+# Chrono Logger
+
+Record times active on a task, course, work or anything really.
+
+**Disclaimer:** No one is responsible for any loss of data you recorded with this app. If you run into problems please report as advised under **Requests** below.
+
+With time on your side and a little help from your friends - you'll surely triumph over Lavos in the end!
+
+![dump](dump.png) ![dump1](dump1.png) ![dump2](dump2.png) ![dump3](dump3.png) ![dump4](dump4.png) ![dump5](dump5.png) ![dump6](dump6.png)
+
+
+## Usage
+
+Click the large green button to log the start of your activity. Click the now red button again to log that you stopped.
+
+## Features
+
+- Saves to file on every toggling of the active state.
+  - csv file contents looks like:
+    ```
+    1,Start,2024-03-02T15:18:09 GMT+0200
+    2,Note,Critical hit!
+    3,Stop,2024-03-02T15:19:17 GMT+0200
+    ```
+- Add annotations to the log.
+- Create and switch between multiple logs.
+- Sync log files to an Android device through Gadgetbridge (Needs pending code changes to Gadgetbridge).
+- App state is restored when you start the app again.
+
+## Controls
+
+- Large button to toggle active state.
+- Menu icon to access additional functionality.
+- Hardware button exits menus, closes the app on the main screen.
+
+## TODO and notes
+
+- Delete individual tasks/logs through the app?
+- Reset everything through the app?
+- Scan for chronlog storage files that somehow no longer have tasks associated with it?
+- Complete the Gadgetbridge side of things for sync.
+- Sync to iOS?
+- Inspect log files through the app, similarly to Recorder app?
+- Changes to Android file system permissions makes it not always trivial to access the synced files.
