Make your AYN device's lighting your own.
DuoFrost brings screen-matching colours, audio-reactive lighting and custom LED effects to AYN devices. Choose a look, organise your presets or let Smart Scenes adapt your lighting to your apps, games, time and battery.
An independent, open-source continuation of BiFrost, maintained by Stefan van Den Broek (Tufein). The maintainer's device is AYN Thor.

App interface captured in an Android emulator; sample presets shown.
The welcome message now closes cleanly when Android recreates the app screen, including during AYN Thor display changes. An interrupted message is shown again until you confirm it. Patch details.
- A cleaner interface: a clear lighting dashboard, readable preset cards and direct output, mute and timer controls. Layouts adapt to narrow and wide windows, including short landscape screens.
- Smart Scenes: combine apps or game groups, hours, weekdays, battery and charging conditions. Choose a preset or dim the current look, see why a rule applies, and hold a temporary choice for 15–120 minutes.
- A better preset library: favourites, named collections and search work together. Preview saved colours and supported animations before applying them.
- Safer sharing: review imported presets, choose how matching names are handled and opt into app assignments. Undo one eligible import or deletion for ten minutes while no later relevant changes have been made.
- Stability improvements: calmer app/game switching, safer preset handling and backups that include scenes, favourites and collections.
BiFrost's ambient colours, audio effects, Ambi Aurora, separate left/right controls, presets, app profiles, themes and integrations remain the foundation. DuoFrost also adds background controls, brightness limits, sleep timers, temporary mute, widgets and more flexible schedules. See the changelog for the changes from BiFrost and earlier DuoFrost versions.
- Export a full backup and keep it outside the app.
- Download the APK above and open it on your AYN device.
- Follow the first-run guide, choose a preset and grant only the permissions you need.
DuoFrost 2.1.0, 2.3.0, the 2.5.0 alphas and 2.5.0 update in place. Your presets and settings are retained. Keep the backup until you have checked the update.
Original Version 1 or Version 2 needs a one-time reinstall. Export a full backup outside the app before uninstalling. Uninstall the old DuoFrost, install 2.5.1, import your backup and grant the needed permissions again. The original Version 2 APK retains Android version 1.5.1.
Coming from BiFrost? DuoFrost installs alongside it. Export your presets, themes or backup from BiFrost, then import them into DuoFrost. Run one LED controller at a time. For Obtainium, add this repository.
Ambient and audio effects need capture permission. Samples are processed locally; captured content is not recorded or uploaded. For background lighting, allow DuoFrost to run in the background in Android's battery settings. After an Android Force stop, open the app again.
Hidden feature — tidy Recent apps: DuoFrost's window stays out of Android's Recent apps list. Reopen it from its app icon; use Start/Stop to control lighting.
