WolLight

Wake-on-LAN app with device list, LAN scan and stale-IP recovery. LAN-only.
New in version 1.0.8
- Fixed the boot monitor legend so its markers match the ping cells (check, cross, empty frame).
- Removed a stray dot at the right end of the progress bar.
WolLight sends Wake-on-LAN magic packets to PCs on the same local network and
keeps a small list of the devices you wake regularly.

Features:

* Wake-on-LAN: sends a standard magic packet as a UDP broadcast on the local
network, with a configurable port.
* Registered devices: save the devices you wake often with a name, MAC address,
broadcast address and port. The list is kept on the device.
* LAN scan: detects the current Wi-Fi subnet and probes addresses in parallel to
list reachable hosts, attempting host-name resolution over NetBIOS and mDNS.
* Online / offline indication: a per-device indicator based on ping results,
refreshed on app start, on return to the foreground and on manual ping. The
state only changes after two consecutive matching results, to reduce false
readings from transient packet loss.
* Ping: sends ten pings at one-second intervals and shows each result plus a
summary.
* Stale-IP recovery: if a Wake-on-LAN or manual ping fails to reach a registered
device's saved IP address, WolLight runs one LAN scan and looks for the same
device by its registered MAC address. If it is found at a different address,
the saved IP address is updated only after you confirm.

Privacy and network behaviour:

* All traffic stays on the local network. Magic packets, pings and host-name
resolution (NetBIOS, mDNS, ARP) are local-network only.
* No account, no cloud sync, no external HTTP services.
* No analytics, telemetry or crash reporting.
* Registered device details are stored only in a local database on the device.

Limitations:

* Local network only. Wake-on-LAN uses broadcast packets, so only devices on the
same LAN can be woken. Waking a PC across the internet needs a separate VPN or
port-forwarding setup that WolLight does not provide.
* The target PC must already support and be configured for Wake-on-LAN in its
BIOS/UEFI, network adapter driver and (on Windows) power settings.
* Whether the PC actually wakes depends on that PC's hardware and settings, not
on WolLight. Waking from full shutdown (S5) in particular depends on the PC,
its NIC and the OS power configuration.
* UDP is connectionless, so delivery of a magic packet cannot be confirmed. Use
ping to check whether the PC has come up.

Requires Android 8.0 (API 26) or later and a Wi-Fi connection.

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.

  • Version 1.0.8 (9) suggested Added on Oct 16, 2026

    arm64-v8a armeabi-v7a x86 x86_64

    This version requires Android 8.0 or newer.

    It is built and signed by the original developer, and guaranteed to correspond to this source tarball.

    Permissions
    • view network connections
      Allows the app to view information about network connections such as which networks exist and are connected.
    • view Wi-Fi connections
      Allows the app to view information about Wi-Fi networking, such as whether Wi-Fi is enabled and name of connected Wi-Fi devices.
    • allow Wi-Fi Multicast reception
      Allows the app to receive packets sent to all devices on a Wi-Fi network using multicast addresses, not just your phone. It uses more power than the non-multicast mode.
    • have full network access
      Allows the app to create network sockets and use custom network protocols. The browser and other applications provide means to send data to the internet, so this permission is not required to send data to the internet.

    • New in version 1.0.6
    - Fixed LAN scan subnet selection when a VPN is active.
    - Scan uses the actual Wi-Fi or Ethernet IPv4 subnet and excludes the device itself.
    - Progress reflects the actual target count. Scans stop safely on network changes,
    ambiguous networks or subnets exceeding 1,024 targets.
