Stim Check

Stim Check is a lightweight utility that helps you monitor how much caffeine is active in your body so you can time intake for better performance, workouts, and sleep. The app lets you quickly log coffee, pre-workout, or energy drinks and uses your body weight plus caffeine half-life to produce a real-time caffeine curve. You’ll see how much stimulant remains at any moment and get a “clear by” time indicating when levels drop below a sleep-safe threshold. Its straightforward design aims to make caffeine tracking fast and easy to include in your daily routine.
