The “Why”
Every home roaster knows the “Roaster Shuffle”—trying to adjust fan speed and heat power with one hand while frantically checking a stopwatch and doing mental math for DTR % with the other.
I built DTR Log because I wanted a digital workbench that actually understands how we roast. No more messy notebooks or missed milestones.
What’s Under the Hood?
DTR Log isn’t just a timer; it’s a data-driven assistant designed for the roastcoffee.ai community.
- One-Tap Milestone Tracking: Capture Yellowing, 1st Crack, and 2nd Crack instantly.
- Live DTR % Calculation: See your Development Time Ratio update in real-time so you know exactly when to drop.
- Moisture Loss Engine: Enter your green and roasted weights (lbs) to see your exact moisture loss percentage.
- Thermal Benchmarking: Optionally log your temperatures (°F) at every crack to build repeatable roast profiles.
- Pro Data Export: Download your entire history as a CSV file to analyze your curves in Excel or Google Sheets.

I am currently finalizing the iOS version for the Apple App Store. Before the global launch, I am inviting 50 founding testers from our community to get early access via Apple TestFlight.
