Mobile app developers
Hire mobile app developers who plan past launch day
Most app projects fail after they ship: rejected in review, broken by an OS update, or abandoned once the freelancer moves on. Our engineers have three apps in production and know what a store update looks like a year in.
What you are getting
4 things that decide this
- 01Senior engineers with apps live in the App Store and Google Play right now, not portfolio screenshots from a demo build.
- 02They plan for store review, OS updates and poor network conditions before the first screen gets designed.
- 03You interview every engineer yourself and can turn down anyone you are not sure about.
- 04The code, the app store accounts and the release process are yours, not held by us.
The two ways this usually goes wrong first
A no-code tool gets an app to a demo fast, then hits a wall. No offline support, no background location, no way past an App Store rejection. A freelancer builds something that works on their phone and stalls in review, or disappears once the invoice is paid.
By the time an operator is searching for an app developer instead of a React Native developer, one of those has usually already happened. The fix is not a better coder. It is someone who has taken an app through review and watched an update break a live feature. That is what builds a real release process.
ExtraaJe, Shift Link and TankAware are three apps our engineers built and still support. Each pairs a mobile app for the people in the field with a web dashboard for the people managing them, on one backend.
What we check before writing a line of code
Store review, planned not survived
Apple and Google reject apps for reasons that have nothing to do with bugs: missing privacy disclosures, unclear account deletion, a login screen with no demo access. We build to their guidelines from the start, so review is a formality, not a gamble.
The OS update after this one
iOS and Android ship major updates every year that can break permissions, background tasks or push notifications overnight. We track beta releases for apps we maintain, so an update is a scheduled check, not a surprise support ticket.
Offline as the normal case
A warehouse, a job site or a moving vehicle rarely has full signal. Actions get saved on the device and sent when the connection returns, with a rule for what happens if two people changed the same record.
Native code only where it earns its cost
Camera, location and background tasks usually work fine in a shared codebase. Heavy graphics or deep hardware access do not, and knowing the difference before you build keeps the budget honest.
- BuildAgainst store guidelines from day one
- SubmitPrivacy disclosures and account deletion in place
- ReviewApple and Google check the whole app, not the code
- LiveStaged rollout, not a single release to everyone
- OS updateChecked against the beta before it ships to your users
Most vendors stop at 'Live'. The last box is where a two-person team with no maintenance plan runs out of road.

How hiring works
- 01
Tell us what the app needs to do
A free call about who uses it, where, and what it replaces. If a simpler tool would genuinely serve you better, we say so before you commit to a build.
- 02
Meet the engineer
We put forward people who have carried an app through review and past an OS update. You interview them directly, not us on their behalf.
- 03
They build in your accounts
Your App Store Connect and Google Play accounts, your repository. Nothing about your app depends on access we control.
- 04
They stay on after launch
Store updates, OS changes and bug fixes under an agreed service level, or a documented handover if you would rather run it yourself. The first 2 months of support and maintenance are free, with every build.

Behind it
Process
Tell us what the app has to survive
Store review, an OS update, a warehouse with no signal, or all three. The scoping call is free, and you leave knowing what the build actually needs.
01Do I need a React Native developer or just a mobile app developer?
You need someone who has shipped an app to both stores and kept it running afterward. Most business apps do not need a specific framework named in the brief. They need a working iOS and Android app, and React Native is usually how we deliver both from one codebase.
02Why did our app get rejected by the App Store?
Rejections cluster around a small set of causes. Missing privacy disclosures, no way to delete an account in the app itself, or a login screen reviewers cannot get past without test credentials. We build to Apple's guidelines from the start, so review is not where a project stalls.
03Our last developer disappeared. Can someone take over the app?
Yes. The first step is getting a build running from what exists and pushing a small update through your own store accounts. That tells us the real state of the code faster than reading it does.
04What happens when Apple or Google release a new OS version?
For apps we maintain, we test against the beta before the public release and fix what it breaks ahead of your users hitting it. An update that quietly stops push notifications or background location working is the most common reason an app stops feeling maintained.
05Do you build the app, or the app and a dashboard to manage it?
Usually both. ExtraaJe, Shift Link and TankAware each pair a mobile app for the field with a web dashboard for the office, sharing one backend. Some projects only need the mobile half, and that works too.
06How much does it cost to build a mobile app?
The number of audiences and how much offline behaviour it needs decide most of the cost. A single-user connected app is a smaller build than a field app with an office dashboard and an admin view behind it. Scoping calls are free. Where we need to assess an existing app first, a paid two-week diagnostic gives you a fixed price before work starts.
