GetBolla is the sensor for home kombucha brewers who are tired of opening the jar every day hoping to guess the right moment. The sensor sits directly in the jar alongside the SCOBY. It measures pH and temperature every 5 minutes and sends the data to the app. When your kombucha reaches the ideal bottling point, you get a push notification. No more blind tasting. No more wasted batches. — WHAT THE APP DOES — · Real-time fermentation status: Fresh / Active / Almost Ready / Ready / Too Sour · pH and temperature charts hour by hour, annotated by phase · Acidity trend: falling, stable, or rising · Estimated time to the ideal bottling moment · Push notifications for: ready to bottle, too sour, temperature out of range, sensor offline · Second fermentation guide with flavor selection and per-bottle notes · Full batch history: pH drop, fermentation rate, thermal stability · Home screen widget: pH, temperature, and trend always visible · Educational cards on the science of fermentation · Contextual tips for every stage of the batch · No subscription. App is free. The sensor is a one-time purchase. — HOW IT WORKS — The GetBolla sensor connects to your home WiFi with no additional hub. Once set up with the app, it works on its own: measures, records, notifies. It has a built-in display showing the current fermentation stage, readable directly from outside the jar. Powered via USB-C from any standard charger. — WHO IT'S FOR — Home brewers who have been making kombucha for a while and want to stop wasting batches. Beginners who want to start without fear of failure. Experienced brewers who already use a pH meter but want continuous automated monitoring instead of manual snapshots. GetBolla. Your kombucha ready at exactly the right moment.
