Catalyst made a waterproof case for avid Pokemon GO players1
Sealing your iPhone 6/6s/6 Plus/6s Plus from water and dirt while also featuring a transparent panel to let you operate the touch screen, the case also features an extra rubber cap that fits over the phone. Its strips guide your finger when you swipe up to throw a Pokeball at an unsuspecting pokemon. Thus, your aim remains precise, even in moist weather.
The Pokeball aiming accessory comes free with new Catalyst cases, or exists as an optional $9.99 purchase on top of your current Catalyst waterproof case. It's supposed to be sold everywhere in the world.
