Bicycles are so familiar in today’s world that their riders can become almost invisible. You approach a pedestrian or another cyclist, and it feels like you don’t exist: they don’t see you, hear you, or make room. What do you do — shout “Excuse me”? Ring a tiny bell? Sounds a little too polite. Or you can — WoopWoop! Tap one button, and your phone produces a sharp, noticeable, playful, or menacing signal. People turn their heads. Some laugh, some step aside — but most importantly, they notice you. And the best part? That button can live right on your Lock Screen. YOUR SIGNAL, RIGHT ON THE LOCK SCREEN Cyclists often keep their phones mounted on the handlebars. Nobody wants to leave an app open throughout the ride or search for it every time a signal is needed. With WoopWoop, you don’t have to. Wake the Lock Screen, tap the widget — and woop! The signal plays while the app stays hidden. Tap again to stop it. Choose between two Lock Screen widgets: • WoopWoop Minimal gives you one large, easy-to-hit button. It starts and stops the main signal using the preset selected in the app. • WoopWoop Full lets you start and stop the signal, switch presets, and play the quack accent directly from the Lock Screen. Your phone stays on the handlebars, WoopWoop stays out of the way, and your signal is always one tap away. HOW IT WORKS • Tap the big button to start the main signal. It keeps playing until you tap the button again. Stopping the main signal stops all sounds. • While the main signal is playing, a smaller button appears. Tap it to play a sharp quack accent. It stops automatically when the sound ends. Tap it again while it is playing to restart it from the beginning. • Choose from 64 built-in sounds. Assign a different main signal to each of the three presets, plus a separate sound for the quack accent. • The presets are marked with cyclist, scooter, and runner icons, but those are only symbols. Use any preset in any situation and switch whenever you like. WoopWoop is useful, playful, and sometimes a little menacing — the bike horn you never knew you needed. A GIFT THEY DON’T HAVE YET WoopWoop is exactly what’s missing from the gear of those cyclist friends who ride every Saturday in helmets and cycling kits. Bike locks, lights, bottles — they already have all that. But a woop button? Probably not. Buy WoopWoop for yourself, then gift it to a friend. Whoever gets it will open the app, tap the button — and boom: instant delight! CHEAPER THAN A CUP OF COFFEE No subscriptions. No hidden in-app purchases. Everything is simple, just like the good old days: buy it once, and the app is yours — with all future updates included. And here’s a secret: you don’t even need a bicycle to enjoy WoopWoop. Sometimes a button and a little attitude are all it takes to make your day more fun. IMPORTANT: Apple allows interactive Lock Screen widgets to respond only after your iPhone is unlocked. Face ID usually unlocks it automatically without leaving the Lock Screen. If Face ID is unavailable or does not recognize you, unlock your iPhone manually or temporarily turn off the passcode before using the WoopWoop widget. This is an iOS limitation.
