Intervals Pro: HIIT Timer

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".

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.

I was once a D1 athlete a long long time ago. I then took a 6 year hiatus from all things cardio... and when I decided to get back into running again I knew I needed a straightforward interval timer to help me with my couch potato to 10k program. After reading some reviews I decided to purchase the full version of intervals pro and I am so glad I did! It’s so easy to make unlimited timers, the interface is straight forward and works phenomenally with my Apple Watch and iPhone, and I’m going on 5 weeks of using this app and running again after 6 whole years of no cardio activity! I can’t say enough good things about this app. If you’re hesitant to purchase, think about it this way. You spend more on a fast food meal and this is way better for you in the long run 😉 that helped me take the plunge. Go for it! It’s a great app!

I used another HIIT timer for my Couch to 5k before this app and haven't touched it since downloading this one. Intervals even has its own timers built in so you can just use their template. Very thoughtful. The Apple Watch integration and the built in distance tracking meant I didn't have to bring my phone when running while using the timer. I mention this despite it seeming like a given because the other timer app I downloaded didn't support it. The only gripe I have, if any, would be that I want to be able to see the day's workout beforehand on my watch. As it stands I need to use my phone or start the timer to do so. Also, when running, it says how many intervals are remaining but I'd like very much like the option to have something like ⅜. Overall, fantastic app and a real game changer for someone like me trying to get up and move this new year (little late I know). For the fitness enthusiasts or people actually planning on using their Apple Watch for tracking workouts, I highly recommend it.

I really love this app for its simplicity, usefulness, and customization. It’s easy to set up whatever type of timers/workout intervals I want and I love that the voice commands can be whatever I want. The halfway and 5 seconds left capabilities help motivate me to keep going. My only complaint is that the background screen has changed from black/charcoal to white in this upgrade. It hurts my eyes in the early morning darkness when I run. Being able to set the background screen color/display as an option would be fantastic. It would also be nice to display the time (clock time) slightly larger. It can be a bit hard to read when you’re running. Thanks for creating and maintaining this app! (PS it would be nice to post a review without having to make up a nickname all of which I might choose have already been taken!)
