Mobile App Development Agency for iOS and Android
A mobile app is a serious investment. Tkist mobile app development services handle the full lifecycle, from discovery and UX design through to App Store submission and post-launch monitoring. Our agency keeps design and development under the same roof so nothing is lost in handoff and every detail ships the way it was intended.

The Problem
Why 81% of apps fail within 90 days, and how to build one that does not
Most apps fail within weeks of launch, not because the idea was wrong, but because the experience was built around assumptions instead of real user behavior. Poor onboarding, sluggish performance, and missing native platform conventions kill retention. We have rebuilt apps after other agencies shipped them and seen the same structural mistakes every time.
Building an app is not the hard part. Getting people to open it every day for twelve months is. We design retention into every app from the first wireframe, not as an afterthought once download figures disappoint.

How We Work
From first call to measurable results
Discovery & UX
We map your user flows, define core features, and produce interactive design prototypes before any code is written.
Architecture & API
We design the backend architecture, define API contracts, and set up the development environment with CI/CD pipelines.
Build & Test
We build in two-week sprints with demos at each milestone. QA testing covers 50+ device/OS combinations.
Launch & Monitor
We handle App Store and Google Play submission, write ASO copy, and monitor crash rates and user retention for 60 days post-launch.
Platform Selection Guide
Native vs Cross-Platform: the decision our mobile app development agency makes with you before writing a line of code
We advise on this in the free discovery call, but here is how our mobile app development agency thinks about the decision before writing a line of code.
Best for: High-complexity apps, fintech, health, fitness wearables, or anything where UX precision is the core product differentiator
- 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: B2B tools, internal apps, marketplaces, booking platforms, or any app where shipping quickly on both platforms is the primary requirement
- 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
The Conversion Gap
Five things that kill app retention within 90 days, and how we design against each one
81%
of apps are abandoned within 90 days of first download
An app is not a product until it is opened for the second, third, and thirtieth time. Retention design starts at the first wireframe, not as an afterthought once download numbers disappoint. We design onboarding flows, habit-forming mechanics, and notification strategy before a line of code is written.
53%
of users uninstall apps citing a poor or confusing onboarding experience
The first three minutes determine whether a user ever returns. We run structured onboarding design workshops for every app we build, mapping the minimum path to first value, the exact moment a new user understands why the app is worth keeping.
4.4+
App Store rating required to sustain downloads, below which installs drop 70%
The App Store algorithm prioritizes apps with high ratings and consistent positive reviews. We build review request mechanics into every app, triggered after a positive in-app action, not after a frustrating one. Most of our apps launch with a structured review strategy already built in.
60%
reduction in crash rate with proper QA across 50+ real device configurations
The App Store has over 40,000 active device and OS combinations in the wild. We QA across 50+ real-device combinations before every submission, not just the simulator. Crash rates under 0.5% from day one are consistently achievable, and they directly protect App Store ratings and retention.
73%
of all e-commerce transactions now happen on mobile devices
If your business relies on e-commerce, service bookings, or any kind of transaction, mobile is your primary channel. We build conversion funnels specifically for thumb-reach navigation, fast input, and accelerated checkout, not desktop experiences scaled down to fit a smaller screen.

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