I’m too kinda afraid a little about the whole servers go down and everything is ending eventually thing. But to be honest, there will be ways to put software on the watches and if needed, even new firmware. Maybe cloud stuff will live on in a different form and maybe the activity tracking can be improved a little. It all depends on the community.
As for the wrong calorie value. The pebble don’t track activities strickt enough to know if you run, roll or just fapping. Also it waits a long time before it sense the end of an activity - I think this kinda doubles the numbers (with the below explained mechanic).
Now, even if we don’t count these problems, the numbers you see are not really the values the watch records. It’s more like an avarage of the previous days - so the inaccurate readings aren’t showing that messy.
Btw, if you try to get the readings real-time you will see a lot of 0s and some probably cumulated values that can change over time like if it’s lagging with processing.
Personally, I couldn’t get it to count anything reasonable. Also more accurate activity trackers will need you to input the kind of activity you doing and make you start and stop tracking, so they have a much easier time doing calculations.
If someone is interested - and has the technical knowledge and the wills - in keeping Pebble alive as a homebrew community, do it! And let me know if I can help!
