Log every hand-roast so you can repeat the good ones
Record beans, heat, timing, first and second crack, and weight loss for each roast, so you can reproduce a great batch from numbers instead of memory.
US$5, bought once. Payment is handled by Gumroad. JPY pricing is planned for the future Google Play editions.
From buying it to using it offline
- Buy on Gumroad and your license key arrives in the receipt email.
- Swap that key for an unlock code at ektopos.app/redeem, then paste the code into the app.
- You need the internet only the first time (about 10–12 MB). After that it runs with no signal.
What it does
- Record origin, green weight, heat, phase times, first/second crack, and drop
- Get the weight-loss ratio from before-and-after weights
- Line up past logs to find what made the good cups good
What it does not do
- Works offline · no account · one-time purchase · no tracking · no ads
- Does not control a roaster or read a thermocouple — a manual logbook for recording and review
- It will not tell you the right roast; your palate sets the target, the tool only holds reproducibility
