Mobile App Development Agency for iOS and Android
A mobile app is a serious investment. Tkist Digital 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 Challenge
Why 81% of apps don't survive their first three months, and how to be the exception
Most apps die within weeks of launch, not because the idea was bad, but because the experience was built on assumptions instead of real user behaviour. Clunky onboarding, slow load times, and ignoring platform conventions all kill retention fast. Every time we've taken over an app from another studio, we've found the exact same structural mistakes.
Launching an app is the easy part. Getting people to open it every day for a year straight is the real challenge. We build retention into the wireframes from day one, not as a fix bolted on after download numbers stall.

Package Contents
Everything bundled into your mobile app development engagement
View Full ScopeiOS Development
Native Swift development for iPhone and iPad, optimized for latest iOS versions.
Android Development
Native Kotlin apps built to Google Play guidelines and Material Design standards.
React Native
Single codebase for both platforms when commercial speed is the priority.
UX & Prototyping
Full UX design with interactive prototypes reviewed and signed off before development starts.
Backend & APIs
REST and GraphQL API design, Firebase, Supabase, or custom Node.js backends.
App Store Submission
Full submission management including App Store review handling and ASO.
Our Process
From the first conversation to results you can measure
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.
Choosing a Platform
Native or cross-platform: the call our mobile app team walks through with you before any code gets written
We'll walk through this together on the free discovery call, but here's how our mobile team approaches the decision before any code gets written.
Best for: Complex apps, fintech, health, fitness wearables, or anything where UX precision defines the product
- Top-tier performance and frame rates (60fps as standard)
- Complete access to platform APIs, camera, AR, biometrics, background processing
- Matches Apple's Human Interface Guidelines and Material Design exactly
- Lower maintenance burden over time since OS updates are handled natively
- Necessary for apps with complex animation, real-time data, or hardware integration
Best for: B2B tools, internal apps, marketplaces, booking platforms, or anything where shipping on both platforms quickly is the priority
- One codebase covering iOS and Android at once, roughly 30–40% cheaper to build
- Faster time-to-market for MVPs and early validation
- Shared business logic, API calls, and state management across platforms
- Solid performance across most app categories outside high-frame-rate or hardware-heavy use cases
- React Native runs production apps at scale for Meta, Shopify, and Coinbase
By The Numbers
Five reasons apps die in their first 90 days, and how we design around every one
81%
of apps get deleted within 90 days of being downloaded
An app only earns product status once it's opened a second, tenth, and thirtieth time. We start planning for retention at the wireframe stage, not after download numbers disappoint. Onboarding flows, habit loops, and push notification strategy all get mapped before any code exists.
53%
of users uninstall an app because onboarding left them confused
The first three minutes determine whether someone ever comes back. Every project gets a structured onboarding workshop, mapping the fastest route to that first 'aha' moment, when a new user understands why the app is worth keeping.
4.4+
App Store rating needed to keep download momentum; below it, installs drop 70%
The App Store algorithm rewards apps with strong ratings and a steady flow of positive reviews. We build review prompts into every launch, triggered right after a good moment rather than a frustrating one, so almost every app ships with a review strategy already in motion.
60%
fewer crashes when QA covers 50+ real device and OS combinations
There are more than 40,000 active device and OS combinations across the App Store ecosystem. We test on 50+ physical devices before every submission rather than trusting simulators alone. Crash rates under 0.5% from day one are achievable and directly protect ratings and retention.
73%
of e-commerce purchases now happen on mobile
If your revenue comes from products, bookings, or any kind of transaction, mobile is your main channel. We design for thumb-friendly navigation, simplified input, and fast checkout, rather than just shrinking a desktop layout to fit a smaller screen.
A Real Outcome
Health & Fitness, Sydney, Australia
Achieved a 4.8-star App Store rating with 12,400 monthly active users just 6 months after launch.

We'd been through two agencies and two failed builds before finding Tkist Digital. The difference showed immediately, they cared about asking the right questions before writing a single line of code.
