Gear Speed Calculator

THOSE WHO CANT FIND THE MENU BUTTON. This app hasn't been updated for phones without the 4th button at the bottom of the screen. That's the one needed to open the settings tab and configure the max RPMs you want it to show along with change RPM increments. If you have one of those phones it works great. If you don't have an old phone, you're just like me stuck with the default 10,000rpm with 500rpm increments

Good but....it needs the option to add more gears than just 6. Too many new cars are capable of 8 to 10 gears and would be useful.

Doesmt work, fill all the gear ratios, doesnt give amy answer or has a buttom to get results! Not even 2 min in app & already deleting it!

doesn't have my tyres sizes. plus an option for Imperial would be nice. not suitable also for motorcycle. app needs update.

Love this app. Constantly use it for bench racing, figuring out new trans and rear end combinations

Developer of this app passed away a decsde ago so he can't help you with the menu butoon.

absolutely love the app!! Can't locate the setting tab. I have looked for it on my galaxy on5 and my galaxy E tablet???

Doesn't have race tire sizes, only street tire sizes.

I use to have the 4th button (menu button) where the heck did it go? Can we kindly have a freaking fix?

For cars only

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.

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

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 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.

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

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

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.

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

this app makes it so easy to get nissan gear ratios...GTR tune here i come.

There's one problem and that's my phone doesn't have a menu button

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

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

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

Solid replacement for Mfactory's old website calculator/graph.

On Samsung Tab S2 & S7 could not fin menu button to change settings.

Good app needs more presets

The best Automotive App ever

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

Cheers mate.. works great!
