I use this during airplane takeoffs&landings. It's fun to know your speed and I wanted an app that would speak them to me so I can look out the window and not at the screen. It works perfectly! All the other ones i've tried lag too much. My one complaint is regarding an apparent bug: if the "voice interval" is on speed mode when launching the app, the audio does not work. If I switch it to time mode and then back to speed mode, it seems to work. Also, it would be nice if on time mode there were an option for speeds to be read up to 2 seconds (currently the highest frequency is 10 seconds).
