### 4/5 — Good so far

*2021-07-15*

Would be nicer if you could revive the background pattern at the top, also a fake pair that lets you store fake notes. Also, when putting your phone face down, it should switch to your desired app so you doing get caught with your notes, like the “secret photo album - sa” app

**Developer response:** Thank you for using my app!  
I will continue to improve my apps.  Please continue to use my apps!

### 5/5 — Hi

*2019-06-09*

I love this app but I think that you could add word suggestions like autocorrect and I think you should be able to change the color of the text when writing 
Please take note of these things but they are only suggestions to the app otherwise it’s great.

**Developer response:** Thank you for using my app!  
I will continue to improve my apps.  Please continue to use my apps!
