@Dimitrios-Kanellopoulos Then everything is all good . Thanks.

@DRezvoff The image you posted is from Strava. Strava will change the elevation data for non barometric devices as well, so comparing from Strava is probably not the best. From the links you sent only the Suunto 9 (non baro) and Spartan Sport do not have barometers assuming the one marked Garmin also has a barometer. The two without barometer show the greater deviation. However, your watch is showing poor readings, worse than I would expect.

@s0flyc which watch?

@martin exactly

What is your problem? Watch doesn’t connect with suunto app? If so check this https://www.youtube.com/watch?v=Hg5luY_wuAU or this for android https://www.youtube.com/watch?v=Y4cCukrEOg8

@thierrymichel probably an issue with the maps in your region as mine is working.

@RobGR i dont know as well. Took a good look at the raw data of the file and could not find anything bad to be honest. But saying this because other apps had their own quirkness there. Perhaps 1 wrong timestamp? No clue

@pavel-samokha Now works fine thanks a lot 🤟🤟🤟

@omunoz Good as I am having no issues on iPhone X…waiting for the 12 to be announced, I need a new phone.

@Brad_Olwin Thank you for your response. I tried doing what you said and still get all or none. Not sure if there is a specific threat (that you can share) where this is explained. What you mean that it is controlled at the iOS level, that Suunto has no way to fix this?

@gordfriesen Do you have also forgotten in the watches themselves? In menu, connexion, device paired, forget mobile app.

@Uwe-Wt die Synchronisierung mit der App sollte auch über BT funktionieren. Es gibt verschiedene Gründe, warum das bei einigen Aufzeichnungen fehlgeschlagen sein könnte. Es ist z.B. wichtig, das weder Telefon noch Uhr in den Standby-Modus gehen während der Synchronisation. Gerade wenn es beim ersten Mal evtl viele Daten sind, kann so etwas passieren. Am besten noch einmal probieren, wenn eine neue Aufzeichnung dazugekommen ist.

@Efejota then maybe the app calculates elevation on the fly?

@nseslija told you
