Tideline is for a spot on the coast and the evening ahead. It shows sunset, the tide curve with today's observed water level drawn over the prediction, wind, temperature, sky and moon, all on one time axis, for any of the next 14 days.
It shows the data and leaves the decision to you, with no scores and no alerts. You can save your own spots anywhere in the US, share one as a link, and add it to an iPhone home screen.
It came in through iBuild4You and went from an empty repo to a live site in a day. Since then it has grown in short rounds of feedback. Tides come from NOAA stations, weather from the National Weather Service and heights from USGS. Sun and moon times are computed in the browser.
