Ratings and Reviews
Are times corrected for Daylight Savings Time?
The developer does not say. Overall a good tool but a prudent mariner should cross check the physical book and annual supplement. This app is developed with data from CHS. They do not correct for DST. From observations, I suspect times are UTC + 8.
Developer Response ,
Yes it is corrected for daylight savings time and that information is available on the app support page. We will add it to the app description in the next update.
Great Resource
At one point I was using the app and I found what I thought was an error since there was a disagreement between the paper current atlas and the app. I recorded the time and the referenced pages and reached out to the author of the app. He wrote several emails explaining the additional algorithms used for the app, and how since the paper atlas is by hour is often doesn’t show small reversals and other small changes. He walked me thru the data used and how his app presents the analysis. I won’t stop referencing the paper current atlas but I will use this app as well. Randall
Brilliant
I sail a small boat in these waters, and depend on the Canadian current atlas for every trip. This implementation is fantastic. And since you have to buy an update to the printed atlas every year for $20, the once off price for the app is well worth it. The app also lets you scan the currents hourly, instead of paging through the printed guide. Very impressive.
