Free Digital Signage for Android TV and Fire TV (2026)

Turn any Android TV box, Apolosign player, or Amazon Fire Stick into a fully managed digital signage display using the free ScreenTinker APK.

What works

• Android TV (Sony, Hisense, Philips, Onn, NVIDIA Shield, generic Android TV boxes)
• Amazon Fire TV / Fire Stick (4K, 4K Max, Cube)
• Apolosign signage players (Android-based commercial signage hardware)
• Tablets running Android 8+ mounted as in-store displays

Step 1: Get the APK

Download the ScreenTinker APK from screentinker.com/download/apk. The latest signed release is hosted directly so you do not need a Play Store or App Store account.

Step 2: Sideload onto the device

On Android TV

The easiest path is to install the Downloader app from the Google Play Store on the TV, then enter the URL https://screentinker.com/download/apk. Downloader fetches the APK and walks you through installing it. You will be prompted once to "allow installs from this source" - say yes.

On Fire TV / Fire Stick

Install Downloader from the Amazon App Store. In Settings > My Fire TV > Developer Options, enable Apps from Unknown Sources. Open Downloader, enter https://screentinker.com/download/apk, and install.

On Apolosign / commercial Android signage hardware

These devices typically expose a system file manager. Plug in a USB drive containing the APK, open the file manager, and tap the APK to install. Some Apolosign units allow direct URL install via the built-in browser.

Step 3: Pair the device

Launch the ScreenTinker app. The first time it runs, you will be asked to grant a few permissions:

• Display over other apps - so the player can stay fullscreen
• Storage - for the local content cache
• Accessibility service (optional) - enables remote touch and key injection from the dashboard

The app will then show a 6-digit pairing code. Sign in to your ScreenTinker dashboard, click + Add Display, and enter the code.

Step 4: Push content

Same as any other ScreenTinker display:

1. Upload media in the Content Library
2. Build a Playlist
3. Publish the playlist and assign it to your device

Kiosk mode tips

For unattended displays you generally want the device to boot straight into the player with no way for someone to back out:

• Set ScreenTinker as the launcher. The APK declares HOME intent support, so on most Android TVs you can pick it as the default launcher in Settings > Apps.
• Disable updates and notifications on the device to prevent unwanted popups.
• Enable auto-power-on in TV settings if you want the display to come back after a power blip without manual intervention.
• For Fire Stick, use the Wolf Launcher or similar to replace the Amazon home screen.

Hardware recommendations

• Lowest cost: Amazon Fire TV Stick 4K. ~$50 and works fine for image and 1080p video playlists.
• Best value: Onn 4K Streaming Box. ~$30 at Walmart and runs Android TV stock.
• Commercial: Apolosign players. Ship with built-in mount, real-time clock, and HDMI-CEC for power management. Recommended for production deployments.
• Highest performance: NVIDIA Shield TV. Overkill for signage but bulletproof.
