Ratings and reviews

Useful but the ads are stupid for a note app and I can't put the pictures with the proper points they need to be under. The pictures just stay at the top. (This is my reply to the owner's reply) Thank you for replying. I didn't mean for my review to sound rude. If it did sound rude, I'm sorry. I understand the ad thing more better since you said you're a solo developer.

I like how handy the app is, but as of late it has duplicated or deleted notes.

... so far everything is fine ... spendid an' simple ... brothers give us more colors in order to label all notes ... worth to be lived & loved ... cheers ...
