App Maintenance and Support for iPhone and Android Apps
Apps do not keep working on their own. Apple and Google release new versions every year, store rules change, libraries get security fixes, and the services an app depends on change how they work. We look after your live app every month, so it keeps working and someone answers when it breaks.
Has the developer gone, or is the app already broken for customers? Start with the take-over page: it covers the health check and getting your accounts back. Fix or take over an existing app →

LaunchFrom a checklist
A calm launch, from a checklist
We handle the rollout: hosting, signing keys, store submissions and the checks before go-live. If a store rejects a build, we read the reviewer notes, fix what they point at and resubmit. That is part of the job, not an extra.

CLEAR & TRANSPARENT
From Idea to Launch in 4 Simple Steps
Here is what working together looks like. A short written update every week, and every two weeks a version you can try yourself.
01Step 1
Discover & Design
We find out who will use the app and what it must do for your business. Then we agree what is included, the design direction and the price.
What you get:Clear roadmap & visual prototype
02Step 2
Build, with previews
The engineers turn the plan into a working app. You get a written update every week, and every two weeks a version to try on your own phone.
What you get:A version to try every two weeks
03Step 3
Polish & Quality Check
We test the app against the cases that break apps in real use: bad signal, older phones, wrong input, many users at once. Problems found here are fixed before launch.
What you get:Tested before anyone else sees it
04Step 4
Launch
We set up hosting and store accounts in your name, run the go-live checklist, and release to the App Store and Google Play. Then the maintenance package, if you want it, takes over.
What you get:Your app live in the stores

COMMON QUESTIONS
Questions people ask, answered in plain English
What to know before you start your app.
Can you maintain an app built by another team?
Yes. We start with a health check of the code, the libraries and the accounts, fix anything critical, and then take over the monthly care.
How do you handle urgent problems?
The maintenance agreement sets a response time for urgent problems. We find the cause, fix it, and release the fix from a checklist, telling you before and after.
What does a maintenance agreement include?
Updates for new phone and store requirements, security fixes, library updates, monitoring, a promised response time when something breaks, and a short monthly report of what was done.
Do we have to move hosting or accounts to you?
No. Everything stays in your company's name. We work inside your accounts with the access you grant us.
Can you maintain only the app, or only the backend?
Yes. The agreement covers whatever you need looked after, and the price follows that scope.
