Description
Whistle turns your phone into the loudest thing in the room.
Six distinct whistle sounds, synthesized in real time—not recordings, not samples. Every blast is generated fresh, with authentic trill, breath noise, and harmonic texture that actually sounds like a whistle.
THE WHISTLES • The Screamer—a piercing referee blast that cuts through any crowd • The Guard—sharp lifeguard authority, built for attention • The Coach—classic metal pea whistle with commanding presence • Old Timer—warm, rich tone with deep harmonic character • Foghorn—a low, resonant bellow for dramatic effect • Dog Whistle—ultrasonic
FULL PATTERN CONTROL Single, double, triple, or rapid-fire—choose your blast pattern and set the gap between bursts. Enable Repeat Cycle and Whistle loops your pattern automatically until you tap stop.
YOUR SOUND, YOUR WAY Dial in duration from a quick 0.1-second chirp to a 2-second sustained blast. Adjust volume. Set the pause between repeat cycles. Every setting is live—change it mid-play and hear it instantly.
Works in silent mode. Plays in the background. No ads. No account. No internet required.
