## Gear Ratio Calculator Lite Description
This application calculates gear ratios for the road bike and the MTB.
Combination of 22 types of chain wheel, 39 types of sprockets and 70 types of tires - Create a graph of the gear ratio and speed-cadence.
By switch ON/OFF the display of each inner / center / outer gear, you can simulate the optimal gear ratio.
This application helps you to choosing a satisfy replacement parts.

--------------
This application allow the simulation of the gear ratio in the four charts. 

[km/h RPM]
[mph RPM]
[m/s RPM]
Create a praph, the speed (km/h, mph, m/s) values will be displayed on the vertical axis, and the cadence (rpm) values will be displayed on the horizontal axis.
This graph can be displayed the changes of the speed for each position of the gear in revolutions of the crank.
The gear ratio to match the speed range you want, while viewing a graph, you can simulate a combination of parts.

[Gear Ratio]
Calculates and displays the gear ratio from each position of the selected chain wheel and sprocket. 
Increases the burden on the foot when shifting between long distance between points on the graph, the smaller it is close.

[Gain Ratio] 
To caliculate and display the distance run by the crank comes full circle.

## Gear Ratio Calculator Lite Reviews in United States

### *---- "App closes when any button within settings is touched."
The app will not allow any changes to the preloaded ratios, it won’t allow you to upgrade from within the app either, It will crash, or close upon button press.
-- Paper work challenged, 2025-09-01

### **--- "Outdated, doesn't support 12 speed cassettes"
Very simple cadence/speed graph. Useful, but doesn't have 12 speed cassette support.
-- Carlos from Philly, 2021-06-22

### ***** "Very useful"
Was able to enter custom rings and cassette from an older MTB as I'm shopping for a different cassette, and this app works wonderfully. Only flaw I found so far is that the Gain graphs seem off, probably because it doesn't have a setting for crank length. I'm basing my decision mostly on cadence though, so gain is just a curiosity really. Thanks for this app!
-- headquire, 2019-06-08

### *---- "Useless"
No place for user input
-- Vasqi, 2018-01-24

### ***** "Excellent gear calculator"
I have used this to compare 1x11 , 2x11 , 3x10, and 2x10 Mountain bike gearing for 29, 26 and 650b wheel sizes.  It really helped me understand what the gains and losses were with different solutions.  I hope they update the app so it will work with the next release of IOS. I would even pay to upgrade this app.
-- djnikel, 2017-04-27

### **--- "Needs improving"
Needs explanations and chart display in addition to the graphs.
-- Qwerty zzz, 2015-12-11

### **--- "Poor gear selection."
The graphs are great. However, they are useless if you can't add your own gear size and many common sizes are not available. The ads integrate poorly and cover the graphs.
-- Pat McGroin173, 2013-11-12
