Jmelgar

This is the best app I have ever used to protect my passwords. I recommend using this very highly.

Cat

Love this app. Try it you’ll love it.

Search Function?: NoteLock

Very good App. I use this App a lot
However, there should be a search function in that App. In absence of this, I am wasting my time searching for a particular word which I saved it long time back.

Note Lock Wonder

I love this app! Used this for my passwords notes so I won't forget!

Doesn’t work correctly

I unlocked all the options and they don’t work on my iPad Pro.
I’m waiting for an answer from them now…
