Few things are as satisfying as when slides during a presentation perfectly match up to the beat, which is where this app specifically designed for slideshow music comes in. Based in Germany, startup Beatsnap! is focusing on a very specific niche when it comes to presentation tools, but an interesting offer all the same.
Beetsnap! synchronizes your photos to music without any tweaking. To use, you simply pick a track and shake your mobile device until the video is pleasing to you. Of course, there is also a social share option, so your friends can take a look as well.
The slideshow music app is great for music festivals, DJs and other concerts who want to add a multimedia element.
