The iPhone can do a lot but there is no app for making it waterproof. For that you need a case, and while there are plenty of big and bulky housings available, the Keystone ECO MarineCase is another good option as it is slim and compact but will still ensure that the smartphone can survive underwater up to 20 feet or six meters.
The clear protective silicon cover allows for use of the iPhone screen and won’t interfere with call functionality. Users can still playback video, send email, use apps and more whilst sill in the water. The IP58 certified case will protect the handset from snow, rain, dust and sand, and even let users snap non-flash photos and take video underwater.
