Great app. Easy way to store password information without any extra fuss. The password generator is really handy as well. I'm satisfied with the app as it is, but I do have a suggestion. The icon selection for custom categories could use more color options for people that like to organize things with colors. You could just take the gray icon that's used in the "other" category and make it different colors.

Excellent offline manager. Found A BUG. When you add more than 18 categories it gets buried and you can't click it to add information. It needs the ability to scroll when you're in the "My Passwords" section so you can click them. Other than that, so far an excellent app! Awesome, another thing I noticed is sometimes when you change the category names and hit save they don't change. It would be nice if we could organize below the titles. Once added, only choice is to delete them and start over.

I really enjoy this password 🔑 manager. It's an offline app, which I prefer, with available settings that let you choose the number of characters used in a password. You can customize each entry with some predefined options. I would like to see additional customization options within each individual password entry. I have had some difficulty adding multi-line text but haven't used it since before the most current update. Overall this is a simple, clean failure free app that is easy to use!
