Anchor Alarm - The anchor guard for your boat Get alerted as soon as your ship aborts. Set the radius and click on Start to start the anchor alarm. As soon as your ship leaves the radius, your device alerts you with an unmistakable alarm tone. In addition, you can move the monitored area and correct it to the nearest meter. The location history of the boat is recorded and can be seen from the small points. With our remote monitoring feature, you can connect two devices together. The sender remains on the boat while you are on land. As soon as the sender leaves the area you will be alerted on the way.

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.

Both are free to download. Anchor Alarm / Watch sells 5 in-app purchases, starting at $3.99 per year and SailTimer API™ sells 6 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
SailTimer API™ holds the better App Store score, 5.0 against 4.7.

Written reviews complicate that: 55% of Anchor Alarm / Watch's written reviews are positive against 0% of SailTimer API™'s, so the app with the better star average is not the one people write more warmly about.
Anchor Alarm / Watch ships an update every 3 weeks, SailTimer API™ every 4 weeks. The most recent releases landed on September 24, 2026 and August 19, 2026 respectively.
