Say I use Garmin Connect Mobile iOS to look at a 43 minute run activity (track interval workout) over 5.91 km, with 1-second recording.
If I hold my finger over the pace graph and drag left/right, I only can see data at a "resolution" of 10 seconds. No matter how slowly I drag my finger, I only see my pace at intervals of 10 seconds. The funny thing is that if I zoom in by pinching, the same limitation applies. I can't see data that's any more detailed. In the same way, the graph doesn't get anymore detailed when I zoom in.
In contrast, for the same activity on the Garmin Connect website, I can roll over the pace graph and I get data at a resolution of 2 seconds, even without zooming in. Although, of course, it's a lot easier if I do zoom in, as I don't need to roll over quite so slowly to see the data I want.
It's really nice to see that extra detail, but it's too bad we can't get it in the app. It seems like it wouldn't be impossible for zooming in to actually reveal more data, instead of just blowing up the graph.
Just continuing the trend of a mobile-first world where mobile apps can actually do a lot less than websites.... It doesn't have to be that way, but I get it.
I don't expect this to ever change, but I'm just putting it out there in case anyone else has had the same experience.
