iMobileIntervals (iMi) turns your iPhone or iPod Touch into a powerful cycling or running computer.
iMi supports collection and display of data from wireless sensors, such as heart rate monitors, stride sensors, speed/cadence sensors, powermeters, the Magellan Echo/Echo FIT watch, the Wahoo RFLKT remote display and KICKR trainer.
iMi connects you to your personal workouts, daily workouts in iMi training plans, your Garmin Connect workouts and calendar, CadenceTV account, TrainingPeaks (and Affiliates) Calendar, workouts you share in your iMi groups, and iMi public workouts.
iMi allows you to create interval workouts right in the app, no website required.
TrainingPeaks workouts can be converted and run in iMi, or paired with an existing iMi workout. Results are sent to update your TrainingPeaks workout.
With iMi it's just automatic: plan your workouts in TrainingPeaks or at, run in your iDevice using your sensors, then analyze your results.


Intervals. Sensors. Telemetry. AppleTV. ERG workouts. Voice prompts. Data to the cloud. iMi has it covered.


iMi is on the Appstore! Get it today and take your intervals training to the next level.
