Explain bugs to a duck

Quack is a rubber duck debugger that lives in your pocket. The age-old trick works: explain your bug out loud, step by step, and the answer often appears before you finish talking. Quack gives you a friendly duck that listens — by text or hands-free voice — with zero judgment, no internet, and no account. WHY QUACK • Talk it out: type or speak your problem and walk through it line by line. • Voice mode: explain bugs hands-free while you keep your hands on the keyboard. • Private by design: your words are processed on your device — nothing is stored or sent to a server. • No account, no sign-up: open the app and start debugging in seconds. • Works offline: think on a plane, on the train, anywhere. HOW IT HELPS Rubber-duck debugging is a proven technique used by developers everywhere. Articulating a problem forces you to slow down, check your assumptions, and spot the flawed step. Quack makes that ritual delightful and always available. Free to use, with an optional one-time purchase to remove ads.
