This app duplicates the MOB button on your Chartplotter. It works without an iPhone or internet connection and can be launched with one touch on your Apple Watch. It takes a GPS point at the sea according to your direction and speed, and time delay for finding the signal. This way it always saves the exact GPS point where you pushed the button. It is constantly showing the true course to the point, distance to the point, and time at the water, since the point was set. The graphics in the app will help you see your position towards the point. If you fail to pick the person from the water you can correct his position by resetting position, while passing by. This application can provide essential assistance during training MOB on the water, especially at night or in restricted visibility conditions. All the coordinates are saved in the Watch memory and will be uploaded to iCloud. This way the last point is always saved in the memory of the watch and you will get your data even after the app restart.

Verdict
The clearest difference is update cadence: MOB at every 4 days against Anchor Plus's monthly. MOB also leads on rating (5.0 vs 4.7) and iOS requirement (13.0 vs 17.6). Anchor Plus's advantage is ratings volume (7 vs 1). 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
Anchor Plus costs $1.99 and MOB $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
MOB holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Anchor Plus has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Anchor Plus ships an update monthly, MOB every 4 days. Both last shipped on October 25, 2026.
