Not so great
Times are given in standard time with no correction for daylight savings and so will be off by an hour. In addition, interpolated tide heights between highs and lows are not accurate. I am a marine biologist and use tide charts, apps, etc. in my work and have done so for over 30 years. This app is not good so still looking for a good one to be on my menu bar for quick reference. I use Mr. Tides and the NOAA wedsite if I need more detail.
