This is what BackChecker looks like: safeguarding and alerting in an emergency

This is how BackChecker works:

3 iPhone 7 Neuer BackCheck Webpagewebpage
  1. Set duration until your return
  2. select up to three emergency contacts from the list
  3. Enter additional information
    e.g. “I am out for a ride” or “Meet me with Max87 from the x-chat”
  4. (Activation of the Password / Safeword function secures against forced BackCheck termination)
  5. Start

The app now transmits the information entered and the ongoing geo positions to BackChecker’s data center for the current BackCheck, ie for the selected time-sensitive security window.

After having returned safely, the completed button ends the entire BackCheck, all data is irretrievably deleted. (! Closing the app – on Android also the back button – does not stop the countdown alarm!)


3 alarm types:

  1. Instant Alert: With a mobile internet connection, you can trigger an instant alert by pressing the Instant Alert button three times while a BackCheck is in progress.
  2. Countdown-Alarm: The alarm is triggered automatically by the backend after the expiration of the set duration and thus works also in areas without a mobile internet connection or if you are unconscious. You will be reminded 3 times beforehand and can still adjust the time while having a connection.
  3. Silent Alert: Will you be forced to quit the BackCheck, enter your safeword instead of a password. The app pretends the normal termination, at the same time your helpers receive an immediate alarm in the background.

If an alarm is triggered, all emergency contacts selected for this BackCheck will be alerted via SMS. Here is a real BackCheck from us as an example (Depending on the connection, loading may take a little longer due to the live position transfer of the map.)

Step-by-step explainer video

For BackChecker to function optimally, the following applies:

  • Allow GPS / location services so your location data can be tracked when in use
  • Allow messages or notification to receive the expiration warning (if you ever forget to stop the BackCheck on arrival)
  • Sound to hear the expiration warning sounds
  • Temporary network connection for start and stop, as well as for extending and for the immediate alarm, so that the App-Server can receive and implement your command.


Why do I need a network connection for some actions, while later on I am also secured independently of the network, no matter what happens?

When you start a BackCheck on the app, all information is transferred to our computer systems, so basically your saveguarding is not running on your phone, but our computer systems. That’s exactly your biggest advantage, no matter what happens to you or your cell phone in the meantime, your trusted people will know something is wrong.

With “Start BackCheck” you give the command: “If I did NOT finish the BackCheck regularly by that time and therefore did NOT confirm that I am safely back, then notify my emergency contacts!” Conversely, this means that ALWAYS trigger the alarm when your BackCheck expires. Closing the app does not stop the current BackCheck, but only the regular shutdown – in the app or, if the phone is broken, via emergency stop on top of our website.
