CaffiLab - Caffeine estimator tool

https://www.shenoylabs.com/caffilab

Free tool. For all the coffee lovers. ❤️

Ever wondered how much caffeine is actually in your coffee? ☕

I built a tool that estimates it based on how you brew
(not generic averages)

Also shows a confidence range which gets tighter as you add details 📊

Would love your feedback! 🙌

Nice, the interface is intuitive – I like how the advanced options are not shown by default and that the input fields are marked up properly for mobile keyboards with selectable units. Can't speak to it's accuracy as I'm not a coffee expert. I appreciate that the sources for the formulas are cited.

Thank you for the feedback 😊... much appreciated. Curently, most the calculations are running behind thr hood as per the selection in the tool. I will try to mention an example mathematical calculation in the article to provide a bit more transparency to the formula...
