The paid version records the last 5 minutes of your trip.You can check the recorded screenshots any time while the app is in the foreground. Useful if you miss a roadsign and can not go back. The screenshots have the speed stamped on them. Useful if you have to prove your speed to the police. Recording needs about 900 megabytes on SDcard.
In the settings you can set the red spot's width to be found.
A bigger width means that the alert sound comes only if the spotsize reaches or exceeds the preset width.
The spotwidth can be adjusted also by touching the screen of the camera view.
If "use GPS" is checked then the alert sound comes only if the speed is bigger than the limit set at the "speed limit" field and if the red spot is in the view and the red spot's width is at least as big as the preset value.
If "use GPS" is un-checked then the alert sound comes always if the red spot is in the view
and the red spot's width is at least as big as the preset value.
