WIf he regularly records one workout after the other with his sports watch, he will quickly learn to appreciate the analytics of the major providers. In the app or in the web browser you can see your best times, come across long-term developments or be amazed at the performance of friends with whom you have connected virtually. In this way, you are tied to the ecosystem of the respective provider, and that is what you want. If all fitness data is stored in the cloud of the respective manufacturer, the change is difficult.
If you still want one, for example from Garmin to Polar or from Fitbit to Strava, you do not lose your own data. Because thanks to Article 20 of the European General Data Protection Regulation there is “data portability” with the right to receive one’s own data in a “structured, common and machine-readable format”. Wonderful. But mostly you can only export the data, but not upload it to the new service and import it there.
In order to get around this annoying restriction, a number of apps help with the transition from one sports world to the other. SyncMyTracks is available for the Google operating system and can be tried out for free. Then a maximum of 40 of the latest trainings will be copied from one service to another. The full version for three euros does not have this limitation, you can have all activities or those of a freely selectable period of time. The basic information is transmitted without any problems, but the problem lies in the detail. Be it that the sports are called differently in the new service, or that calorie calculations and other statistical evaluations are incorrect. So you have to go to work carefully and don’t expect everything to work perfectly right away.
Several small details did not come with me
In the Apple world, we tried Run Gap, which offers similar functionality, but only works fully if you take out a subscription that costs 4.50 euros for three months. After that, the imported data can be passed on to a few dozen sports services. The in-house Apple Health can also be addressed. When running, the app took over the route including the map, the heart rate display, the pace, the step frequency and the altitude profile of the route. The basic data was also perfectly adopted for cycling. However, a number of small details did not come with the move. This is not surprising either, because the manufacturers of sports watches distill their exclusive content from the raw data, such as information on performance, the calculation of maximum oxygen uptake and other things. Nobody wants to publish their formulas, according to which the athlete’s training condition, recommendations, indications and other parameters are calculated.
One of the most interesting new releases for exporting and evaluating training data is the iPhone app Health Fit by Stephane Lizeray. It costs 4.50 euros one-time, does not require a subscription and uses the sports and health data of the Apple Watch. She does it with flying colors, and the French developer is constantly developing his software. First you can export all training data like with the competition, for example to Komoot, Suunto, Strava, but also to cloud storage such as Dropbox, Google Drive, Onedrive and others. In addition, such an export can also take place automatically after the end of each training session.
Health Fit then evaluates each workout. In the representation of a racing bike tour you can see graphically the heart rate, speed and altitude superimposed and the heart rate recovery values after the end of the training. Health Fit calculates the training load and shows the times in the various heart rate zones. This is how you can tell whether you have tormented yourself too much – or too little. All of this is well done, but it gets even better in the second statistics module. Here you can motivate yourself for hours, for example when you see how many calories were burned per month compared to the previous month or how many kilometers were accumulated per month. The whole thing is then also available for the course of the year and in an overall statistic that draws on all the recordings of the Apple Watch. So you can quickly see how successful the sports year has been so far.
Finally, Health Fit also evaluates the health data of the Apple Watch, for example with a display of the resting heart rate or heart rate variability over the time axis. The app is easy to use and almost everything is self-explanatory. If we could only recommend one sports app, it would be this one.
