## Review summary

The PNW Current Atlas app is praised for visualizing currents and planning with hourly forecasts and offers strong value as a one-time purchase. It supports hourly scanning and has responsive developer support. However, reviews note price concerns, incomplete geographic coverage, occasional time offset/DST issues, and missing important currents or predictions in key areas. Overall, it’s a useful planning tool with caveats about data scope and accuracy.

### Pros

- Easy to visualize currents and plan trips with hourly forecasts.
- Good value for the price: a one-time purchase around $20 that can save hours versus buying/updates of the paper atlas.
- Hourly current scanning/forecast capability (hour-by-hour) helps navigation.
- Developer responsiveness and willingness to explain data/algorithms.

### Cons

- Price/value concerns: perceptions that $19.99 is high for the app's scope.
- Limited geographic coverage: not all Puget Sound and eastern waters are included; missing key charts.
- Time accuracy issues and DST handling: some reports of 1-hour offset and no DST corrections.
- Missing important currents/data points and some regions lack predictions (e.g., Deception Pass, Nanaimo, etc.).
