Read full descriptionHide full description
Simple Hidden Note is a lightweight, free and offline note taking app. Simply and only made for Text note taking. By default plain text, with minimal formatting possible if required. The main feature is the hidden part. Notes are hidden by default. Creating a new note works the same as accessing an existing note: you authenticate then enter any pin. The collection of single notes will be available under that pin then. The app automatically exits hidden notes when in the background. Alternatively you can "unlock" any note collection to make it visible and accessible from the app home screen. [Features] ⢠One text note collection per entered pin. Any pin. ⢠Unlocking notes means usability like a simple text note editor. ⢠Biometric authentication before pin entry. ⢠Light and dark modes ⢠Note collection import, export and sharing ⢠No cost, no account, no advertising Be aware that notes are not encrypted by the app though. The app also works together with our Containd app by linking each inventory item to a pin/ note collection in Simple Hidden Note. And that note then links back to Containd App to the respective item. Just in case more text is required.
