Terrible App

These guys are on another planet, when you open the app they don’t let you see whatever you saved until their ad has been on your screen a set amount of time, then they think you’re gonna pay $60 for their app a year just to keep your notes safe. What a rip off

Response from developer

Thanks for the honest feedback, and sorry the upgrade screen got in your way. We hear you. In our next update, out shortly, that screen closes right away, it no longer shows up every time you open the app, and there is a clear Continue with Free option so your notes are always one tap away. Please give the update a try, and if it still does not feel right, let us know. Thank you for taking the time to write.

Most secure

This is the most secure application I have ever came across!

Note edit doesn’t update while in search mode

I write here because I didn’t have an answer from support email. I am a Pro member. I can edit notes correctly from the listing mode, however, when I search a note from search mode and edit it, the note doesn’t appear modified when I go back to the search list. However, if I exit search mode, I can see that the note was actually modified. I was going around this process for half an hour until I realized that, to see the changes I needed to exit search mode. I think that it’s wrong. There should be a way to see the changes stiil in search mode. Otherwise you enter a loop, searching for a note, edit it, back to the results list, edit again, etc. And you never see the changes unless you exit search mode! Could you make this more intuitive please? It’s a great program, however I got stuck in this part until I tried exit search list. Maybe there should be a save button? Or some refresh of the results list . Thanks

Response from developer

Thank you for the detailed report, and sorry the support email did not get a reply. You were right: edits made from search results did not refresh the list until you left search. This is fixed in version 3.6.0, which is available now. Please update and give it another try. If anything still looks off, write to us again and we will answer. Thanks for helping make Secure Notes better!

Great changes

I‘m the one that left the 1-star review a while ago and I’m now bringing back the 5 stars because I’m no longer being punished for not hitting my letters correctly (aka typos) or being bombarded with pop ups :) I got back the app I once loved and appreciated so much.

I‘m happy I was able to give helpful input on how to make users lives easier. The implemented changes improve usability by a lot in my opinion. Thank you for taking my opinion in consideration in the first place. I genuinely wanted to help the Dev(s) because I know the pain on that side of the software too.

Have a good one!

Response from developer

Fair criticism, and thank you for writing it up so clearly — it directly shaped our fixes. Since 3.3 the upgrade popup appears at most once per day. The search bar no longer closes the keyboard on empty results, and autocorrect now works normally — it is only disabled if you explicitly turn on the Secure Keyboard privacy feature. Version 3.4 also brings back the option of a simple 4-digit PIN. We would love to earn back the app you loved before the redesign.

doesn’t let me in

i haven’t used the app since before the new update and it won’t let me in. i typed in my 4 digit pin and it says my password is wrong. i can’t use face ID because i set that up. again, that face ID and password thing is new. the old version just had a 4 digit pin. i have no way to get into my notes. but before the update, it was a good app
