## What is Track Gear Calculator?

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 70 teeth and cogs from 8 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.

## Key features

- Chainring and cog size support
- Speed and cadence calculation
- Calculate next gear up or down
- Reverse gear calculation
- Standard or actual wheel diameter options
- Imperial or Metric unit display

### 5/5 — Favorite App

*2025-07-18*

I am using this app on the track and off the track to plan and choose right gear for the race.

### 5/5 — Nice app

*2024-11-22, version 2.20*

Amazing app using already many years

### 5/5 — Повод для обновы

*2024-05-27, version 2.20*

Отличная приложуха, но уже давно существует 21 и 22 звезда, добавьте)

### 5/5 — Made by a track cyclist for track cyclists

*2023-11-18*

App made by a track cyclist for track cyclists.  Does exactly what you need for track racing with a few nice touches to improve usability, like selecting gears in your kit along with swipe up down to find your next largest or smallest gear.

### 5/5 — Добавить

*2023-09-05, version 2.10*

Добавьте пожалуйста все возможные альтернативы по звездам , чтобы получить например определенное число в дюймах.
Например: мне надо передачу 115.9 это например 60*14 , но можно еще поставить 56*13 или 64*15 или 69*16 (-+ варианты)

### 1/5 — 为什么没有小盘数据出来

*2023-02-20*

30T或者以上都应该整

### 1/5 — Not for MTB

*2021-03-24*

Very limited range of gears. Not worth buying

### 4/5 — Beautiful App, please expand range

*2019-12-19*

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.

### 3/5 — Great app with limitations

*2019-10-21*

The program only goes up to a 56 tooth gear on the chainring. With the advent of larger chainring and cog combos being used on the track today, the program should at least offer up to a 60t. This would be great to see in a future update.

### 1/5 — Can't install to Watch

*2019-05-11*

Please update the app for WatchOS 5.2 and Series 4
