SMD is a watchOS app that turns Apple Watch into a magnetic detector and provides haptic alerts for nearby magnetic field changes. You can switch between the analog clock screen and the Settings screen with a swipe. SMD offers two operating modes: Manual Mode and Motion Mode. In Manual Mode, detection starts and stops with a tap. In Motion Mode, raising the wrist starts the sensor, and briefly holding still completes the set process and makes the app ready to use. Lowering the wrist stops sensing. Motion Mode also supports tap-based OFF and re-set actions. Detection and alerts become active only after baseline acquisition is complete. Sensitivity can be adjusted from the Settings screen using the Digital Crown. The Settings screen shows ON / OFF status, X / Y / Z values, mode switching, sensitivity, and version information. When magnetic reference is inactive, X / Y / Z values are shown as -.--. Key Features - Magnetic detector functionality using Apple Watch - Haptic alerts - Manual Mode and Motion Mode - Sensitivity adjustment with the Digital Crown - X / Y / Z value display - Automatic polarity detection - Stable single-trigger alert behavior Important Notes - Do not use magnetic watch bands - Strong magnets may temporarily affect sensor readings - Apple Watch Series 10 or later is recommended

Cue Killer is show control for performers who run their own AV. Build one ordered cue list, press GO, and let the next slide, sound, video, camera cut, overlay, blackout, QR moment, or transition land exactly on your beat. Made for magicians, mentalists, speakers, musicians, comedians, event hosts, worship teams, buskers, and anyone who has to perform and run the booth at the same time. WHAT YOU CAN CUE - Slides, PDFs, Keynote/PowerPoint exports, images, video, audio, live camera, text, frames, lower thirds, QR codes, audience polls, waits, groups, mic/listen mode, blackout, and stop-audio cues. - Audio cues include fades, crossfades, looping, trim, level control, and a dedicated kill-audio action. - Visual cues can use cinematic crossfades or dip-to-black transitions, plus branded overlays and big live text. RUN IT HANDS-FREE - Map GO, BACK, LIVE, blackout, deck navigation, and audio actions to Flic buttons, Bluetooth clickers, game controllers, MIDI, OSC, or the built-in web remote. - Add spoken trigger phrases so a line in your script can fire any cue. - Use the camera to recognize a prop and fire the matching cue while your hands stay in the routine. BUILT FOR THE BIG SCREEN - Send clean audience output over HDMI or AirPlay while your iPhone or iPad stays on the operator console. - Use live camera cues with zoom, picture-in-picture/split layouts, peer cameras, browser cameras, and overlays. - Fire audience interaction cues: the crowd scans a QR code or enters a short code at cue-killer.com, then votes in live polls, number guesses, or word clouds. BUILD FASTER - Import media once and reuse it across shows. - Import Go Button, StageCue, and CSV show files. - Use Killian, the in-app assistant, for setup help and for generating show ideas, cue drafts, images, sound effects, music beds, and voiceovers when you connect your own AI keys. CONFIDENCE UNDER PRESSURE Cue Killer is designed around the live moment: what is on air, what is standing by, what GO will fire next, and how to panic-silence everything fast. It is approachable enough for a solo performer, but serious enough for a real stage.
