Urge Surfin tracks one thing: how many days you've stayed clean. Choose the habit you need to quit. Start your count. When a craving hits, you have somewhere to go. Urge Surf — draf the surfer to stay balanced on a wave. Urge surfing is a real DBT technique: cravings peak and pass, usually within minutes. The game holds your attention while that happens. Box Breathing — a guided breathing exercise for when you need to come down fast. Four counts in, hold, out, hold. Clinically simple. Actually works. Track your clean days with honest timestamps. Log daily check-ins so you can see patterns, not just streaks. No grace days. No second chances built into the math. Just your real count.
