# 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.
