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.

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.

Worked great for Olympic Tri!

I used this app for the Southbeach Miami open water Olympic distance triathlon on April 15th, with my Apple Watch 3 with LTE.

It worked great! The double button press to transition between tri legs was simple and worked as intended. Tri Tracker did a good job tracking all legs of the triathlon with GPS, even the open water swim. I had no Apple Watch battery issues using the app for the duration (3+ hours) - it kept plenty of charge even with LTE enabled the whole time, and several texts coming in along the way.

As far as the user interface goes, the basics worked, but a few display tweaks would perfect it. It was a bit of an issue that there’s no way to view stats on the watch itself for a completed activity without having an iPhone handy. Also the run stats were a bit hard to read during the run itself, so it would be good if text size and location on the watchface display could somehow be configurable in future releases.

Overall, though, very happy with this app! Much better than using the built in Apple Watch capabilities for a tri. Hoping the developers keep working on this because this is exactly the functionality I’ve been waiting for and I expect there’ll be big demand from the tri community.
