Anchormee Alarm watches your anchor so you can sleep. Set the anchor, choose a swing radius, and the app keeps checking your GPS position all night. If the boat drifts outside the radius, a loud siren and a full-screen alarm wake the crew, even with the phone locked, the screen off, or the app swiped away.

WHY SKIPPERS TRUST IT
• Works fully offline. The alarm runs on your phone and needs no mobile signal.
• No false alarms from GPS noise. Accuracy is taken into account, and the siren only fires after a sustained breach, not on a single bad fix.
• Sirens through Do Not Disturb, with vibration and optional forced speaker output.
• Survives the night. A watchdog restarts the watch if your phone's battery manager stops it, and the watch resumes after a reboot.
• Low-battery warnings before the phone dies on you.

SET THE ANCHOR YOUR WAY
• Drop it at your current position.
• Enter a bearing and distance from where you stand.
• Type in GPS coordinates.
• Reuse the last anchor position.
• Advanced sector mode: a larger radius in one direction only, for example downwind or towards deep water.

SEE WHAT THE BOAT IS DOING
• Live distance, bearing, GPS accuracy and last fix time.
• Map with anchor, swing circle and the boat's minute-by-minute track.
• History of past anchorages.
• Night mode in red to protect your night vision.

WATCH FROM A SECOND PHONE
Share the watch with a QR code and a second device monitors the boat, for example from the dinghy, the cockpit or a crew member's bunk. The second phone raises its own alarm if the boat drags or if the connection is lost.

REMOTE ALERTS
Get drag alerts by email or Telegram. In Telegram, ask the bot for the current status or have it send a status update every few minutes.

DESIGNED FOR THE COCKPIT
• Metres or feet.
• Light, dark and red night themes.
• Keep-screen-on option.
• Hold-to-release so the anchor watch cannot be dropped by accident.
• Available in English and German.

PERMISSIONS
Anchormee needs precise location, including in the background, to keep watching while you sleep. It asks for notifications, full-screen alerts and an exemption from battery optimisation so the alarm can wake you. No account is needed and the app contains no ads or analytics.

An anchor alarm is an aid, not a replacement for good seamanship. Always keep a proper anchor watch in doubtful conditions.
