Why 7III Water?

Many foiling and water sports tracking apps depend on recurring payments. 7III Water takes a different approach:

Tracking your sessions should not require a subscription. The free version includes your 30 most recent sessions, and the GOAT upgrade is a one-time purchase that unlocks the full app forever. Optional monthly and annual plans are also available for riders who prefer them.

Choose the lifetime unlock and avoid recurring fees.

No subscription traps.

Just a fast, beautiful foil tracker that helps you spend more time on the water.

How do you pronounce 7III Water?

7III Water /sĕv′ən thrē wô′tər, wŏt′ər/

noun
The 7III comes from project7III, which is project, seven followed by three i's. Spoken out loud, that becomes project seven three.
We turned 73 into a modern text logo, very 21st century, and admittedly to confuse people along the way.
