Note: Continued use of GPS running in the background can dramatically decrease battery life. However iMi only uses location services when a workout is actually in progress. Live telemetry and route tracking rely on GPS, but location services can be turned off and still successfully use the interval functionality or any sensor-based functionality in iMobileIntervals.

Reviews

Straightforward
Snookanglr

I've been using this app (and the website) for years and nothing beats it for simplicity and ease of use. Create your own interval workout or use one of public ones. There's hundreds if not thousands of them. I use it with an iPhone 5 and a first gen Wahoo Kickr. I've had zero problems.


For advanced cyclists!
Bellullabob

The interface can use some polishing but superb in that u can really design very complex interval sessions.


Great workout tool
Georover33

This application is my new coach!!!!


Works well if not interrupted.
WorkoutPerson

The app works well if it is not interrupted by something else (eg phone call, IM, etc). However, if interrupted, it sometimes stops recording time but seems to continue recording GPS coordinates. At the end it will log the full course to Trainpeaks but the abbreviated time. (even though the full workout time is recorded at the end) This definitely needs to be fixed

This app is really cool. The telemetry feature really sets it apart. My friends and coach can track my rides and see my power/heart rate in real time. Badass! Wish it could run in the background, but Apple won't let it. I use an ANT+ stick from Wahoo. Cool technology, great app!


Wont launch
Vieroski

The application won't launch on my iPhone 4. I see the intro screen for less than a second before being sent back to the home screen. I've closed all other applications, tried restarting, tried with and without the Wahoo ANT+ dongle, tried turning on and off various radios, just about everything I can think of to get this thing to work. Finally decided I'd check out their website, but that too is down. Managed to use Google Webpage Archives to see an old copy of their site but couldn't find any support contact info, only a forum. I plan to keep an eye on their site in hopes it will come back up but I am not holding my breath. Hopefully their domain name records are public and I can do a whois and contact someone that way. Super let down though, I am leaving for gym in about an hour and have really gotten tired of the interval features on my watch. Features like those supposedly on this application were why I bought the chest strap for the iPhone in the first place.


Works great with the KICKR
herothedog

Just got a Wahoo KICKR for winter training. IMI works very well controlling the power of the KICKR resistance for consistent interval workouts. The KICKR power measures about 10W higher than my SRM, so being able to use a Watts offset helps keep the data accurate so when winter is over and I can do intervals outdoors again I shouldn’t feel like I was cheated over the winter months!


Great little app
Drpleishner

Not as polished as big players but handles everything you throw at it just fine. I use it to work out with Wahoo KICKR, I hooked up Wahoo RPM cadence sensor too. It's the only iPhone app I found that can do interval training. It has large library of public workouts, including ERG workouts for Sufferfest videos.


Issue with v3.2
Mnpjr

Can't enter user id's In either the Garmin Connect, or the imi fields.


Super for running too!
Samd5280

This app is brilliant with intervals. Nothing else like it and really rocks the KICKR trainer in ERG mode. And now I can get the interval workout display on my wrist for runs using the Magellan Echo watch! So great! Also, the iOS7 update had a bug with the user logins, but they fixed that right away.
