Slap the air. Your watch cracks back. Slappy Hands turns a flick of your wrist into a sound you can feel. Motion in, sound out — no menus, no setup, no waiting. That tight little loop is the whole point, and it's the reason people keep doing it long after the joke has landed. Then it escalates. The first slaps sound real. Keep going and they drift into cartoon, then absurd, then full explosions — a designed arc, not random noise — with rotating one-liners along the way. Tap the flame to skip straight to chaos. Built for feel: • Instant response — motion detection tuned by ear, not by spec sheet • Four sound tiers that escalate as you go, then reset so the arc can run again • No sound repeats back-to-back, so it stays alive the hundredth time • Keeps sounding even when the screen dims mid-session • Visual feedback timed to every hit: pulsing ring, color shift, flash • Rage-shake detection for when you really commit • Works on either wrist, arms itself when you raise it, sleeps when you don't • Launches straight from a watch face complication • Tap to see your slap count for the session No account. No ads. No tracking. Nothing leaves your watch. Just slap.

From your own phone, your Apple Watch, or your PeekSmith, you secretly control the clock on your spectator's phone. They're holding what looks like an ordinary clock: stopwatch, timers, alarms, world clock. Every one of them is yours. ALTER TIME ITSELF A spectator starts a stopwatch on their own phone, in their own hands, and stops it whenever they like. It stops on your number. No sleights, no switches! The phone does the magic for you. BORROW ANY IPHONE, NO INSTALL Nothing to download, no account, no setup on their end. A tap, a QR code, or a link puts your clock on their phone in seconds, and it disappears on its own afterward. Borrowed-phone magic that actually feels organic. FORCE ANY TIME OR NUMBER Five force modes built for real routines: • Manual: land on the exact value you choose • Addition Total: the digits sum to your prediction • Full Time: force a complete minutes-seconds-hundredths reading • Multiple of 9: self-working number math • Lap Times: force the totals across multiple laps And not just the stopwatch: force which city appears in their world clock, the time an alarm is set for, and where a timer lands. REVEAL IT IN THEIR HANDS Turn a quiet force into a visible moment of impossibility. On your secret cue, or when the spectator shakes their phone, waves a hand over it, or touches the screen, the clock they're holding visibly animates to your forced value. Add a delay to time your line, plus a synced 3-2-1 countdown you feel buzz in your hand as it lands, so you can choreograph your magic wave to reveal the time, location, and more. Afterward, everything stays examinable. PEEK EVERYTHING THEY DO, LIVE Your phone quietly mirrors the spectator's screen in real time: every start, stop, lap, alarm, timer, and city they pick. Perfect ammunition for predictions, revelations, and readings, before they even know a trick has started. CONTROL IT ALL FROM YOUR WRIST Run the entire effect from your Apple Watch: arm forces, fire reveals, and peek live values with your phone still in your pocket — or let the watch run the show entirely on its own. MORE THAN A STOPWATCH • Practice Mode — rehearse the full routine offline, anywhere • Rock-solid connectivity: direct device-to-device link with automatic cloud fallback • PeekSmith display support for stage-ready peeks • Your settings and force lists follow you to any device ClockWork is built for working performers. The clock in their hands is yours. This app is for entertainment purposes only.
