Ratings and Reviews
Great app for engines
Disappointed. There should be a means by which to enter a final gear ratio other than 1:1. Every vehicle on the road today has an overdrive transmission. It would certainly help if this app would permit the entry of the overdrive gear ratios to accurately calculate engine rpm, rpm at vehicle speed, etc.
I opened this app one time when I bought it. The next time i opened the app I could no longer switch between different calculators in this app now I can't use this app at all.
With Family Sharing set up, up to six family members can use this app.
