icon I lost my new phone.
And because I don't use Google Services I couldn't locate it and my phone was gone for good.
In the hope that this doesn't happen again, I developed this application, so that I can locate the phone via SMS.

Features:

- Locate the device (using GPS or cellular location)
- Lock the device
- Let the device ring
- Take pictures with the device's camera to see its surroundings
- Factory-reset the device

Usage:

You can control FMD (and thus your phone) either via SMS or via FMD Server.
You send a command to the phone (e.g. "fmd ring") and the phone executes it.

For SMS you can either define a list of trusted contacts (phone numbers) that are allowed to send commands.
Or you can set a PIN to allow anonymous usage.
Then non-trusted phone numbers can also send commands by including the PIN in the message.
This is useful because now if you loose your phone, you can ask a random person for help to wipe your phone remotely.
If you simply text "fmd" to your phone FMD will reply with a text listing the available commands.

With FMD Server you get a web interface to send commands, to view the location of your device on a map,
and to view pictures taken by the device.
You can self-host FMD Server.

Disclaimer:

This app is provided on a best effort basis.
We hope it is useful, we use it ourselves, but this is a hobby project
and we can't guarantee that it will work when you need it the most.

WhatsNew:

0.11.0:
- BREAKING: Improved FMD Server protocol. FMD Server 0.9.0 or later is required!
- BREAKING: Change the way on-device PIN verification is done (for SMS and Notification Reply) (!287)
This improves performance. However, during the app upgrade the PIN is reset and you need to configure it again!
- Predictive back gestures on Android 15 (!306, by @GitGitro)
- Bug fixes and tweaks around background jobs and location auto-on/off (!288)

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device.
