Memolio is an Android app that turns a spare tablet into a local digital photo frame. Photos are added from a phone or computer on the same Wi-Fi network by scanning a QR code shown on the frame.
The app is pre-release. The current Android package is com.baer.memolio, with version name 0.1.0 and version code 1.
The Google Play listing goes live at release. The closed test is open now — join the group to opt in.
- Fullscreen photo frame with an analog or digital clock, date, optional captions, shuffle, slideshow intervals, fit modes, and crossfade with Ken Burns motion.
- Face-aware smart crop: in fill & crop mode the crop biases toward a detected face, using an on-device (bundled, no network) face detector, with a center fallback when no face is found.
- Local browser upload page served from the tablet over Wi-Fi.
- QR upload links protected by a generated token that can be rotated in the app.
- JPEG, PNG, HEIC, HEIF, and WebP upload support.
- Private on-device photo storage with display caches and thumbnails.
- SHA-256 photo deduplication.
- Room database for photo and album metadata.
- AndroidX DataStore for app settings.
- Recently Deleted storage area with optional 30-day cleanup.
- Localized app text and upload-page text for English, German, French, Italian, Dutch, Polish, Portuguese, Spanish, Russian, and Simplified Chinese.
Free includes the frame, Wi-Fi upload, one photo pool, slideshow settings, storage management, language selection, and built-in wallpapers.
Pro-gated features in the current tree:
- Albums and album-based playlists.
- Appliance features: auto-start on boot, kiosk lock, Home-app mode, scheduled sleep, and ambient dimming.
- Custom wallpaper: import your own image as the frame background.
The built-in wallpapers are default (a live vector background), ember, and slate, and are free. Importing a custom wallpaper is Pro.
Pro purchase and restore use RevenueCat over Google Play Billing. After a successful purchase or restore, the entitlement is stored locally so the frame can keep running offline.
Memolio has no accounts, analytics, ads, crash-reporting SDKs, or cloud photo storage.
Photos uploaded through the QR page go directly from the uploader's browser to the tablet over the local network. They are not sent to a Memolio backend. The app only makes outbound purchase-related calls when the user buys or restores Pro.
The app does not request broad photo or media-library permissions. It manages files inside its own private app storage.
