Drift alarm for anchoring
Download on the App StoreFeatures
Set your anchor point in one tap
Drop your anchor point from where you are with a single tap. VirtualAnchor tracks distance, drag speed, and direction from that point on a live-updating map.
Background monitoring
Background location tracking keeps watch even when the app is closed or the screen is off, alerting you the moment your boat drags outside your set radius.
Voice alerts and auto-anchor
Voice notifications read out the distance at your chosen interval, so you don't need to keep watching the screen. Auto-anchor detects when your boat has stopped and sets the anchor point automatically.
Review the map afterward
Switch between standard and satellite maps anytime. Past anchor points and drag trails stay on the map, so you can see where you anchored and how far you drifted.
Set your own alert radius
Choose your alert radius in meters, kilometers, or nautical miles. Adjust it for a quick lunch stop or an overnight anchorage.

FAQ
Does monitoring continue if I close the app?
Yes. VirtualAnchor supports background location tracking, so it keeps watching and will alert you if your boat drags outside your set radius even when the app is closed or the screen is off.
Does VirtualAnchor replace a boat's anchor drag alarm?
No. VirtualAnchor is a monitoring aid and does not replace continuous anchor watch, proper rode length, or a dedicated anchor drag alarm on your vessel. Always practice safe seamanship.
Is there a subscription?
No. VirtualAnchor is a one-time purchase with no account required and no ads. Once purchased, you can use it on every trip.
Does it work on iPad?
Yes. VirtualAnchor supports both iPhone and iPad.
