The moment you hear the crack, hit the big button once. A dot lands on your curve. Log time, temperature and first/second crack by hand and the roast curve draws itself in real time. Drop the beans and that batch becomes a card in your collection. No account, no server. Your logs live on this phone only. HOW IT WORKS • Charge: the timer starts at 0:00. • During the roast: log the temperature you see on your roaster as often as you like. The screen stays awake while the timer runs. • Crack: when you hear it, tap First Crack (then Second Crack). A dot is pinned to the curve at that second. Wrong tap? Undo it right there. • Drop: the timer stops, total time and DTR are worked out, and a batch card is made. TRY IT BEFORE YOU ROAST A 10-minute roast compressed into 30 seconds. Without a single green bean, tap the cracks yourself and feel the dot land. Demo batches stay out of your stats and overlays. MANUAL ON PURPOSE You write down the temperature you read on the roaster, and you tap the crack when you hear it. The app never picks a roast level for you and never scores your roast. It just keeps what happened, as it happened. DIALS, LOGGED IN THE MOMENT Every time you turn fan or power (1–9), one tap. It draws as a step line in its own lane on the curve and sits in a table on the card, so next time you roast the same bean you can follow "fan 7 at 3:20" exactly. Tap yellowing and end of first crack too, and your drying, Maillard and development ratios line up. Preheat and room temperature go in the batch details. WHAT'S ON A CARD • Time × temperature curve with first and second crack dots • Fan and power changes, yellowing and end-of-first-crack times • Bean, origin, charge weight, drop weight, yield, roaster used, preheat temp, room temp • Roast level (8 steps from Light to Italian, chosen by you) • A one-line roast note Browse your cards by bean or by roast level. No nagging to roast every day. No missions. SIDE BY SIDE WITH YOUR LAST BATCH Overlay the previous curve for the same bean as a ghost and compare as you roast. Tap "Roast again with these settings" on a card and the bean, charge weight, roaster and preheat temp are already filled in. ROASTER'S KIT (optional, one-time purchase) • Replay guide: start a roast with the same bean and the last batch's fan/power changes and crack times sit right beside the timer. • Multi-curve overlay: stack up to 3 earlier batches on one curve. Not a subscription. What's free today stays free. YOUR LOGS ARE YOURS Export every batch to a single file and import it back. Wipe everything at once from Settings. No account · no server · no internet for logging · no photo, mic or location access. No ads, no subscription. One optional lifetime purchase, handled by the App Store.
