Tired of carrying a gear chart to the velodrome every day, or searching the web for one every time you change gears? Then you need a gear calculator on your iPhone and your Apple Watch.

Built by track racers for track racers, the Track Gear Calculator supports chainrings from 44 to 56 teeth and cogs from 12 to 20 teeth. It includes a speed/cadence calculator, and can calculate the next gear up or down using only the gears in your track bag.

Want a bigger gear or a smaller gear? Track Gear Calculator works in reverse, too: just swipe the gear inches, and you'll get a new gear, up or down from where you are, using only the chainrings and cogs you have with you. You can also select from the standard 27" nominal method for calculating gears, or more accurate actual wheel diameters, and you can see results in either Imperial gear inches or Metric development.

What’s New

Version 2.10

The Jonathan: Better support for smaller devices and larger typefaces.

Beautiful App, please expand range

This app is very nicely executed, and I get that it’s intended for track cyclists, but simply make the gear ranges larger and you have a Five Star App.

There is not much to say here, the app is very bare bones, but in the best way possible. The interface is very slick, and does exactly what you want to do with great ease. I really enjoyed the simplistic, minimal user interface. All of the options in the settings menu give you everything you need from the type of measurements (imperial/metric), to their where you marry you speed (mph/kph).

I highly recommend this app for being one of the best and easiest to use gear ratio calculators.

The only thing this app is missing, and it might be because I'm blind and didn't find it right away, is a skid patch calculator.

Could be so much better

Great concept, simple gear calculator to remind me of my gear options.

Please tell me why the Apple Watch version does not take the chainring/cog preferences from the phone app setup?

The watch app is useless without that feature.
