This app allows you to use SailTimer products in other partner apps. First, if you have the wireless SailTimer Wind Instrument (www.SailTimerWind.com), this app can receive the transmissions and deliver them to other apps for viewing. Use this app with the the SailTimer™ chartplotter app, or with lots of other navigation, wind gauge or performance apps (https://wi-rb.com/apps/). But what if you want to see what the wind is doing up ahead, or around the next point? Then you need our crowdsourced wind maps and marine weather animations. You can get the low-cost subscription here, to view our marine weather animations in partner apps. We'll add a growing list of partner apps at https://SailTimer.boats App web page: https://wi-rb.com/api. If you have a question or feedback please email info@SailTimer.co - we’re here to help. If you are getting the app and like this wireless technology, please help out other sailors by letting them know with a quick rating on this version while you’re here. ## Key features - Integrates with SailTimer Wind Instrument - Delivers wind data to partner apps - Crowdsourced wind maps - Marine weather animations - Supports chartplotter apps - Real-time wind data ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Crowdsourced Wind Maps - Yearly | $19.99 | per year | | Crowdsourced Wind Maps - Monthly | $2.99 | per month | | WNI Marine Weather - Yearly | $19.99 | per year | | WNI Marine Weather - Monthly | $2.99 | per month | | AI Forecasts - Yearly | $19.99 | per year | | AI Forecasts - Monthly | $2.99 | per month | ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/sailtimer-api/id1562869275/reviews.md ### 1/5 — Waste of time and money *2024-08-02* I spent 10 months waiting for a wind instrument to turn up after purchasing. Then it was faulty as it would only send battery and temp data 90% of the time. Spent many unsuccessful hours trying to get it to work reliably. ### 1/5 — What happened? *2022-09-21* Not working on iPhone since update a month ago. Still waiting for fix… **Developer response:** Thanks for your comment. Feel free to contact Technical Support at info@SailTimerinc.com if you want to know what is happening with an update. Version 2.4 of this app has now been submitted to the app store. It took a lot of testing to replicate a bug and understand when it was occurring, and then to make adjustments in the software and test that the corrections were successful. This takes time. Ordinarily we can make changes quickly, but this one required many iterations and could only be tested when underway with GPS movement. We worked on it every day, and appreciate your patience until that was completed. Happy sailing! ## Frequently asked questions about SailTimer API™ ### What is SailTimer API™?
