For Android, the preferred way to transfer video results is using an external SD card and simply copy the overlaid video from the Movies folder. The exact position on the card can be seen in the Video's Details View from either Lap Details or Video List. For devices with an "internal SD card", things are a little more tricky. Usually this devices come with some desktop explorer to access the "card" while the smartphone is connected using USB. I had some trouble with my Nexus4 which didn't expose the Movie folder used by LapTimer in the corresponding tool. In cases like this, you may consider using an Android file manager like OI File Manager.
