SERVICE AD-02
App Development
We build cross-platform mobile apps for iOS and Android, web applications, progressive web apps, and internal tools that replace spreadsheets and manual processes. That includes the API and backend work underneath them, and support through App Store and Google Play submission.

HOW IT RUNS
How the work runs
Durations are typical ranges. Your written schedule replaces them with dates once scope is signed.
- 01
Requirements and scope
1–2 weeks
Users, flows, data model and integrations written down and signed off.
- 02
Prototype
1–2 weeks
Clickable screens for the core flows, so decisions are made before code is written.
- 03
Build
4–10 weeks
Iterative builds you can install and use, with backend and app developed together.
- 04
QA and hardening
1–2 weeks
Device testing, edge cases, error handling, performance and security review.
- 05
Release and support
1–2 weeks
Store submission, review responses, production release and monitoring.

QUESTIONS
Frequently asked
- Do you build separate iOS and Android apps?
- Usually not. We build one cross-platform codebase in React Native or Flutter that produces both builds, which keeps cost and future maintenance lower. Where a feature genuinely needs native work, we write that piece natively and bridge it.
- Who owns the App Store and Google Play accounts?
- You do. We ask clients to hold their own Apple Developer and Google Play accounts and add us as a delegate. If you prefer, we can submit from our accounts during the build and transfer the app afterwards, which is set out in the service agreement.
- What happens if a store rejects the build?
- Rejections are a normal part of release. We respond to the reviewer, make the changes the guidelines require, and resubmit. Rejections caused by our build are fixed at no extra cost; rejections caused by your business model, content or account status are addressed together.
- Can you work with our existing backend?
- Yes. We can build the app against an API you already run, extend that API, or build a new backend. We start by reviewing what exists and telling you plainly whether it will support the app you want.
- What does maintenance look like after launch?
- Mobile platforms change every year, so apps need periodic updates for new OS versions and store requirements. We offer a monthly retainer covering updates, dependency upgrades, monitoring and small feature work.
