ANCHOR! APP FOR IPHONE AND IPAD WARNS YOU IF YOUR ANCHOR DRAGS
Designed by a skipper, Anchor! is intuitive and easy to handle :
1) set up your anchor position: slide the alarm circle where you want it to be with your finger tip,
2) adjust its size by sliding the edge of the circle,
3) and now relax, Anchor! is monitoring your position
By default, Anchor! warns you with a ring tone associated with an eye catching blinking screen. You can also choose to be alerted by an email or a phone call.
Moreover, Anchor! can monitor your position remotely. Even ashore you can check your boat’s position and be alerted.
