The short answer:
If you have an iPhone 6, 6S, 6+ and 6S+, then most definitely! Just purchase a lens kit at Shop.
If you have an iPhone 7, yes! But for now, you'll have to make your own case.
If you have an iPhone 7 Plus, yes for using it over the 1X camera! But for now, you'll have to make your own case. Note that your other camera is a 2X camera with slightly lower performance than the 1X camera (f 2.8 vs f1.8, no optical image stablization). Our telephoto camera is 2.5X, and goes over a better camera, so provides slight different capabilities than your 2X camera.
Here is a list of popular Android phones it is compatible with:
Note that you'll have to 3D print / make your own case to fit these phones! Watch for more news on this topic soon.
The long, techie answer:
Generally speaking - our lenses are designed and made in such a way that it can optically work with any phone. We used the iPhone 6S camera as a reference, so the closer the specifications of your camera to that phone camera, the better the fit (75 degree field-of-view, f/# 2.2, 12MP resolution).
So, if there is a:
1. field-of-view mismatch - there can be some dark corners.
2. F-number mismatch - the image can be brighter or darker in general. Our lenses are actually designed to f1.75.
3. Resolution mismatch - some blurring can be introduced.
All lenses are designed this way! They might not admit it, but it's true :)
