The Armor3 Trigger Kit for Smartphones (model M07363) is a simple, low-cost clip-on accessory that turns a bare touchscreen into something closer to a real controller for competitive mobile shooters. The kit includes one pair of physical trigger paddles that clamp directly onto the upper left and right corners of a phone or tablet's screen, sitting right over the spots where a game's on-screen fire and aim-down-sights buttons usually appear, so a squeeze of the trigger registers as a genuine tap without a finger ever blocking the view of the action. It's built to suit exactly the kind of mobile FPS and battle-royale titles where reaction time matters most, including PUBG Mobile and Fortnite Battle Royale, and works with Android phones, iPhones, and tablets generally, though Hyperkin notes fit can vary with thicker phone cases. At a compact 14.6 x 3.8 x 15.9cm and only 22.68g, the whole kit folds flat and travels easily in a pocket or bag for gaming on the move.
