[Coffee x IT] An app is born to challenge the 'reproducibility' of pan roasting!!
Hello everyone. This is "Note I really love cats". Finally, my friend, the AI Gemini, and I have joined forces to create something incredible.
Its name is the pan roasting support app, "Pan Roasting Assistant (Tentative)"!
Please feel free to try out this app!

About the taste of recently roasted beans
About a week ago, I roasted some "Guatemala Las Nubes Farm Red Bourbon" myself. It has a very clean, washed-like flavor and is delicious, but I have the luxurious problem of it being a bit too well-behaved, making it difficult to bring out its unique character.
On the other hand, the "Brazil Chocolat Esperanza" I roasted earlier had a surprisingly chocolatey feel! A sweet aroma wafts even from the grounds after extraction; it's expensive, but definitely a repeat buy!
Graduating from being an "intuitive roaster" after two years?
Actually, it's been over two years since I started roasting, but I've always roasted by "intuition". My style is to vaguely follow a set temperature profile once on the weekend. I've never even recorded the actual measured values once (lol).
That's when I started to get interested in the concept of "ROR (Rate of Rise)". It's an indicator of how much the temperature rises per minute. They say that if you nail this, coffee becomes even more delicious.
Gemini, my "best assistant"
That said, taking notes with one hand while roasting is a daunting task. If I had a cat, I'd want to ask it to "record it for me!", but unfortunately, I don't have a cat at home.
So, I consulted my AI friend, Gemini. I asked, "Could you help me make an easy-to-use app that supports pan roasting?" And that's how "Pan Roasting Assistant (Tentative)" took shape! *Currently, I am struggling with the screen design and iOS notification sounds. This is still being investigated as an "unsolved case"...
🌟 It is packed with features like these
Visualize the gap from the ideal: You can compare the pre-determined target temperature with the current temperature in real-time.
Easy to see with large text: Since it's hot and busy during roasting, I made the elapsed time display nice and big.
Alert every minute: A sound plays at the 55-second mark to tell you, "It's time to measure the temperature!"
Record cracks with one tap: You can record the timing of the first and second cracks and look back at them on a graph later.
Data export: After finishing, a cool PNG graph and CSV data are saved.
Looking ahead
"Registering data with good results into the next profile to improve reproducibility"—doesn't that sound professional and a bit exciting? Until now, I've been nervous, wondering, "Did I roast it well today?" but from now on, I can have a strategy meeting with Gemini, looking at the accumulated data and saying, "Let's try this next time."
I hope this app becomes a catalyst for families and friends to start hand-pan roasting together.
Thank you for reading until the end.

I also plan to introduce the strange roasting methods I've done so far (like using a microwave up to about 150°C).
If you have any feedback like "It would be nice to have this feature" or "This part is hard to use," please let me know in the comments. (Realizing them might be difficult, though)
The coffee brewing app BARISTA-TIMER is being prepared for open-source (completely free) release so that anyone can register recipes.
Well then, have a wonderful coffee life today.
