This is an exciting release for home trainer users. Now you can use the $30 Chromecast to display your workout on any TV with an HDMI port.

iMobileIntervals integrates with YouTube to provide video content behind the workout. Several default playlists are provided and you can add your own playlists. Individual workouts can have their own video or playlist, set in-app or on the website.

On your TV, overlaid top and bottom on the video, you get:
* interval count, graph, now/next caption, elapsed and interval time
* interval change countdown
* sensor data (hr, pwr, cad, speed)
* normalized power, intensity factor, TSS

More love for the WahooFitness KICKR in this release! ERG/MRC files contain data to control the resistance of the KICKR trainer, and while iMobileIntervals.com has had an ERG importer feature for some time, converting ERG/MRC files into iMi workouts in your Personal Workouts library, you can now send ERG and MRC files direct to the app.

The file must have a .erg or .mrc file ending, and conform to the standard or PerfPro ERG format (however distance and slope intervals are not supported).

How to do it:

In addition to being built with the iOS 8.1 SDK, iMobileIntervals gets some good tweaks in this edition:
