SloPro - Slowmotion videos with your iPhone

I am constantly looking for gem's on the App Store that really stand out from the crowd. In this case i found a cool app called "SloPro", and it does what no other app i know can: With this free app (more functions come with IAP: 2,99€) you can finally take slowmotion videos with your iPhone.
Don't ask me how the developers did this, but it works. And boy does it look good for a simple app.

Features:

- Toggle slow motion while recording!
- Trim and change slow motion afterwards if needed
- No rendering delay--watch slow motion immediately!
- Facebook upload
- YouTube upload
- Upgrade to email, export to camera roll, and export raw 60fps
- Import videos
- Super slow motion - 1000 FPS!
- Fast motion
- Optical flow
- Ghosting
- Frame blending
- Exposure/white balance lock

Unfortunately, 60fps is only for iPhone 4S (and of course the new iPhone which is probably going to be announced today), this is due to hardware limitations.
I tried the app out and its much better than i expected. The interface is held very simple, you release the shutter and the iPhone starts filming, if you want to toggle slowmotion you can do that anytime with a small button on your screen. You can switch it on and off whenever you like. After you have taken your video, you can edit it within the app, adding and deleting slowmotion at any point of your video.

What i really like about this app is that it doesnt produce a fake effect. You won't get a choppy result because the app just takes 30fps or uses another trick to do this. With your iPhone 4S and SloPro you will get wonderful 60fps, and if you wish you can even get up to 1000FPS slow motion, but of course it will never look that good. Still it is interesting to experiment with.

My thoughts on SloPro:
Since its free, download it and experiment with it. Your own opinion is always the best one for yourself. I really like this app, but since i am probably not going to use it that often (there arent that many moments in my life where i really need slowmotion videos, and furthermore i prefer taking pictures over videos), i will probably not buy the full package.
Still, there is no reason i would stop you from buying it, since i havent found absolutely any flaw in this app.
