Tidewell: Tide Times & Chart app analytics for September 1

Tidewell is a calm, offline-first tide app for the coast — precise high and low tide times, a live tide curve, and gentle alarms for thousands of coastal stations worldwide. No account. No sign-in. Tide times work with no signal at all. Every prediction is computed on your device with the standard harmonic method, using open tide-harmonic constants from NOAA and the TICON global tide dataset.
