01 / Challenge

Researchers were still writing readings on waterproof paper and typing them up at night. Existing apps had tiny controls and assumed a desk, not a deck.

02 / Approach

We designed one-thumb logging with huge targets, haptic confirmation and an offline-first sync. The interface goes high-contrast automatically in bright sun.

03 / Results

−70%

time spent logging per dive

0

lost readings since launch

140

researchers in the first year

“It is the first tool on the boat nobody complains about.”

Dr. Sofia Reis — Lead researcher
