⚓ ANCHOR ALARM
Sleep soundly at anchor: drop your anchor point, set the swing radius and let ClearShip watch your position – even in the background. You get an early warning when you approach the threshold and a full alarm if your boat leaves the radius.

🆘 EMERGENCY & MAYDAY
The emergency assistant guides you step by step through Mayday and Pan-Pan radio calls – with your current GPS position, boat name and MMSI. Includes the NATO phonetic alphabet so you find the right words when it matters.

🧭 TOOLS FOR ON BOARD
• Compass & GPS – heading, position and speed
• OpenSeaMap – nautical chart with navigation data
• NMEA 2000 reader – live data from your WiFi gateway
• Navigation calculator – course, leeway, current triangle, ETA
• Anchor calculator – rode length and scope
• Sail trim – trim recommendations for main and headsail
• Wind converter – Beaufort, knots, m/s, km/h
• Unit converter – nautical and standard units
• Weather charts – DWD surface weather charts
• Phonetic alphabet – NATO alphabet reference

🛥️ BOAT MANAGEMENT
• Tasks – plan, prioritize and check off maintenance work
• Logbook – voyage entries with position and course
• Checklists – e.g. for departure, maintenance or winter storage
• Equipment – devices, manuals and maintenance schedules
• Inventory – equipment and spare parts with photos
• Expenses – track costs and receipts
• Documents – boat papers and manuals, available offline on board

📡 OFFLINE-FIRST
There is not always reception on the water. ClearShip is built for that: tools work offline, pinned documents are stored locally, and your data syncs as soon as you are back online.

🔄 SYNC (OPTIONAL)
With a free ClearShip account you sync boats, tasks and logbook across all your devices. All tools also work entirely without an account.

🌍 Available in English and German, with light and dark mode.

Note: The anchor alarm uses your location in the background while it is active. ClearShip is an aid on board – it does not replace a proper anchor watch, official nautical charts or good seamanship. ## Rankings - #3,036,034 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_BACKGROUND_LOCATION` - `android.permission.ACCESS_COARSE_LOCATION` - `android.permission.ACCESS_FINE_LOCATION` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.ACCESS_WIFI_STATE` - `android.permission.ACTIVITY_RECOGNITION` - `android.permission.CAMERA` - `android.permission.FOREGROUND_SERVICE` - `android.permission.FOREGROUND_SERVICE_LOCATION` - `android.permission.INTERNET` - `android.permission.POST_NOTIFICATIONS` - `android.permission.READ_APP_BADGE` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.RECORD_AUDIO` - `android.permission.SYSTEM_ALERT_WINDOW` - `android.permission.VIBRATE` - `android.permission.WAKE_LOCK` - `android.permission.WRITE_EXTERNAL_STORAGE` - `app.clearship.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` - `com.anddoes.launcher.permission.UPDATE_COUNT` - `com.android.vending.CHECK_LICENSE` - `com.google.android.c2dm.permission.RECEIVE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.htc.launcher.permission.READ_SETTINGS` - `com.htc.launcher.permission.UPDATE_SHORTCUT` - `com.huawei.android.launcher.permission.CHANGE_BADGE` - `com.huawei.android.launcher.permission.READ_SETTINGS` - `com.huawei.android.launcher.permission.WRITE_SETTINGS` - `com.majeur.launcher.permission.UPDATE_BADGE` - `com.oppo.launcher.permission.READ_SETTINGS` - `com.oppo.launcher.permission.WRITE_SETTINGS` - `com.sec.android.provider.badge.permission.READ` - `com.sec.android.provider.badge.permission.WRITE` - `com.sonyericsson.home.permission.BROADCAST_BADGE` - `com.sonymobile.home.permission.PROVIDER_INSERT_BADGE` - `me.everything.badger.permission.BADGE_COUNT_READ` - `me.everything.badger.permission.BADGE_COUNT_WRITE` ## Similar extensions and apps - [Anchor Alarm & Emergency Tides](https://chrome-stats.com/d/com.alert.boat) — 309 users - [Seahorse Anchor Alarm](https://chrome-stats.com/d/com.ap4.anchor_alarm_mobile) — 3,884 users - [SeaBase](https://chrome-stats.com/d/com.yeomanventures.seabase) — 3 users - [Skipper: Boat & Sailing Log](https://chrome-stats.com/d/tk.ivpe.logbookskipper) — 173 users - [Anchor Easy: GPS Anchor Alarm](https://chrome-stats.com/d/com.anchoreasy) — 2,377 users - [Sail Expert: Sailing App](https://chrome-stats.com/d/com.poterion.logbook) — 88,352 users, 4.24 / 5 - [Navigation Tools Nautica](https://chrome-stats.com/d/com.morris.navigationtools) — 61 users - [BlueHelm Boating](https://chrome-stats.com/d/com.bluehelm.anchorwatch) — 10 users - [Safe Skipper - Boating Safety](https://chrome-stats.com/d/free.skipper.biz) — 1,085 users - [EasySail](https://chrome-stats.com/d/com.geektheory.sailnavapp.navapp) — 1 users - [Salt and Wire Companion](https://chrome-stats.com/d/com.saltandwire_companion) — 48 users - [OceanPilot: Sailing Navigation](https://chrome-stats.com/d/com.oceanpilot.app) — 50 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/app.clearship)
