Lately this app has been crashing my phone. Also, the whole constant insistence on always “calibrating” really gets old. It has trouble detecting and accounting for obviously nonsensical GPS data. I use it religiously however (well, used to, because now it tends to force reboot my phone in the middle of all my walks). It’s indispensable and offers a great service (when it works). I do think the animations when you’re switching routines are extraneous though. I prefer instant results to fancy transitions, particularly when I’m about to engage in exercise and am fumbling my phone out the pocket and need it to fire up right away (and if the calibrate dialog comes up in that situation I get pretty unhappy… just start tracking and self-calibrate when the signal improves… these are standard streets and trails we’re on out here… not hard to figure it out. Turn-by-turn GPS navigation never has these problems or hangups.)
