The main function of the covers - defensive - today is practically "killed" by manufacturers, having produced the "Sponge of Beans", "Hello Kitty", "Avengers", which exclusively decorate the smartphone, without protecting it in any way. The second side of this “medal” is to try to add to the case the functions that it should not have, making it a wallet, turn-bank, manicure set, pepper spray, action camera, VR glasses, ECG device or whatever you like: modular . About such covers - today.
Ps. Inside there is a gif.

While Yota is
convincing in the 35,000th draw of its two-way smartphones, and Kickstarter is collected on the next
two-screen smartphone , Oaxis continues to make covers for the Iphone 5 -
InkCase - one of the sides of which is an additional e-Ink display. The case is paired with the application, and through it "draws" the photo galleries and e-books.

')
Nexpaq - modular case that works on the principle of "Lego". The user is given the opportunity to choose what his case will be endowed with: flash, flashlight, camera or additional acoustics. True, to control the modules have to use a special application. The cost of the
official store from $ 15 per module or $ 65 per set.

Covers-wallets - a common and understandable design, but the cover exclusively for cards -
Gresso . The model is designed for Iphone 6 / 6s and is made of durable aluminum.

True, in fairness, I must add that Gresso, of course, is not the only one.
PushCase works
equally well , which by clicking on the button opens access to credit cards.

Despite the extremely developed “ecosystem” of the
Power Bank , covers with a built-in battery are also relatively common. An unusually wide range of models of different capacities can be found in the store
Mugen Power .

On the other hand, we recently
wrote to Geektimes about the Power Bank model, which “swiftly” charges the smartphone without harming the battery, so that the cover can be chosen based on other principles.
Cases for photographers "grown" out of the niche overhead lenses. And one of them is worth mentioning -
VicamPlus . A waterproof case that “turns” the Iphone into a GoPro action camera. According to the authors of the project, it is ideal for sports, recreation and tourism, and all the necessary fixings are included.

Waterproof cover "simpler" was created for those who are not ready to part with a smartphone under any circumstances,
even during a shower . Attached to the wall so that you can keep track of incoming calls and likes in social networks.

A similar conceptual cover for those who are not used to living without a gadget, only for fastening in "waterless" places is called -
Wallee M.
The failed company on Kickstarter -
Cordli - offered a completely understandable and maybe even the necessary case that solved the problem with tangled wires.

However, the authors of the
Skybuds project went even further, presenting their case for a smartphone, which is sold along with wireless headphones, for which, in turn, there is also a place in the same case. Apparently, they are waiting for success.

A cover for travelers and anyone who prefers an active lifestyle is on the shoulder, and then the leading company is
Armpocket . Breathing recycled material, snug fit to the shoulder, extra strong and roomy enough to load, say, keys or cards and money. Protection against dust and moisture + headphone outputs and the ability to control the phone.

File, scissors, screwdriver, toothpick. In general,
in1case offers a strange set for the cover, however, judging by the price tag of $ 30, it should be quite reliable.

An interesting case for entertainment offered by the company
vrAse . The analogue of a
virtual reality helmet differs from the latter in that the image is served separately for each eye, due to which a 3D effect is created. So the main "consumption" - watching movies. Also, the frame is collapsible, and one of the parts can be used as a bumper for a smartphone.

A security case, unfortunately, never
received recognition , would allow sprayers to spray pepper spray, and in a proven company it provided the girls with a supply of perfume.

And in the final one more interesting project, on our subject - medical, AliveCor, when together with the case you get a portable ECG device. The device is paired with the application, and the cost of the
kit is $ 85 .
