Tonebg, United States ***** Law Enforcement Applications "Most recently I have taken a law enforcement radar class at which point we are required to calculate a persons speed over a specified distance and this application is perfect! Big props to the "developer. Aub'r Dean!, United States ***** Brilliant! "With the inclusion of the in app timer it's even better. A must have app!!" - Yorky Mike, UK ***** Thanks "Great app I'm using this for long journeys with the car and time trials for my bike. does what it says on the box :)" - ipodalong, UK ***** Does what I need, and does it well "I use this for flight, and flight simulation purposes among other things. Having units such as Mach, knots and nautical miles means that it is perfect for what I need and it can be used for many things. Thanks to the developer, great having this on an iPhone" - Donald Webb, UK
Good app, simple and easy to use. That said, something that would be very helpful to auto racing fans would be the ability to time consecutive laps as well as see the average speed of each lap. In other words once you start timing, the ability to stop the lap timer at the end of each lap so you can see that lap’s time and average speed but in the background the timer continues to run collecting both the total time and the next lap’s time.
Very neat and helpful app!
Use it for duty with uscg all the time!
Easy to use. Very useful at races!
Great app for calculating speed and distance, a tad confusing when it come to the plugging the numbers in though.
Im a Trucker and use this app on the daily!
This app is a great planning tool for those who aren’t great with numbers but are planning a long trip
This app helped me understand just how much time I’m saving (a real eye opener). For example, this app showed me that I only save 2 minutes and 5 seconds if I speed up 5 mph over 27 miles on the interstate. It’s not worth the stress and lost mpg to ram & jamb for 2 minutes. Thanks for making this tool.
Great Ap as a Tugboat Captain this is a great way to get your ETA down to the min as a backup to electronics, here in Hawaii there's a lot of Tugs with ETA's of the same so this helps a lot!!!
Easy to use and great way for this mathematically challenged sailor to figure out speed, ETA, etc.
