Tidewatch
A tide-table app for the Vancouver harbour, designed to be read in one glance.
The problem
The printed tide table at the Vancouver harbour is dense and hard to read in bad light. Skippers wanted one number: when is the next high tide?
The approach
I interviewed six local skippers and sketched three layouts. The final design leads with a single large time and a simple rising/falling curve, with the full table one tap away.
The outcome
A local boaters' group adopted Tidewatch, linking it from a QR code at its clubhouse. Testers found the next high tide in under three seconds.
