OnMemo - Lock Screen Note

OnMemo is an Android app that keeps the memos you do not want to forget close at hand on your lock screen and over other apps.

Lock screen
Arrange your important notes in the order you prefer and see them when you turn on the screen. The status notification summarizes up to three note titles. Lock-screen visibility depends on your device's notification and permission settings.

Photo notes
Save your parking spot or a scene you want to remember. Add one photo or screenshot and a short caption to a lock-screen note. Tap the photo to view it in full and zoom in or out. Change or remove just the photo while keeping your note text. Saved photos are copied into the app, so deleting the gallery original does not remove them from your notes.

Over other apps
Explicitly select one memo to show over other apps. This feature uses Android's display-over-other-apps permission and includes an ongoing notification so you can stop it at any time.

Settings
Manage notification and overlay permissions, appearance, and app information in one place.

Your memos and settings are stored on your device. OnMemo uses the Google Mobile Ads SDK to serve ads, and the ad service may process device and usage data. The app has no account or memo-sync feature.

Key features
- Write and reorder lock-screen notes
- Show one explicitly selected memo over other apps
- Exclude sensitive memos and memos not suitable for public display
- System, light, and dark theme preferences
- Save a photo or screenshot with a short note and view it in full

Lock-screen notification and overlay behavior can vary by Android version and device maker. OnMemo follows Android permissions and your choices.
