Support

AirTok discovers devices over the local network. Please verify:

• Both devices are on the same Wi-Fi network (not just the same provider)
• The router does not have AP isolation / client isolation enabled (common on hotel / corporate Wi-Fi; blocks device-to-device visibility)
• On iOS, you allowed the "Local Network" permission prompt at first launch — iOS silently drops discovery packets otherwise
• Your firewall is not blocking ports 53317 (TCP) and 53318 (UDP)

If nothing works, use the QR-code connect option to pair manually.

Since iOS 14, multicast access requires a special Apple-granted entitlement. AirTok's multicast entitlement request is pending review. In the meantime:

• Grant the "Local Network" permission on first launch
• Your Mac / Windows can still see the iOS device (one-way visibility)
• Start the transfer from Mac / Windows; iOS will receive a prompt
• Or use QR code pairing

AirTok supports resumable transfers — you won't lose the file:

• Partially received files are stored with a .part suffix
• Unfinished tasks appear in the "Unfinished" section on the Devices page
• Tap "Continue" to resume from where it stopped
• Tap "Cancel" to drop the task — AirTok cleans up .part remnants on both sides

• Confirm the QR code was generated from another AirTok device on the same local network
• QR codes expire after 10 minutes — regenerate if needed
• If the two devices were previously trusted but one of them has been reinstalled, the cert fingerprint has changed. Remove the old trusted-device entry in Settings and pair again

• Weak / congested Wi-Fi is the most common cause; move both devices closer to the router
• Some 5 GHz routers rate-limit UDP multicast — wired or near-AP gives best speed
• SHA-256 integrity check adds ~5–10% overhead; you can disable it in Settings for pure speed
• Many small files are inherently slower than one large file due to per-file handshake overhead

AirTok auto-detects and preserves motion, nothing manual needed:

• iOS → Android: auto-converts to the target phone's native format (Huawei / Samsung / Google / Xiaomi / OPPO / vivo, etc.)
• Android → iOS: reconstructs a proper Apple Live Photo pair
• Playable with long-press after saving to the camera roll

Go to Settings → Trusted Devices and tap the entry. Next send from that device will require re-confirmation.

Useful when:

• The device changes hands (cleaning before selling)
• The other side reinstalled AirTok and the cert fingerprint changed
• You temporarily trusted a shared computer and want to revoke access

Open the app and tap the About tab (bottom right). Version number is at the top. Please include it in any bug report.

• macOS: Drag from Applications to the Trash. App data lives at ~/Library/Application Support/AirTok/ (kept by default); received files are in Downloads.
• Windows: Settings → Apps → Installed apps → AirTok → Uninstall. App data lives at %APPDATA%\AirTok\.
• Linux: apt remove airtok for the .deb, or just delete the AppImage file. Data lives at ~/.local/share/AirTok/.
• iOS: Long-press the icon → Delete App. iOS removes all app data at the same time.
• Android: Long-press the icon → Uninstall. Some OEMs ask whether to clear app data too.

No. AirTok bundles everything it needs:

• Windows: unzip and run, or install via the .exe
• Linux: .deb or AppImage, ready out of the box; needs GTK 3 (shipped with most distros)
