iMobileIntervals (iMi) turns your iPhone or iPod Touch into a powerful cycling or running computer.
iMi supports collections and display of data from ANT+ wireless sensors, such as heart rate monitors, stride sensors, speed/cadence sensors and powermeters.
iMi connects you to your personal workouts, daily workouts in iMi training plans or your 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 imobileintervals.com, run in your iDevice using your ANT+ sensors, then analyze your results.
