iPhone
Mareva turns daily neck stretches into a deep-sea adventure.
Your phone's front camera follows the tilt of your head. Tilt to steer your ship, hold the stretch to dive deeper, and bring back treasure from an alien ocean.
HOW IT WORKS
• Tilt your neck left and right to steer
• Hold the stretch to keep your ship moving
• Finish a dive to open treasure chests
• Come back each day and go deeper
WHY YOU'LL KEEP COMING BACK
• A ship AI coach counts with you and keeps you on pace
• Short sessions that fit a work or study break
• Streaks and personal bests show your progress
• Hand-crafted pixel art and calm ocean music
MADE FOR
• Desk workers and students who sit for hours
• Anyone who wants a simple daily neck routine
• People who find regular stretching boring
Stretch gently and stop if you feel pain. Mareva is a wellness game, not a medical device, and does not diagnose or treat any condition. If you are recovering from an injury, check with your doctor or physical therapist first.
