Whistle Blow
The best whistle app!
₹ 99
Blow Whistle turns your iPhone into a crisp, realistic whistle, with no extra hardware required. Trigger it your way: blow into the microphone, shake your device, tap the screen, or activate it remotely from your Apple Watch. Perfect for getting attention, coaching, pranks, or quick sound effects.
Adjust exactly how you want it to respond with microphone sensitivity controls and full volume adjustment. Choose your preferred whistle sound and, if you wish, display a live microphone level meter for visual feedback.
Features:
- Blow-to-whistle with adjustable microphone sensitivity
- Tap or shake to trigger—no microphone needed
- Apple Watch support: trigger from your wrist
- Select from multiple whistle sounds
- Volume control for any setting
- Optional on-screen microphone level meter
- Works offline, lightweight, and fast
Privacy-Friendly:
- Microphone access is only required for the blow-to-whistle function. You can still tap, shake, or use Apple Watch without microphone permission.
Note:
Blow Whistle is intended for fun and everyday use. It is not a replacement for safety equipment or emergency signalling.
Compatibility:
- iPhone and iPad
- Apple Watch (requires paired iPhone)
