I noticed there was no simple way to achieve this with any note taking app, so I made one.
* every line you write is automatically timestamped.
* minimalist and distraction free - follows the simplicity of the built-in note apps.
* cross platform - it's a webapp so no install required, works great on mobile, web, android, iOS, tablets.
you can use it for free, no email and no signup required.
I made this first version where data is stored locally on your device.
Sharing here in case someone finds it useful, it would be great to know I solved the same problem for anyone else :)
