What's an iPhone owner to do?
Shralp Tide - an app dedicated to just this purpose. Based on the gold standard XTide software and ported to run in the IOS environment, Shralp Tide makes tidal predictions all over the world available right there on your iPhone/iPad.
Everything you need is right there on the screen -
- Current tide height
- Direction of movement (ebb/flood)
- Times of next/prev high and low tides
- Heights of next high and low tides
And two very key features:
- It's free.
- No internet connection is required.
Oh, and did I mention that it's free?
But if you are willing to pay a paltry 99¢, you get an improved version that also includes tidal current predictions. I've been using the free version for years, but because tidal currents are a big part of navigating Puget Sound, I recently went to the paid version. They're both excellent.
And you never know when you might need to have this app... last Saturday while working in the garage, I got a call from my son. He and his wife were hiking Washington's wild Pacific coast and needed to know when the next high tide was coming in order to decide whether to round a headland with a minimal beach. Shralp Tide provided me the information while standing there covered with grease and a long way from the boat and her GPS or a tide booklet, because it was right there in my hand, on my phone.
