Ltt.rs for Android
Proof of concept e-mail (JMAP) client (pronounced "Letters"). Makes heavy use of Android Jetpack to be more maintainable than some of the other Android e-mail clients.
If the above screenshots don’t do enough to convince you, you can watch this short video on YouTube.
Features, and design considerations:
- Heavily cached, but not fully offline capable. Ltt.rs makes use of JMAP’s great caching capabilities. However, marking a thread as read does round-trip to the server to update things such as read count. The action itself won’t get lost even if performed offline.
- Account setup and done. Settings invite feature creep and its friend unmaintainability.
- Minimal dependencies. Third party libraries are often of poor quality, and end up unmaintained. Only widely known, highly tested libraries from reputable vendors.
- Native Autocrypt support.
- Based on jmap-mua, a headless e-mail client, or a library that handles everything an e-mail client would, aside from data storage and UI. There is also lttrs-cli, which uses the same library.
- Looks to Gmail for inspiration in cases of uncertainty.
Attention: You need a JMAP capable mail server to use Ltt.rs
If you want to use F-Droid you can also use our F-Droid repository instead of the official one:
All three versions are signed with the same key, so it is possible to switch between them.
During setup, Ltt.rs will ask you for a connection URL.
