User Reviews and Ratings

★★★★★ Best roll-out calc out there

Keep it up !!!!!! Your last updated totally made my day.

★★★★★ Fantastic!!

Great place to keep notes and gearing for all your cars. Enough models for every occasion!!! Store multiple cars and compare final drive ratios or roll out for accurate records. Will definitely save money on spent motors and speed controls due to over gearing.

★★★★★ Please create this for android

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.

★★★★★ Simple, clean, perfect!

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.
