If you frequently use you Android smartphone for shooting videos, you will occasionally want to grab stills from it for whatever purpose. While you can probably do that after transferring the clip to a PC, there's now an app you can use to cut still frames right from your handset: Framegrabber.
The process is simple. You launch the app and load a video from the SD card, which it will break up frame by frame in a circular 3D-style arrangement. From there, you can simply scroll through the frames, pick a still you like and save it as an image. You can then send that still as an email attachment or upload it to a social network.
Framegrabber's UI is quite attractive, with very intuitive navigation and straightforward operation. The split-screen design (with the scrolling frames at the bottom and the current frame at the top) very helpful, saving me from having to tap on a frame to see it in detail. There isn't much in the way of settings, though, beyond picking how videos will be indexed (either by frame or by time) and a couple other superficial items.
Do I love Framegrabber's function? Definitely. I'd probably love it more if I was really big into shooting videos on my phone and grabbing stills from it to send out to friends, though -- something I don't think I really have a need for. As it is, the $4.27 price sounds a bit too steep for something I'll probably use very sparingly. Your own needs may vary, though, so it could well be worth the price for you.
