iOS and Android apps, from first sketch to App Store
The apps that succeed launch small and learn fast. We help you decide what the first version really needs, test it as a clickable prototype with real users, then build it for iPhone and Android with the backend, admin tools and analytics to keep improving it.

(The problem)
Most apps fail because version one tries to do too much
Big feature lists mean long builds, big budgets and a launch that arrives late. By then the assumptions behind half the features have often turned out to be wrong.
A focused first version, tested as a prototype with real users, gets to market faster, costs less and tells you what to build next.
What's included
Ship a focused first version, then grow it.
- 01
Cross-platform or native
React Native and Flutter for most apps; Swift and Kotlin when device features demand it.
- 02
Product design
User flows, prototypes and interface design tested before development.
- 03
Backend and admin
Accounts, payments, notifications, APIs and a dashboard for your team.
- 04
Store submission
App Store and Google Play listings, review and release management.
- 05
Analytics
Events and funnels set up so you know where users drop off.
- 06
Ongoing support
OS updates, fixes and new features after launch.
How it works
- 01
Scope
Core user journeys, what's in version one and what waits, plus the backend and integrations needed.
- 02
Prototype
A clickable prototype you test on your own phone, and with customers, before code is written.
- 03
Build
App, backend and admin panel built in weekly releases you can install and try.
- 04
Launch
Store listings, submission and review handled, then crash monitoring and a post-launch plan.
Native vs Cross-Platform: the decision our mobile app development agency makes with you before writing a line of code
Native (Swift / Kotlin)
- Best-in-class performance and frame rates (60fps guaranteed)
- Full access to platform APIs, camera, AR, biometrics, background processing
- Aligns with Apple Human Interface Guidelines and Material Design precisely
- Lower long-term maintenance overhead as OS updates are handled natively
- Required for apps with complex animations, real-time data, or hardware integration
Best for High-complexity apps, fintech, health, fitness wearables, or anything where UX precision is the core product differentiator
Cross-platform (React Native / Flutter)
- Single codebase targeting iOS and Android simultaneously, 30–40% lower build cost
- Faster go-to-market for MVPs and early-stage validation
- Shared business logic, API calls, and state management between platforms
- Strong performance for most app categories outside of high-frame-rate or hardware-intensive use cases
- React Native used by Meta, Shopify, and Coinbase, production-proven at scale
Best for B2B tools, internal apps, marketplaces, booking platforms, or any app where shipping quickly on both platforms is the primary requirement

We had two failed app builds from previous agencies before finding Tecklogist. The difference was obvious from the first call, they asked the right questions before writing any code.

Good questions
Last reviewed October 2026
How much does an app cost to build?+
A focused cross-platform MVP costs far less than a feature-heavy app with complex integrations. After scoping we send a fixed price for version one and an estimate for what might follow.
React Native, Flutter or native?+
Cross-platform suits most business apps and saves money. Native is worth it for heavy device features, complex animation or demanding real-time performance. We'll recommend one for your specific app.
How long does it take?+
Most MVPs take six to twelve weeks from approved prototype to store submission. Apple's review usually adds a few days.
Who owns the app?+
You do: the code repository, the Apple and Google developer accounts and all designs are registered to your company.
Can you take over an existing app?+
Yes. We review the codebase first and tell you honestly whether to continue with it or rebuild.
What happens after launch?+
Apps need updates as iOS and Android change. We offer a monthly support plan, or a clean handover to your own team.
