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".

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.

Love this app - five stars plus!

I never review apps, but I tried this app for the first time tonight - oh my God it's awesome. I wanted an app that would time walking/running intervals for me, but also alert me via haptics to when I needed to switch back & forth (2 min walking, one minute running). This does that - and it alerts you when halfway through each cycle as well as giving you a five second countdown before switching. It's totally awesome and tracks into everything I already have seamlessly as well - I wanted an app that would work with my Apple watch , Apple heath & Oura. This does that. I had been doing periodic interval running on a treadmill, where you can see and control the intervals - but this makes outside interval running easy. Kinda. You still have to run, and without the treadmill to pace me, well - it's different. But really another fun alternative to just running two miles a day as fast as I can. Free to download, but to customize the way I did you need to buy the upgrade. $8.95 + tax well spent :)
