Cycling Calculator

DY Software

About this app

This is an essential app for an everyday bicyclist to a professional cyclist. This app has it all! Many calculations including Gear Ratio, Gear Inches, Meters of Development, Gear Speed and Skid Patch. There is also an all inclusive table that calculates all of the combinations of rim and tires to wheel and wheel circumference. Try different gear possibilities, or find out what cadence at a specific gear will produce the speed you want. Check out all the information possible on specific gear combinations. Also, compare different chainring/cog possibilities side by side by the innovative storing of the last 5 chainrings used. This app supports many chainring, cassette/cog, tire and rim sizes. This app can save you valuable time and money by trying different gear combinations to setup the bike how you want it. Newly added, estimations on speed and power. Estimate your speed based on a variety of configurable variables including power, weight, temperature, elevation, rolling resistance, wind, grade, frontal area drag and efficiency. Great for trying to estimate times for triathlons and races! Figure out what speed or power you will need for a specific distance. Even calculates calories and weight loss.

1. Added new estimation screens that you can key in all of the relevant data. This gives what people have been asking for of decimal values for estimation calculations.
2. Various bug fixes.
3. Fixed rotation issues, all screens should now fit a rotated screen.
4. Various rounding and calculations were fixed with the addition of the decimal for estimations.

Ratings and reviews

It would be nice to see a choise of speed in the "gear calculation" menu. In "gear speed" as well, a choise of speed and cog's settings. I don't have a cadence sensor and I don't think many cyclists have one but everyone has an app or a bike computer indicating speed which then can work out the rest. I used to use 'bike gear calculator' but for some reason I can't find it anymore for my new phone. Anyhow this is a a good working tool but it limits me not be able to choose speed and set my own cog set only.

Just wish the app was updated with a better UI

Love this app for working out single speed and 1x10 ratios. But it needs to be brought up to date with the recent 36, 40 and 42 tooth range extending 1st gear cogs.

What's new

Completely redesigned to fit all screens. Bug fixes and faster!

Per request, increased the cogs to support up to 42.
