Gear Speed Calculator

Thank you for making this! It helped me see the difference in top speed between my 18" wheels compared to my 15" wheels.

Super

Useful

I use this all the time. It is a perfect tool for people who want to work with changing gearboxes,autos, wheel sizes, diff ratios. Love it.

Great job. Help a lot

Works great

Yup doesn't work for Note 4. Only has Nissan gears... Pinch to zoom don't work. Uninstall !!!!

Ive already paid for this app why are you trying to charge me again for it , it wasnt sold as a subscription app

My big complaint with this app that I can see... you got to use the phones menu button to be able to change some things.... I have a Galaxy S5, it doesn't have a menu button... also more gears are needed. Looking at putting a over drive splitter box behind the Trans in my truck along with going from 3.42 to a 4.56 gear, so it would be an 8 speed.. it's a good app but with a few tweaks it could really be something... the graph could be much bigger. I can't even see the numbers

Mcm2..

Works awesome. Just needs updated for the number of gears in new vehicles. Might as well make it a 10 gear calculator with the way automakers are headed.

Easy to use...

It won't let me input any specs

Great app' we run RB25/30 with standard GTSt gearbox at present, this will be very useful to allow us to chose rear ends to suit different tracks, also we are looking to change to a 4 speed, probably a M21/M22 Muncie. It would be better if I could enlarge the page on my Samsung S3 Mini There is a difference between the App and the website, In the App there is only one diff ratio which is the automatic one 4.3 and the gear ratios are all for the same gearbox FS5W71C which is the small gearbox

Ideal for all forms of motor sports and road setup s as well, if this app had more preset gear ratios from other oems available to download it would be great

Doesn't have my ratio or tire size. .. incomplete.

Cheers mate.. works great!

Works great fella!

The best.

Please add smaller rim and tyre size. Thanks :-)

Great for bracket drag racing. If you don't know what that is then don't bother it might confuse you. I love it!

I was really impressed with how accurate this program was, gave me really good data that almost matched my land speed numbers

Simple and effective. It is accurate. I would have given it 5 stars but I feel it needs an option for 8 gears like my car has.

Very handy. Should add a zoom function when viewing the graph and maybe a third combination to compare. Thank you.

What a superb application... planning for race events has become even easier on the go.

Works pretty well, and I like being able to compare the graphs, but I can't delete any of the stuff I've added.

I need to be able to manually enter in a tire diameter. It would also be convenient if I could save configurations.
