Buttekha

Never pick a bad watermelon again. Buttekha uses your phone's camera and microphone to evaluate watermelon ripeness in seconds. Take a photo, give the fruit a firm tap with your knuckle, and get an instant verdict with a confidence score. HOW IT WORKS - Take a clear photo of the whole watermelon - Hold your phone against the fruit and tap it firmly with your knuckle - Buttekha analyzes the color, the field spot (the yellow patch where the fruit rested), and the acoustic resonance of the tap - You get a Ripe or Not Ripe verdict with a confidence percentage THE SCIENCE A ripe watermelon has a deeper, more hollow-sounding tap than an unripe one — that's why grocers thump them. Buttekha listens to the same acoustic cues and combines them with visual signals from the photo to make a calibrated prediction. Both signals contribute to the verdict; when they disagree, confidence is shown lower. PRIVACY-FIRST DESIGN - No accounts. No personal data. - Predictions run on your device — instant, offline-capable - Anonymous session data helps us improve the model over time - Available in English and Arabic Whether you're shopping at the supermarket or picking from your own garden, Buttekha gives you confidence in your choice.
