Frequently asked questions
Can another developer take over the app later?
Yes. We build with standard, widely used technology, not a system only we can work with. Once the final invoice is paid, the code is yours and the app is published under your own developer accounts. Another developer can simply carry on.
Do you build for both iOS and Android?
Yes. We build from a single codebase, so you get 1 project, 2 platforms, and consistent performance on both.
Do you handle app store submission?
Yes. App Store and Google Play submission is included in the App Starter package. We handle the process so your app goes live on both stores.
What about app updates after launch?
App Starter includes 30 days of post-launch bug fix support. After that, you can pick a Maintenance, support & hosting plan or ask for a custom retainer for ongoing development.
Can you add in-app purchases?
Yes, as an add-on. In-app purchase and subscription setup are added to your project scope via a quote request.
