General questions

You can download the Android and iOS version in Google Play and Apple App store (soon):


During installation, you must grant full permissions to use the location (always, also in background mode) in order to make the app work properly.

Please note that rooted/jailbroken devices and some special OS versions are not supported.

The app costs about 6€, depending on which country you buy the app from.

From May 2021:

The cost to use Balloon Live for your competition is a one-time fee per event, to be paid by the organiser. Balloon Live team will set up an event for you on watchmefly.net. You will then be given access to the competition center on watchmefly.net to manage the competition, flights and tasks, distribute registration tokens and download the tracks. The fee depends on the number of scheduled flights of your event:

      • 1-3 flights: 50€
      • 4-7 flights: 100€
      • 8+ flights: 200€

This fee will be waived for all events starting before May 1st 2021.

Every pilot needs to buy "competition credits" within the app. For each competition a pilot registers and competes in, he will be charged one credit. Credits are available at around 10€ each, depending on which country you buy the app/credit from. No credits are needed for event starting before May 15th.

Note: These fees are considered a project income and will go directly to the FAI Ballooning commission to develop, run and maintain the app and the backend systems.

To use it in your event/competition, please contact the Balloonlive-team using the event setup request form.

The team will get back to you with the details on how to pay the fee for your event.

Once payment has been received, the team will create an event for you and give your managing access to it on watchmefly.net.

Until March 2021 the app only supported the internal location sensor (GPS) of the phone/tablet used. The accuracy of the position may vary depending on the device model and technology used.

Balloon Live Sensor

For FAI CAT1 events and others, a special external sensor box, the Balloon Live sensor, with standardised sensors will be available as of April 2021. The sensor can be used in national events too.

Using the app

The best way to make sure no problem occurs is to keep the app in the foreground and the screen switched on all the time.

On most phones you may  use a different app or sleep the phone for a few minutes.

As this may differ depending on the phone manufacturer or model, especially for Android, we strongly recommend to test that the app is not put to deep sleep , hibernate mode or completely killed and the track still properly recorded after 5 or 10 minutes of phone sleep or using another app.

On iOS a notification will pop up every few seconds (if notification permissions given). This is used to keep the app alive in the background for a few minutes.

For now you can use multiple phones and register each with the same pilot code to the competition.

To not confuse the scorers and overload the servers, we recommend to use your backup phone(s) in training mode and provide the stored track via email or other transfer method to the scorers.

The tracks will remain on the phone until you delete the app.

You can delete an individual track file on the phone after 5 days. Swipe the file name to the left to show the delete button.


About Balloon Live Sensor

Yes. It has bluetooth connectivity (BLE) to the Balloon Live app (phone or tablet) and a separate bluetooth connectivity (Bluetooth SPP profile with NMEA) to up to 2 devices (laptop) to be used for mapping applications. All these connections can be used at the same time.

No. Unlike with the previous FAI Balloon loggers, FAI Ballooning Commission will not create a pool of devices that can be rented by event organisers. In upcoming events using Balloon Live, the pilot will be required to bring his own Balloon Live Sensor to make sure the quality of the position recorded for scoring is the same for all pilots.

The event organisers usually decide what logger system they want to use. 2020 has shown that many event organisers are interested in using the Balloon Live app with the Balloon Live sensor in the future as this is meant to replace the FAI Logger used so far. Among these are organisers of regional and national championships as well as larger events. There is no decision made on the next Europeans and Worlds yet, but as soon as we know, we will post the information here.

The initial order was made through a special purchase event which was held in November 2020. Over 500 devices were ordered by pilots from around the world. Another sale event will not be schedule before the end of 2021.

If you missed the sale event and I you wish to purchase a device sooner, please contact your Flytec Balloon dealer for an individual purchase.

The recorded track is stored in up to 3 locations:

  • The Balloon Live app stores a recorded track and it can be shared as IGC file through the normal sharing possibilities on the device.
  • The Balloon Live Sensor additionally stores the track in IGC format on its SD card.
  • If you use Watchmefly.net for the competition, the track is also transferred to watchmefly.net once the phone/tablet is online.

The Balloon Live Sensor comes with an SD card (inserted into the slot), a pouch for protection, a lanyard to secure it while using it in a balloon, a velcro strap to attach it to an upright, and a micro USB to USB-C adapter. To keep the cost of the device low, the box does not contain a charger. Instead you can use any charger with a USB socket that you already have.
