Ratings and reviews

I don't like the new setup, I liked the color coded saved notes. Each month was a different color, easy to categorize by changing the date a note was written, thus changing the months color or year saved. Instead of updating from people's listed issues, just increase the number of setting options so each person can customize their own. Instead of only being able to change the actual notepad they write on. That way they can decide how much they see, what color saved notes are, what font, etc.

Reliable, Secure, and Incredible Support! ​I have trusted this app for over 3 years to manage a massive library of more than 1,700 notes. It handles large amounts of data perfectly without ever slowing down. ​What truly sets this app apart is the developer. I reached out with a specific suggestion for the reading mode, and they implemented a custom update in less 3 days! It is rare to find a team that listens to its users with this much care and speed.

I use this app all the time and am very happy with it. That is until I lost my phone, thankfully temporarily. A fantastic addition would be the capacity to download my notes to my computer through a usb cable so I had a backup not on the phone if it is lost or destroyed. I use the notes for many things I can't afford to forget but do not want available to others. Great if I have my phone but disastrous is my phone is lost or destoyed. 5 stars if this is added.
