The app functions as a remote keyboard for the Shwa script (www.shwa.org). It needs to put Shwa letters in the keyboard buffer of PCs connected via Bluetooth, and to operate under Android and iOS, and under Windows and MacOS on the desktop side.
The app itself is simple. The hard parts are:
- the Bluetooth connection
- on the mobile, using a Shwa font that isn't installed
- getting it into the app stores
- updating it as needed
