Ratings and Reviews
Helping me get back into Running!
This app is highly customizable helping me get back into running. It would be great if the app could capture elevation data and weather from the Apple Watch like the Apple workouts do, also pass split information and display them in the Apple Fitness App. As for timer customization it would be cool if countdown alert and countdown haptic were nested under the interval and rest sections so you could for example have an alert prior to a work interval but not an alert prior to the rest interval. Display customization requests include. Give the user the ability to turn off the GPS strength indicator on the watch display. Possibly add a 6th line item to the watch without having to swipe to another screen if using an Apple Watch 7. Add steps as a metric pulled from the Apple Watch. I’m not sure if this is possible for a non Apple workout app but when you leave the app it doesn’t go back to the workout without manually going back to the app, on an Apple workout it goes back to the app automatically. Another thing is possibly creating some different app icons so users can customize the app look. As for any issues I’ve seen. I only use the Apple Watch version of the app when working out and I have seen where the Apple Watch is dropping saved timers from the view prior to starting a workout but I fixed this by forcing the Apple Watch sync from the app.
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 is an excellent app!
If you want to set up your own custom intervals. I’ve bought it twice just to support the dev, who’s very responsive too. I gave it four stars only because at the moment, there’s no way to batch delete the workouts and deleting them one by one takes way too much time, when it really shouldn’t. Once that’s been updated, I’ll straight up change it to five stars. Other than that, it integrates excellently with Apple Watch too and it doesn’t force you to use the app to track your workouts either. You can set it to just time out your intervals and let any other workout app you want to use track your workout instead. I don’t use the option at the moment, but I definitely thought about it, and was pleasantly surprised it was available. It’s excellent. You definitely won’t be disappointed.
Edit: I don’t know when it happened but batch delete is now in. Excellent app. I just hope it doesn’t go subscription now otherwise this is just excellent for anyone wanting to start running (or if they just want an intervals app!). 10 out of 5 stars!
