Great app but how do you change the password
★★★★★Dave Tyler· Feb 24, 2023
To be able to have a secure app on my phone that requires a password to open it, is perfect. I keep info on it like my banking details and know only l can access them. 5 stars.
★★★★☆Prakash K K· Jul 17, 2019
This App seems a good one. But a major issue I found is the size of the editing window. It is very difficult to make a comfortable editing where I can see only a very few lines of a big note. Scrolling is extremely difficult.

NOT encrypted (updated) Was able to open backup file on other device with no password and data was unencrypted. Can also open file on any computer and read clearly. Doubt there is any encryption on this app. (To respond to your reply... I opened it with a TEXT viewer NOT the app. My tablet did NOT have this app on it. I opened it out of curiosity after seeing other posts and my info was clearly visible to read in text form. Before you blame the other app, it was this app. Opened the .txt file and was readable)

Randomly open without password Multiple time I opened my tablet to see secure memo open. After a few mins of non use it automatically closes session, and u have to reenter password. So why is my secure memo open? I know it wasn't open, I restarted it before bed. You have been warned. Pass on this and go to something else. People use a secure app for securing important info, and it appears to me someone can remotely access it and because it's password protected I'm guessing it's the developer. Skip it and move on.
