Best gear ratio app, hands down!

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.
