Wow, it does so much more, and displays in landscape or portrait. Can change display colors, review flight later with speed, times and altitudes, and the instructions are fantastic, great product, worth a lot more than I paid for it!! ***** Malix90x – Jun 7, 2016 It is the best in its genre as it is the most complete! So many thanks to the developer :) ***** TxHornyToad – Jan 3, 2016 In a large field of "Speed" apps this has to be the best. Very clean and clear display. Very customizable. Responsive support. ***** R8Jimmy - v4.5 - Jul 6, 2013 Works as advertised. Very informative when using it on my motorcycle. Display is easy to read. Excellent support from developer.

Perfect and thank you!!! ***** Brimstin85 - v4.1 - 22-Nov-2012 The information is large, easy to read, accurate, and intuitively laid out. The app is easy to use and very capable. It has plenty of advanced features too. Worth every penny. ***** v2.7 - 19-Aug-2011 The display is very clear and easy to read in a car and on a bike.
