Yeah, I'm still seeing nothing but zeros for Time/Walking Steps. I went so far as doing a factory reset on the watch and re-installing UpTempo. I can still get sleep to work (i.e., set the watch on the desk and it is recording that time as sleep), so it's running in the background okay (had a watchface up).
I'm using an older Pebble Steel if that makes a difference. Have the latest firmware update for the older OS.
I don't know - maybe the tweaking you did had a bigger effect than expected considering the way I use the app. At 65, I'm not what you would call an aggressive walker. When I walk it's less than a mile at a time and most of the time walking the dog, so my pace is pretty slow (as in the dog makes frequent stops). Let's say I cover a half mile in around 25 to 30 minutes (although it's uphill/downhill where I live so the pace is not constant). It seemed like prior to v.9 it was tracking steps/time pretty well whenever I walked more than, say, 5 or 10 minutes straight and didn't add any significant steps when I got up to fill my coffee cup or just move around for a short while).
That may not be what UpTempo is intended for. If that's the case, I'm okay with that and certainly don't want you to change that model. I've used Misfit, but it seems to add way too many steps (I can get hundreds of steps just by typing at the computer - if I use it for sleep tracking I wake up with the app showing 600 steps that I took while I was asleep!). I've used Up for Pebble and it's okay (does a better job of tracking steps) but what I like about UpTempo is it also shows accumulated minutes of activity. Yeah, I can back-calculate minutes based on steps and a pace guesstimate, or I can use a stopwatch to time walks, but neither of those is a great solution.
Anyway, I don't want to create more work for you trying to make the app fill a use case that is too far outside it's intended user base. I can get by just fine with something like Up for daytime and Misfit at night (or Misfit for both if they ever get the step counting right).
