Not bad-does the basics

I ran a sprint Tri today and figured the short event was the perfect place to test the app. It functioned fine during the race (no trouble with buttons or the app changing from one event to the next). My activities where appropriately logged in my Apple Activity App but in the TriTracker app, all of my time is in the “transitions” and no distance is showing up in the events (which is odd considering it logged them accurately in the activity app). The other thing I noticed was that my swim wasn’t mapped (something I normally get out of the open water swim function in the activity app)... certainly doesn’t replace a Garmin but for those who want to own a single watch and like Apple’s activity app, it’s not a bad option. I’m sure the few small glitches will be worked out. For now it does enough to be a functional option for those wanting immediate feedback after a race and to log their race activity with their training.

It’s a dud

I did a dress rehearsal for my Olympic-distance tri and used the app for the first time. It didn’t correctly display the distance during my swim, then after pushing the two side buttons for T1, didn’t display the transition time. But when I pressed them again, it started the bike segment. Even worse, at some point during the bike, without any notification, it gave some error message and said it had started a new workout, though it appeared not to have done so. Needless to say, I didn’t bother with it for the run (and was glad I had also been using Cyclemeter on my phone for the run).

After I finished, the phone app shows no recorded data for anything. Fortunately, it at least imported the swim segment into the Workout app on my phone, so I have can view the data there, though weirdly not in the Triathlon Tracker app.

The whole experience with both the phone and watch apps is garbage. If I can’t trust it to work as promised for a workout, there’s no way I’m going to take a risk relying on it for a race. I’d really like the developer to refund my $9.99.

Did the job, still some bugs

Just got done using this app for the first time in a race, I did a sprint tri. I had issues with it freezing up while testing it out for a swim/run training, and I actually had to restart my watch to get it to open again. This morning before the race, it again seemed frozen and would not open. I had to restart my watch, and then it opened and it worked! I think it was freezing when I would get a text and it didn’t know what to do. I do not have cellular on my watch and I was not close enough to my phone during the whole race to pick up texts, so I think that is why it managed to not freeze during the race. Hopefully some of the bugs can be worked out, because I loved FINALLY having an Apple Watch tri app and I hope to continue using it!
