iPhone

Your ears guess. Your iPhone measures. Knock a watermelon and get an instant sweetness read from real acoustic frequency analysis. Knock, listen, choose. Watermelon Maestro uses your iPhone's microphone to analyse the sound of your knock, measuring its pitch and how long it rings, then shows you a sweetness dial and a plain verdict from Skip It to Buy This Melon. Deep and resonant means ripe; high and short usually means unripe. Grounded in published acoustic research, with a five-step illustrated picking guide and seven languages built in. One-time purchase, works offline, no account required.
