technical and Business Challenges in Developing a Super App

I’ve been repeatedly mentioning that super app development is a complex initiative. Aside from regular development challenges, it presents a suite of specific difficulties to address. Here I gathered them all, based on my experience with such projects:

• Unifying user flow and data models. Services within a super app often come from different domains, which necessitates alignment in workflows and data structures. For example, combining e-commerce, messaging, and payments means integrating user profiles across these services. Misaligned flows can lead to errors, such as inconsistent user data or failed transactions. 
• Creating a simplified and intuitive UI/UX design. A super app hosts numerous features. That’s why Poor design could overwhelm users and lead to high user churn. For example, a cluttered homepage with multiple unrelated options can confuse users. 
  • Explore how to create a user-friendly UI/UX design in another blog post by DashDevs.
• Implementing a consistent design system in code. When combining several apps, developers and designers are usually stuck with buttons, icons, and other elements that look and feel different. Fixing that, from a technical perspective, requires a unified design library implemented in the app’s codebase.
• Coordinating the development across multiple development teams. Super apps are typically developed by multiple teams working on independent modules. In such a scenario, miscommunication can cause integration delays or misaligned features. 
• Choose a proper module architecture and achieve seamless integration. A super app’s architecture is typically modular, created by usign dedicated framework of the customer and the tech team’s choosing. Making a perfect choice of tech stack is already difficult. At the same time, making sure all of the modules, as well as many integration super apps, work consistently and error-free is even more challenging.
• Ensure correct implementation of push notifications. Poor implementation of notifications leads to spam or irrelevant alerts. For instance, a payment reminder meant for one service showing up for another creates confusion. In the case of super apps, granular notification rules are used.
• Accurate handling of DeepLinks. DeepLinks allows users to navigate directly to specific app sections. Incorrect handling can result in broken links or users landing on irrelevant pages. For instance, a promotional link for an e-commerce deal should open the exact product page, not the generic homepage. This aspect is deeply related to the logic of how the app actually works. This matter is challenging, in the first place, from a UI/UX design perspective. 

When a Super App Strategy Makes Sense (and When It Doesn’t)

A super app strategy makes sense when a company controls a high-frequency financial use case. Products built around wallets, payments, or rewards generate regular user interaction, which creates the engagement and data foundation needed for ecosystem expansion. Without consistent usage, additional services struggle to gain adoption and add complexity without delivering value.

Ownership of the orchestration layer is equally important. Super apps rely on coordinated identity, transactions, data flows, and partner integrations. When a product depends too heavily on third-party SaaS without orchestration control, its ability to evolve is limited, and regulatory responsibility becomes harder to manage as the platform scales.

A super app approach works best when there is a clear plan for ecosystem growth. New services should be introduced gradually and reinforce the core financial use case rather than distract from it. Super apps often fail when too many services are launched too early, regulatory ownership is unclear, or new functionality is added to a monolithic core. For this reason, a super app should be treated as a platform decision rooted in architecture and operating model, not as a feature roadmap.

Final Take

There’s a stark difference between fintech super apps and those concerned with lifestyle. While equally complex, fintech super apps focus on enhancing existing functionality for a customer before considering adding more services and/or revenue streams. And while super apps are great, it doesn’t mean every business needs them. A high degree of strategizing and design is crucial to the success of any super app.

From UI/UX design to merging existing apps, all the way to taking a holistic approach to designing a super app, fintechs are urged to approach super apps with careful decision-making, preferably one that is customer-centric.
