One of the most significant challenges in home coffee roasting is the tension between the process and the record. During an active roast, a roaster’s hands and attention are fully occupied by heat management and sensory observation. Stopping to write a detailed note at the exact moment a “crack” occurs creates a risk: in the few seconds it takes to record the data, you may miss the start of the next phase or lose track of the roast’s overall progress.
As developers of recording tools, we view this not as a roasting problem, but as a management design problem. The goal is to capture high-accuracy data without interrupting the flow of the roast itself.
The “mark and fill” technique
A reliable, tool-agnostic method for handling this is to minimize the “data entry” burden during the active phase. Instead of trying to write complete sentences or log multiple fields while the machine is running, many roasters capture only a minimal mark in the moment.
- The Quick Tick: On a physical notepad, simply make a quick mark or “tick” the moment an event occurs.
- The Split Time: Using a standard phone stopwatch, tap the lap or split button at each key landmark.
Once the roast is finished and the beans are cooling, your attention is free to fill in the full written record. Because you have the precise timestamps saved as ticks or lap times, you can transcribe them into your permanent log while the details of the session are still fresh in your memory.
Streamlining the workflow with Roast Book
At Kore Apps, we designed the Roast Book timer to follow this exact logic of “capturing now, documenting later.” The app provides a dedicated timer-to-record workflow that automates the transcription step.
- Start the Timer: Initiate the timer at the beginning of your roast session.
- Stamp the Landmarks: The interface features dedicated buttons to “stamp” the First Crack and Second Crack times the moment you hear them. If you tap a button prematurely, you can re-tap it to update the timestamp to the most accurate moment.
- Automatic Pre-filling: When the roast ends, stopping the timer proceeds directly to the roast record form. The captured timestamps for the 1st crack, 2nd crack, and total roast time are pre-filled automatically, removing the need for manual transcription.
For roasters who prefer their current manual methods—such as using a dedicated analog stopwatch or a separate physical ledger—the app remains flexible. A fully manual entry route is always available, allowing you to type in your gathered data points after the session is complete without ever using the live timer.

Managing your history
The app’s timer is simply a digital version of the “mark and fill” habit, designed to ensure that accurate data is captured without sacrificing focus.
Roast Book is available to help you build a reliable archive of your roasting sessions.
- Free Tier: Includes the roast timer, tasting radar charts, and management for up to 15 roast records with one photo per roast.
- Pro Tier: Available as a one-time purchase, this tier unlocks unlimited records, up to three photos per roast, and advanced data tools like temperature profiles and detailed statistics.
Summary
Accurate record-keeping does not have to come at the expense of a successful roast. By adopting a “capture now, record later” mindset—whether through a simple tick on a notepad or an automated timer—you can preserve the landmarks of your session with precision. This disciplined approach to timing is what eventually allows you to look back at your data and understand exactly how you achieved your best results.
