Works with each Android version from 2.0 (API 5)
One of the goals of the app is to provide smooth experience for older e-paper devices like Nook Simple Touch (NST). There is a separate development branch "epaper-ready" for this kind of devices. The latest apk will always be under this url.
No trackers, no ads, and no device permissions. Open Source Code, available under GPLv2 license.
Project was done for my personal usage, but I am aware that some people prefer simplicity and some need low battery drain and processor usage - thats why I decided to share the project. Feel free to contribute.
