Why Slot.SG

Spontaneous fitness, finally made easy.

Real-time slots

Only classes that are actually open right now — no dead listings, no guesswork.

Near you

Sorted by distance, so a great class is always within reach across the island.

No membership

Pay per class, cancel nothing. Perfect for travellers, trials and busy weeks.

Fills the room

For operators, every empty spot becomes revenue — and a shot at a new regular.

The idea

Every empty spot is a missed workout — and missed revenue.

Classes run half-full while people nearby scroll for something to do tonight. Slot.SG closes that gap in real time, matching open spaces to the people who want them.

Launching soon
