Tide Metronome
Exchange the tide. Meet over the pearl.
Swap the speed of two waves, time their meeting over a pearl and grow a luminous reef shaped by the way you play.
A reef from every tide
Use one repeated action, judge the meeting and keep the reef you grow.
- Swap two moving wave speeds with one tap.
- Build a score or play without lives.
- Use Step mode for an untimed route.
- Keep favourite reefs and share an image when you choose.
One tap changes the tide
Two waves move towards a pearl at different speeds. Swap their speeds while they travel and try to bring them together over the pearl.
Endless
Build a score and grow your reef until three tides drift past.
Daily tide
Play the same eight-round challenge for the day and try it again whenever you like.
Calm
Play without lives or a forced ending. Finish the reef when it feels complete.
Your timing grows the reef
A closer meeting creates stronger coral growth. Keep recent reefs on your iPhone, pin your favourites and share a detailed reef image when you choose.
Play your way
Step mode offers an untimed route through a Calm tide. Sound, music, haptics and gentler visual movement can all be adjusted in Settings.
