Gear Speed - Brushless RC Speed Calculator

Useful but lately sometimes my days saves sometimes it resets and I have to input the data again!

Every time I click on app it open to a blank screen with an + sign and I click it ,it goes back to my phone screen

The app comes up Then I choose the + And the app disappears Just like my dollar

Doesn’t work on IOS 17!!!!!

Doesn’t do anything. Can’t believe I wasted a whole dollar on this.

It’s just the best app you can possibly get to do your gearing for rc cars and you won’t find a more accurate app out there anywhere i’ve looked it’s worth the money

It used to give me pretty accurate info. Now, with that same info it predicts my RC will go 3467MPH? Created new sheet and still show same. Please correct if your going to charge for this app.

Cool app definitely helps alot

This app should have different gear pitch types

Good tool but lacking some basic things that would take it from good to great. There’s no way to reorganize your list, which would be really nice to group models together with different gear and tire setups. I’d really love to see a master car list with a sub-list of available gear, tire, and battery options. As a quick and dirty tool, this gets it done.
