# Custom Mobile App

Our mobile app Mergin Maps mobile app provides seamless synchronisation of field data between mobile devices and Mergin Maps service. However, we know that sometimes people want a mobile app optimised for a specific use case: maybe you just want to change the branding or disable some functionality - or maybe you want a bigger overhaul of the user interface.

The good news is that Mergin Maps mobile app is licensed as open source software, which means that anything is possible with a bit of development!

If you are interested in building a custom app, you can start by going to MerginMaps/mobile (opens new window) repository on GitHub and building it for your platform.

The mobile app SDK repository (opens new window) provides all the dependencies for various platforms (Android, iOS, macOS, Windows).
