Got notes you'd rather keep to yourself? This app is a private notes app that keeps your secrets safe with a password and biometric authentication. While you're writing, the screen is blurred so no one nearby can read what you're typing. Set a simple numeric PIN or a complex alphanumeric password — whichever you prefer — and unlock it in an instant with Face ID or Touch ID. You can also attach photos directly to your notes.
