Ratings and reviews

The app has received a few recent updates & continues to be supported. The email support is great, the developer is receptive to feedback and suggestions. Should you require a Distance, Time, and Speed calculator, this app will meet your needs. The one-time purchase is also quite reasonable.

It's nice to know the 125 mile ride I'm taking doesn't make any sense to go any faster than 60 mph. To risk going 65 and getting a ticket isn't worth it, but going 60 in the 55 won't get me anymore than a warning, and save me aprox. 11 minutes. The time saved going 65 isn't worth a ticket for the little more time saved. Nice app!

Does what it says. Simple and light. No fuss. No muss. Enter values and get results. Easy. Thank you. After thought: I use this for large numbers and am happy it accepts those values. That said, could you allow for Mach and light year?
