Ratio Calc!

I have the app for iphone but I've recently switched to android and would love to use this on my new phone for my rc racing.

App needs to be updated!

Well done! I love the amount of cars you have in the library. Great tool!

Best gear ratio app, hands down!

In a sea of mish-mashed, garbage R/C related apps, this is an aesthetic oasis. It does exactly what you downloaded it for and doesn't give you a migraine in the process. What more do you want? Hmm. Maybe a watch app? Oh yeah, the dude made that too. Excellent work.

Been using this app for years. A must have. They add new cars very quick.

Great app for on the track setups, it's an absolute must for the average to the pro racer!!!

I wouldn't leave home without it. Gone are all my charts, calipers and notes. Good job guys!

Does exactly what you need it to do; quickly figure out gear ratios and rollout. Saves your individual cars and their settings. Buy this app for gearing, you won't be disappointed.
