SitLess reminds you to stand up and take breaks while you work — without being annoying about it. Set your reminder interval (25–90 min). When it's time, a gentle overlay appears with a countdown. Webcam detection automatically pauses the timer when you step away, so you only get reminded when you're actually sitting. Features: • Smart timer • Webcam AI motion detection • Daily streaks & 9 achievements • Meme mode 😄 • 11 languages • 100% free, no account needed
