The caffeine calculator is what sold me—being able to dial in exactly how much I need for a mid-afternoon cup without lying awake at 2 a.m. has genuinely changed my coffee routine. I've dialed it down on weekends and it's been a game changer.

I was skeptical that I could keep my late-night work sessions without wrecking my sleep, but the caffeine calculator actually nailed it. I set my desired cutoff and the suggested amount per cup was spot on — I'm sleeping through the night for the first time in weeks.

The caffeine calculator let me dial in exactly the right strength for my afternoon slump, and I've actually been sleeping better since I switched. First cup tastes clean and smooth, no bitter bite on the finish.
