Tide Pro vs 神舟地球导航
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Tide Pro
This app provides high-precision forecasts for ocean weather, including astronomical tides, storm surges, and merged ocean currents. It offers detailed data on wave conditions, ocean currents at various depths, and marine bio-chemistry. Users can also access seabed elevation and field water/soil temperatures.

Tide Pro was developed by www.9oc.net and published in September 2020. If you are into fishing, beach combing, surfing, sailing, or wild fishing, this app provides high-precision ocean weather forecasts. Main benefits: 1. Astronomical tide and currents forecast: The tide model algorithm was upgraded in January 2021, and grid precision was significantly improved compared with the previous model. Supports offline access to real-time tide and moon phase data for favorite sites. 2. 6-day storm surge forecast: Storm surge is the rise in seawater level caused solely by a storm. It is measured as the height of the water above the normal predicted astronomical tide. This model output is not total water level guidance. Total tide results from the combination of storm surge and astronomical tide. Actual water levels can be significantly higher than forecast due to waves, steric effects, and other components not currently included in this model. 3. Merged ocean currents provide a practical estimate of sea-surface velocity. The total current is obtained by adding contributions from general ocean circulation, waves such as Stokes drift, and tides, including exchange between the coast and the open sea. Supports access to the speed and direction of merged ocean currents, oceanic general circulation, sea surface height, and sea surface temperature. 4. Ocean wave forecast: Supports access to wave height, wave period, wave direction, and three categories of wave data. 5. Ocean currents forecast: Supports access to current speed, direction, temperature, and salinity data for both surface currents and currents at 50 different depths. 6. Ocean biochemistry forecast: Supports access to 10 marine biochemistry indicators, including chlorophyll, phytoplankton, pH value, and gross primary productivity. 7. Seabed elevation: Supports access to seabed elevation data. Grid precision is less than 0.5 km. 8. Weather data including water temperature and soil temperature: Supports access to water temperature and soil temperature at four different depths. Please note: We cannot guarantee the accuracy of numerical forecasts and provide this information for reference only.

Verdict
The clearest difference is rating: Tide Pro at 5.0 against 神舟地球导航's 4.4. 神舟地球导航's advantage is ratings volume (102 vs 3) and update cadence (fortnightly vs every 2 months). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Tide Pro sells 2 one-off in-app purchases and 神舟地球导航 sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Tide Pro holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: 神舟地球导航 has 102 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 38% of Tide Pro's written reviews are positive against 39% of 神舟地球导航's, so the app with the better star average is not the one people write more warmly about.
Tide Pro ships an update every 2 months, 神舟地球导航 fortnightly. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
