Hi folks,
So, following the FastContact announcement, I decided to continue the development basic app suite for the future GerdaOS versions, but these apps can also be used fully stand-alone on non-rooted devices. And this one is FastLog:
https://gitlab.com/suborg/fastlog/
Please carefully read the README file. It follows the same UI principle as FastContact, featuring T9-like search and call blocking list management. You can also perform a one-time import of existing stock call log records upon the first installation (and phone reboot, due to a bug in KaiOS preventing other apps from seeing an already open DataStore). Afterwards, the two call logs work in parallel and don't intervene with each other.
Please note that this is still in the early development. If you have any questions regarding the app, feel free to ask them here.
Stay tuned!
