Coffee Cutoff is a small, focused iPhone utility for people who love coffee but don’t want to guess whether it’s too late in the day. Set your bedtime, choose your usual drink, and Coffee Cutoff estimates your daily caffeine cutoff. It gives you a simple answer: you’re clear, you’re close to the cutoff, or it’s time to switch to decaf. Built to be private and simple: no account, no subscription, no social features, no backend.
