Sound familiar?

“Once again, RoasTime isn't syncing”

RoastSource is local-first — your log lives on your device and works offline. Sync is additive, never required.

“I want my roast data out — CSV, anything”

Export is a feature, not a request thread. Your history is yours to take.

“RoasTime has the curve — but where do my greens and cuppings live?”

RoastSource holds the rest: which green you used and how much is left, how the cup scored, and what to change next batch.

One app, from green bean to brewed cup

Inventory, roasting, ratings, blends, brewing, and coffee education — offline, private, and yours.
