Successful (and tiring) day testing Pedometer++ today. My big focus is trying to reduce battery usage to extend the maximum possible session. I've gotten this down to around 9% per hour (on my year old Ultra 2) for a fully tracked, map based workout, which is reasonable but still a meaningful leap from my goal of 4% (which would allow for a 24 hour expedition).

But I still have loads of ideas for things to try and think it should be possible (Apple quotes a max of 35hr for their workout app).

Another successful day testing Pedometer++ in the mountains. Last night’s work I did on battery life paid off a bit, down to 8% per hour, but still work to be done. Think CoreLocation is the next frontier I’m going to need to optimize for.

Though I can’t think of a finer day for hiking/“testing”, gorgeous sunshine on snow covered fells, will unlimited visibilty. Just about warm enough to be comfortable. And barely a soul around so felt like it was all for me.

Had a breakthrough in my ongoing quest to build an Apple Watch map based hiking app which can last for an entire 24 hour expedition today. Too early to know if it will be repeatable, but my new approach is down to around 4% loss per hour which would get me to where I need to be.

I really enjoy this kind of work, where it feels very much like exploration. I have no idea if what I'm building is possible which is far more interesting than the more typical work of turning “JSON into TableViews”.

@_Davidsmith Lately I’ve been referring to the typical type of work you mentioned as “JSON herding”. Everyone I’ve mentioned it to seems to understand what I mean even if it’s the first time they hear the phrase
