Editor's Overview

FMD is a emergency action application developed by F-Droid Open Source, packaged as a single Android APK of version 0.2 weighing in at 6.59 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 6.59 MB, so it installs quickly even on modest connections.
This build is signed by "F-Droid Open Source" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

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 lose 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.

Frequently Asked Questions

Is FMD free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does FMD require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is FMD safe to install?
We link to the exact APK published by F-Droid Open Source. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update FMD?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
