Swing your phone and the hum follows. Any blade colour, sparks on impact.
Hold your phone upright, tap once, and the blade extends. Swing your arm and the sound follows your hand. Move slowly and it hums low. Cut fast and the pitch rises while a rush of air mixes in. This is not an app that plays a stored laser sword sound. It turns how fast you actually swing into sound, right there. Your swing speed makes the sound The gyroscope reading is mapped straight onto pitch and volume. Nothing is picked at random from a handful of clips, so a gentle wave hums gently and a hard cut tears. Repeat the same move and it comes out slightly different every time. The app generates the audio itself There is not a single recorded file inside. Two close frequencies interfere with each other, and the app synthesises that beating in real time. That is why the pitch can slide freely, and why the flicker on screen moves on exactly the same rhythm as the sound. Any blade colour you like Seven presets, plus a colour bar you can drag to mix your own. Whatever you pick is remembered, and the home screen, the records screen and the shared image all change to that colour. Three sound styles Smooth, Deep or Rough. Switch right on the blade screen, even mid-swing, and the sound carries on without a click. The blade colour changes on the same screen too, with no ad in between. Sparks when you hit something When the accelerometer catches a sudden impact, sparks scatter across the screen and a short, heavy buzz comes with them. Try tapping something soft, like a cushion, gently. Walking around or carrying the phone in a pocket will not trigger it, because impacts only count while you are actually swinging. Your swings are counted Total swings, best swing power, clashes and time switched on all add up. From the records screen you can turn them into an image and send it to a friend. Who this is for Anyone who wants a prop to play with in a dark room, or a glowing prop for a photo or a video. Please note This app produces light, sound and vibration only. It is an original prop simulator, not a real weapon, and it has no connection to any film, series or brand. The colours and the handle shape are our own designs. No ads appear at all while you are swinging the blade. A full-screen ad may appear when you tap Start on the home screen, and there is a banner at the bottom of the home and records screens.
