I just want a free minimalist app on my phone that lets me enter a date on one column, and a bunch of other values in other columns. I don’t even need it to perform math, but I won’t mind if it does. Bonus points if I can export the data, but not a deal breaker. I don’t need any sync.

I could be using Google Sheets but fuck Google and also I want to keep my data local and private on my phone.

Thanks
