TripN shares your movement via automatic SMS messages.

Whether you need someone to follow you in real-time, for safety purposes or just for fun, then TripN is just the app for you!!



Unlike other apps where one manually still have to press the "Send" button for each individual SMS to be sent, TripN sends each message automatically. Recipients do NOT need a smartphone to receive the SMS. The SMS is delivered to any mobile device that can receive standard text messages.


TripN runs in full background mode, allowing users to multitask. This means that one can dial/receive calls, send/receive emails or use other apps while TripN is sending its automatic location messages in the background. Perfect for when using other navigation-apps on the same device, to track ones progress on a map or maybe using the phone's camera to take photos etc.



TripN accurately calculates, puts into a SMS and automatically sends your:


  • Position on earth [latitude and longitude]
  • Altitude
  • Current speed
  • Your general direction of movement
  • A selectable link that immediately opens a map with your position on the receivers’ device.
  • Any additional info that you want contained in the SMS [your name, destination, ETA etc.]

And when you don’t want to send any info – TripN is great if you simply want readings of your current location, speed, altitude etc. as all the above mentioned data [and more] is displayed on the screen for you to view.



Share your trip’s progress, or be monitored or tracked for safety purposes:


  • Flying your aircraft – have someone flight-follow you.
  • Sailing your boat – have someone track your coordinates.
  • Hiking alone or in a group, cycling in remote areas or driving in high security risk areas - send accurate information regarding your position, just in-case anything happens!
  • The list of activities is endless, horseback riding, dog sledding or hunting excursions!

Just hit the Activate-button and leave it to do the sending for you. No need for any other input from that point onwards until you wish to stop sending updates. Truly set-and-forget – even when the device has Auto-Locked!!!

TripN does not use the users’ mobile text facility but rather a brief data connection. Users register an account with and receive a key and secret code and enter that into the TripN settings once only and you're done! Your device uses minimal data to send the SMS! Some countries like the United States and Canada, requires a Local Long Virtual Number to be added too. Nexmo charges for each SMS sent, but the costs are very low. Please visit find out if you need a Virtual Number and for SMS pricing pertaining to your country.


If you would like to use TripN but without having to sign-up to Nexmo, please download TripN Express.

Things you need to know:


It will only send messages if you have a data connection to your mobile device service provider or a Wi-Fi connection. It should not be your only means of safety when conducting a trip. TripN is not responsible for errors locating your position or failure of message delivery. Using Location Services may decrease battery life. When running in the background, TripN will discontinue sending messages when it has sensed no movement for a while.
