Comments on Note Locker - Protect notes for Android

★★★★★ Kai Yang Tan · Nov 12, 2021

Simple, easy, clean, works fine. Some suggestions: 1. Allow adding groups/categories/folders. 2. Flagging/tagging notes.

Scared me like crazy, decided to trust them and save my passwords in here. But just a few days later I had someone playing around in my Spotify account. I have no proof that it was because of this app, but I ain't trusting them anymore.

★☆☆☆☆ Bailey Chamblee · May 9, 2023

Not a safe app. Used it to store passwords, and like another user here in the reviews, found my account compromised. Do not use, do not donate to developer, STAY AWAY. THEY WILL STEAL YOUR INFO.

★☆☆☆☆ M K · Oct 30, 2021

In order to save the note, I need to press the "save" button??? What the hell, are you kidding me? The note I wrote is lost. Every other app saves the note automatically
