Could be a 4 or 5 with a few tweaks
When copying to my phones album the map and speed info does not copy with it. Also it needs and option for MPH.
If you really want to get nice record both front and back cameras. Not sure the iPhone will let that work.
Have a paid version so I don’t have advertising at the top. If I’m driving I’m not reading the advertisement.
After all that’s said it actually surprised me how good it works for a free app with only a few reviews. Video worked and the map and speed function is nice. A few adjustments and it will be a 5
