Sometimes less is more; sometimes you just need to get your training done without all the fluff. Without the fancy virtual reality, the TV's, the charging cables, tablet stands, and the cluttered setup. Sometimes you just want your bike on the trainer, your phone to control it...and some music or a movie.

At the heart of any good training program is interval repeats. Zone CTRL is an app for your phone that makes building & executing interval-style programs a breeze, and in a matter of seconds! You can get on your bike and while warming up key in the program your coach has given you. Or make one up on the fly.

Maybe this week it's 16 x 1-minute ON/OFF, and tomorrow it's a 3-step pyramid, repeated 7 times. And next week it's the exact same thing but with just 1 more repeat. No more saving, editing, duplicating & renaming structured workouts just to enable a slight change. With Zone CTRL you simply plug in a few values and away you go!

If you're lucky enough to have a coach that creates structured workouts for you (nice!), in TrainingPeaks for example, simply export the ERG or MRC file to your downloads folder then load it up to Zone CTRL. Hit play and get going.

Zone CTRL has the following features:
--------------------------------------------------------------------
- Connects to bluetooth-enabled electronic smart trainers that follow the FTMS standard (most modern trainers from 2020 onwards, and many prior).
- Stores your current weight (in Kg) and FTP (in Watts).
- Controls your trainer in ERG mode (i.e. Watts).
- Controls your trainer using Watts per kilogram (W/kg).
- Controls your trainer using % of FTP.
- Controls your trainer by Power Zone. (Z1-Z6, low, mid, or high).
- Controls your trainer in Resistance mode (i.e. 0-100%).
- Flexible control of the number of steps/repeats while in a workout.

Zone CTRL has the following screens:
--------------------------------------------------------------------
- Free Ride - simple screen to set a target that you can increase/decrease easily with a number of preset values to change between.

- Manual Intervals - a screen with 2 configurable targets that you can easily swap between, with a single button tap.

- Auto Intervals - configure 2 targets & durations that the app will automatically swap between. Repeat as many as you choose.

- Ramp - configure any number of ramp/steps, incrementing from a starting target for your chosen duration. Repeat "the ramp" as many times as you choose.

- Pyramid - similar to Ramp, but the series of steps comes back down to the starting target. E.g a 5-step ramp would be 3 steps up, then 2 steps down. Repeat "the pyramid" as many times as you choose.

- Under/Overs - set a target value and let the app control a curved under & over pattern for a given variance, e.g. target 200W with 10% variance gives a peak of 220W and a trough of 180W. Repeat the pattern as many as you choose.

- Structured Workout - imports the ERG or MRC file format from another system so that you can easily ride a pre-created structured workout.
