Mobile App Development
We build mobile apps for iOS and Android, from first release through store submission and ongoing maintenance. As a small senior EU-based team working with clients worldwide, we are honest about the trade-offs: most apps are best served by a cross-platform codebase, and we will tell you when yours is not.
What we do
Our default is cross-platform development with React Native or Flutter: one codebase, two platforms, and a shorter path to release. For most business apps — customer apps, field tools, companion apps for a web product — this is the right call, and it keeps long-term maintenance costs sensible.
We recommend native development with Swift (iOS) or Kotlin (Android) when the app depends heavily on platform APIs, demands sustained high performance (intensive graphics, audio/video processing), or needs complex background behaviour. We will make that recommendation during scoping and explain the cost difference, because the decision affects your budget for years, not just this project.
In scope
- Cross-platform apps with React Native or Flutter
- Native iOS (Swift) and Android (Kotlin) where it is genuinely needed
- Backend and API work to support the app, or integration with your existing backend
- App Store and Google Play submission, including review feedback cycles
How we work
Mobile projects have a step web projects do not: the store review process. We plan for it from the start rather than treating it as an afterthought.
1. Scoping & platform decision
We define the feature set, agree on cross-platform versus native with written reasoning, and map any backend work the app needs.
2. Build with test devices
Iterative development with builds distributed to your team via TestFlight and Google Play internal testing, so you use the real app on real devices throughout.
3. Store submission
We prepare store listings, privacy declarations, and review notes, submit to both stores, and handle rejection feedback until the app is live.
4. Post-launch maintenance
OS releases and store policy changes do not wait. We offer ongoing maintenance so the app keeps working as iOS and Android move underneath it.
What you get
Everything is delivered under your accounts and your ownership.
Source code
The full app codebase in your repository, with build configuration for both platforms.
Store presence
Published apps under your own Apple and Google developer accounts — never ours.
Release documentation
Step-by-step release instructions so future versions can be shipped without us if you choose.
CI builds
Automated build and distribution pipelines for test and release versions.
Typical engagements
Typical mobile work falls into a few patterns:
Companion app
A mobile app on top of an existing web product, reusing your current backend and accounts.
Standalone product app
A new app with its own backend, built and submitted to both stores as a complete product.
Rescue and update
An existing app that no longer builds or was rejected by a store, brought back to a releasable state.
Frequently asked questions
Cross-platform or native — how do you decide?
We start from your requirements, not a preferred technology. If the app is mostly screens, forms, and data — as most business apps are — cross-platform wins on cost and maintenance. If it leans hard on platform features or performance, we say so and quote native honestly.
Do you handle App Store and Google Play submission?
Yes, including store listings, privacy labels, and responding to review rejections. Apps are published under your own developer accounts so you keep full control.
What does maintenance look like after launch?
iOS and Android release major updates every year, and dependencies deprecate steadily. A modest maintenance retainer keeps the app building, compliant with store policy, and up to date. Details are on our maintenance and support page.
Can the app use our existing backend?
Usually yes. We review your current API during scoping and flag anything that needs adjusting for mobile use, such as authentication flows or payload sizes.
