SeaThrough combines key signals like tide movement, swell, and wind into a simple, glanceable forecast so you can spend less time researching and more time in the water. Features: • Map-based spot discovery with pinning and favorites • Hour-by-hour clarity forecast and visibility range • Tide direction and timing insights • Quick planning with saved spots and planned dives If a location’s data isn’t available yet, you can request it in-app. Requested locations will be prioritized and added in future releases.

- More accurate water clarity readings: current conditions now match the hourly forecast for the same hour, with a refined tide-slope adjustment. - Water temperature in hourly forecast is now correctly shown in °F. - Better handling when a buoy is partially down — falls back to modeled conditions instead of going blank. - Faster refresh on the Planned tab and a Try Again option when network hiccups interrupt loading.
