Ratings and Reviews
Love, must have
I absolutely love this app. Finding an interval app that is so customizable is hard, and I've tried most out there. This app supersedes all other apps out there, it is super affordable, and the summaries are great. It shows total time, active cal, distance, avg. pace and heart rate. It integrates smoothly with health an the activity rings on the watch if you use that. Also, fully functional on the watch only. I don't carry my phone so finding an app that worked independently was imperative and this one does.
On another note, I had an initial issue when I first upgraded to the paid version where my distance, calories, and avg. pace were not showing in my summary and the developers/support staff not only responded to my email within hours, but walked me through different solutions. I realized that it may have been that I tried using it rather quickly after the upgrade and it possibly took maybe 12-24 hours for the app to fully get to its potential and upgraded features, so I count that as user error, but nonetheless the quick and great support set this above the bar for my standards, so much so that I decided to write my first and only app review and I've been an avid iPhone owner since the first release.
Big thanks to Jeff Bailey, you're an awesome person for this brand, either as a rep, support staff, coder, or creator you've got me hooked and hope to see more from you guys at "Intervals".
This app was recommended to me before I even bought an Apple Watch. Intervals is a phenomenal app for any runner, but especially a runner that does a run-walk routine. I use it for overall distance, time, route, and pace. I really like that after saving the workout, it breaks down average pace for each interval. That shows me when I have slowed down or sped up. I had many questions when I first started using the app and the support is just as good as the app. Almost every single email with questions was answered the same day. I was so impressed with the support that I thanked them in an email. Purchase this app, the price is reasonable, and you will be very happy with the functionality of the app.
Update: After using this app for four months, I still think it’s an incredible app for a great price. I have recommended it to five people (3 have Apple Watches) and they all love it.
Update after WatchOS 5.0.1: There was an issue after the watch update. I emailed the developer after two workouts and he was already working on a fix. Within two days, it was fixed through an update. But I had a few more questions and emailed him again. As always, he replied within a couple of hours. It’s not only the app functions that makes Intervals the best choice, it’s also the amazing support.
Now one of my core apps
We all have a group of go-to, well-designed useful apps that we can’t get along without. Intervals now falls in that category for me. I had been using another HIIT timer for many years. It was very simple and did the job, but offered only basic functionality. Intervals is a giant leap forward from that. One of the main reasons I bought it was for Apple Watch functionality. The great thing is that I can listen to music from my iPhone through my Bluetooth headphones, start an Intervals timer on my Apple Watch, and then listen to upcoming alarms through the headphones. The remote mode for the Apple Watch is truly magical. It also allows me to shut off my phone and put it safely in my pocket while working out allowing me to use my Apple Watch to monitor progress of my workout. Also, the post-workout breakdown of data by work and recovery splits is incredible. BTW, I have the Pro version which opens up a full range of functionality, and more importantly allows you to compensate the developers for this excellent app.
