Top comment

I built Plainsum because I wanted a notepad that could do the work without making me set up a spreadsheet. Just type, get an answer, keep going.

It’s free, works offline, and keeps your notes on your device.

This is my first app, and I care about getting the everyday details right. If you try it, tell me where it gets in your way or doesn’t understand what you typed. That’s what I want to improve.
