Fills a niche...
This isn't the most polished app in the world. Resizing and zooming can make it thow-up. But dial it in and resize it how you want it and it's stable enough. That you can crop on the fly makes it just what you'd want for a rear-view mirror.
$1.99 is, well, high for something of this finish in a land of 99cent accesory apps. But, really, it's better than the other choices I've seen. The best thing it has going for it is that it can handle usb cameras and isn't just restricted to iSight.
Suggestions? A frameless window. Make all the on screen options go away when in use. Make it more like a dashboard widget.
Terrible horrible no good very bad
With Family Sharing set up, up to six family members can use this app.
