FlowCoach
Stay focused for longer.
You sit down to work. Twenty minutes later you're four tabs deep in something else and you're not sure when that happened.
FlowCoach is a small menu-bar app for your Mac. Tell it what you're working on, and it quietly watches which app or site is in front, then nudges you once you've drifted.
Everything stays on your Mac. No network connections, no screenshots, nothing uploaded, ever. Export or erase everything it records whenever you want.
FlowCoach is in closed beta. Leave your email and you'll get a download link.
Requires macOS 15 (Sequoia) or newer.
