A: In the FREE version, you get 5 minutes of haptic vibration. You can upgrade to full access haptic vibration nudges with extended durations. Q: How does the No, Don't Do It app work? A: Simple. Before you enter a triggering situation, select the behavior you want to interrupt and the amount of time to be nudged, and start. The haptic vibration will remind you every so often of what you want to avoid doing, from 15 minutes to 1 hour in your Apple Watch or iPhone. Q: Do I need an Apple Watch? A: No. While Apple Watch provides the ideal discreet wrist-based experience, your iPhone's Taptic Engine delivers equally effective private haptic vibration.

Instead of logging failures, we provide real-time intervention for self-control and behavioral change at your moment of choice. Q: What situations work best? A: Situational behaviors triggered by specific contexts (parties, meetings, shopping, social events) respond exceptionally well to just-in-time intervention and pre-situational setup. Q: Are these like notifications? A: No. Unlike notifications that require you to take action. No, Don't Do It uses private and gentle haptic vibrations.
