Hey Product Hunt 👋 I can whistle. I just can't whistle *in tune* — and I never had any way of knowing which part I was getting wrong. Singing has a hundred pitch trainers. Whistling has none. So I built How to Whistle. You pick a tune, it plays, and you whistle along. A white line tracks your pitch against the melody as you go, so you can hear and see the drift in the same moment. When the song ends you get a breakdown: pitch accuracy, timing, and which notes you missed entirely. What's in there right now: • 21 songs, difficulty 1–5 — folk and classical, all public domain • Transpose any tune into your comfortable range (there's a range test to find it) • Half-tempo mode for the hard bits • A daily challenge with a global leaderboard • Works on desktop and mobile Two things I care about: • It's free. No account, no signup, no paywall. • The microphone audio is processed in your browser and never leaves your device. Nothing is recorded, nothing is uploaded. Whistling is one of those skills nobody teaches — you either picked it up as a kid or you didn't. I'd love to know: did you learn it, or is it still a mystery to you? And what tune should I add next?
