Whispr turns your Apple Watch into a live remote mic for your iPhone. Wear your Watch, talk (or whisper, or sing), and Whispr plays it live on your iPhone — through the speaker, AirPods, or connected Bluetooth audio. No recording. No saving. No sharing. Just live sound, wrist to phone. What it's for • A tiny personal PA: park your iPhone nearby or connect a Bluetooth speaker and your wrist becomes the microphone. • A one-way walkie-talkie to your own setup — call the kids to dinner from the garage, hand off the iPhone with AirPods to a friend and chat to them. • A pure novelty Dick-Tracy moment. (Hold up your wrist. Say something. Smile.) Designed to be honest • Live audio only — Whispr never records or saves anything. • Audio stays between your Watch and your paired iPhone — nothing goes online. • Works with the iPhone speaker by default. AirPods and Bluetooth speakers work too — Whispr quietly picks the cleanest playback mode for whichever you're using. A few real-world notes • Whispr uses Apple's Watch ↔ iPhone link. It's great for casual use but it isn't a low-latency studio link. Expect a small delay. • For best live sound, use the iPhone speaker, AirPods, or Bluetooth. • Range is whatever your Watch and iPhone normally manage together. • The Whispr app needs to stay open on your Watch while it's streaming — leave the screen on (raise to wake) so the session keeps running. • If your iPhone is locked when you tap the Watch mic, your iPhone will ring just like an incoming call — accept to start listening. Not a hearing aid, not an amplifier, not a recorder. Whispr is a small playful utility — it doesn't boost faint sounds for you, it just plays whatever your Watch hears live on your iPhone, full stop.
