I have been using Run Tracker for abut 3 years pretty much without issue from iOS 6 to (the current) 8.4. Don’t recall any crashing in that time and I’m not anal enough to quibble over any minor irregularities in precise distance measurements. If anything, it has underestimated distance.
The only current issue with this app is that under iOS 8.4 the built-in music player trumps the Music App completely ignoring my customized Shuffle. I won’t knock Bluefin for that since there hasn’t been an update post-8.4, but this is something that should be addressed in the next revision.
Overall, I am very pleased with this app.
