Know the instant you start drifting
VirtualAnchor turns your iPhone into a GPS anchor watch. Drop a virtual anchor, pick an alert range, and get a loud alarm the moment your boat drags off the mark — even while you're asleep.

Everything VirtualAnchor does
Virtual anchor & drag alarm
Tap once to drop a virtual anchor at your current position. If your boat drifts beyond the range you set, VirtualAnchor sounds a loud, critical alert so you can react before things get dicey.
Adjustable alert range
Set the exact swing radius for your spot — from a tight berth to a wide open anchorage. Enter it in metres, kilometres or nautical miles.
Live distance, speed & heading
See how far you've moved from the anchor, how fast you're drifting and in which direction — all updating in real time. Switch units between m / km / nm and m/s / km/h / knots.
Auto Anchor
Let the app set and clear the anchor for you. It keeps an eye on your speed and automatically drops the anchor when you settle in to moor, and releases it when you get under way again.
Voice distance alerts
Choose an interval and VirtualAnchor speaks your drift distance out loud, so you can keep your eyes on the water and your hands free.
Lock Screen Live Activity & Dynamic Island
Keep distance, speed, heading and elapsed time live on your Lock Screen and Dynamic Island. Check your status at a glance without ever opening the app.
Apple Watch companion
Read distance, speed, heading and elapsed time right from your wrist. Perfect when your phone is tucked away in a dry bag below deck.
Satellite & standard map
Switch between a clean standard map and a realistic satellite view to read the shoreline, reefs and the water around you with precision.
Track & route history
Your drift path is drawn live on the map, and previous tracks are kept so you can see exactly how your boat moved through the night.
Watch the drift from your wrist
The Apple Watch app mirrors distance, speed, heading and elapsed time so you can keep monitoring with your phone safely stowed away.
What people use it for
VirtualAnchor isn't only for sleeping at anchor — anywhere holding your position on the water matters, it helps.
Anchor drag watch
Sleep or relax at anchor knowing you'll be woken the instant the boat starts dragging towards the shore, rocks or another vessel.
Boat fishing drift monitor
Watch how far and how fast you drift off a wreck, reef or mark. Know exactly when to motor back up onto the spot.
Surf line-up position keeping
Hold your place in the line-up. A quick glance tells you how far the current has pushed you off your peak.
SUP & kayak position hold
Stay over your favourite paddling spot or fishing hole and notice straight away when wind or tide carries you off.
Sailing & mooring
Confirm your swing room before you settle in, and get warned if your mooring or anchor starts to give way.
Tidal & current awareness
See your real speed and heading over the ground to understand how the current is setting you, even when you feel still.
Kayak & float-tube angling
Lightweight craft drift fast. Keep tabs on your position so you fish the spot, not the next bay over.
Holding a spot on the water
Whether you're filming, diving, swimming or just enjoying a view, mark the place and know the moment you drift off it.
