TileTalk

This project implements a tile-based messenger. The Android app shows two grids on the main screen.

The top grid belongs to the user, the bottom part can be switched to show the grid of a selected contact.

Users can place icon symbols and messages into their grids, and share their grids with others, who in turn can respond with symbols and comments that they place on the user’s grid. Press the palette symbol, choose a Unicode or emoji from the picker grid by double-tapping, and then tap on any green grid cell to insert and type a message into it.

Tiles can be set to “emote” stored messages and do simple animations.

Long-press a tile to edit it.

Tap to see the stored message and comments – one comment per contact.

There is also a “Thread View” which shows the messages more like a convential “chat” based app.

All messages are end-to-end encrypted and you can import/export your keypair to migrate to a different device.

Downloads

The archive contains source-code for a Jetpack/Android client app, and the corresponding server. The server is set up for a Postgres database, and includes the required migration files.

Supporting my website

You may have noticed that this site does not display ads of any kind. I can't imagine it otherwise – it affords us some serenity. I happily renounce ad revenue, and since maintaining and adding to this website comes naturally to me, it mostly just "factors in" somehow into my freelance work. Just like it does for so many of you. But it does take time and thought and expenses.

So if you happen to be in a position where you can help my work financially ("Buy me a coffee"), then this would show solid appreciation and find my lasting gratitude!

Cómo apoyar este sitio

Quizás hayan notado que este sitio no tiene publicidad. Para mi es una decision muy clara de hacer sin anuncios, aunque eso signifique renunciar a algo de dinero. Ampliar este sitio es una actividad que disfruto, entonces se confunde con mi trabajo freelance, por bien o por mal.

Seguiría haciéndolo, por supuesto, sin contribuciones. Pero si quieren – y si les es posible – apoyar mi trabajo aquí económicamente (“Buy me a coffee”), se los agradeceré de corazón.
