I have found 0 problems
Awesome , only reason 4 stars is cuz it is slow,But it is probably just my phone
Make a $1.00 version with no ads and I'll buy it. Until then it will remain uninstalled. I would also take out the app icon on the top corner when using the app as it looks badly out of place and clashes with the feel and look of the notes. The letters also need some more work as they look pretty choppy and when clicking a note the keyboard should not appear unless I touch some kind of edit option. With additions and fixes like these you should be able to get away with charging at least a dollar for it.
When you select text that's long enough for the screen to scroll then the copy button isn't available which means you have to type out notes word by word if you want to send them to somebody else or copy them into another app. The delete button is also right next to the save button and there's no screen to confirm that you want to delete a note and this has lead to me deleting some quite long notes because my finger hit a centimetre to the left of where I was aiming. Long notes also cause lag.
I actually love it, and it would be my go to notes app, but the dates don't update; every note shows the same date as when I installed the app. Sadly that makes it useless and drops from 5 stars to 1. Very basic and easily fixable screw up!
You could add color changing
Doesn't write on the lines. Has lines going through the text.
For some reason on the title, I would put three words and it would go over the date. Please fix and I will give it five stars.
Nice and simple.
