The reason I ask what you will be using it for is to determine which set of features you need. If you're going to be using it for simpler activities, don't go all out for a Black edition with a 60fps, 1080p cam (all HERO3's are 1080p, anyways). The reason the Black Edition is so expensive is because of the crazy quality it has, and if you're using it for a more simple basis I wouldn't worry about the difference. The Silver or even White is perfectly fine for you. The main difference between these two is the white's camera has a 5 megapixels with 3fps burst while the silver is 11 megapixels with a 10 fps burst -- is that worth $100 to you?
What GoPros are compatible with the app?
All GoPro cameras cover the basics of action cameras: they’re portable, waterproof, and rugged enough to tag along on any outdoor adventure, and they also take high-quality video. Beyond that, however, there are some big differences across the product line, including some features that are worth paying extra for. Here are the GoPro camera capabilities to consider keeping on your short list.
A. Not without some extra gear. All GoPros have a waterproof rating that’s expressed as a depth; for example, most of them are rated as waterproof to ten meters, meaning you could swim about 30 feet down with your GoPro camera and it would still work. However, some users want to push those limits even farther, and for them, GoPro makes the “Super Suit,” a reinforced plastic housing designed to withstand water depths to 60 meters. If you’re shopping for equipment for deep-sea photography, plan on getting a Super Suit for your GoPro.
What is a good GoPro?
I have been getting a lot of questions about which type of GoPro camera one should buy if interested. I first think it is great that you're looking into finally getting one, especially after watching the latest events on TV and all of the great camera angles they were able to capture of the professionals. I've had mine for 2 years and could not be any happier. Just last weekend I attached it to my dog on our hike and posted it to Facebook and got some likes from a few cute girls (because likes mean everything, right!?). I'll post the video later this week. I digress, and provide you with some tips when deciding to purchase your GoPro. We also highlighted the difference between the GoPro Hero 4 and 3+ cameras, so be sure to read that for some more help!
