ZenDepth

Master your breath. Extend your limits.

ZenDepth is a personalized apnea training app built for freedivers, spearfishers,
surfers, and meditators who want to go further underwater.

Set your baseline. Get a 12-session adaptive plan calibrated to your personal best. Track
your progress through phases as your hold times grow.

oxygen more efficiently. Every plan adapts to your current level and improves with you.

exercises — guided in real time with live cues.

UNLOCK TECHNIQUES

GAMIFIED MILESTONES
Earn badges, conquer phases, and watch your guided streak grow. Training feels like
progress, not a grind.

Add friends by username and see how your personal bests stack up. A private leaderboard
built for the freediving community.

BEAUTIFUL BY DESIGN
An underwater aesthetic that makes every session feel like a dive. Animated backgrounds,
glass-morphic UI, and haptic feedback designed for focus and flow.
