► SCOPE CALCULATOR
Enter depth, bow height, and scope ratio to get recommended rode length. Supports chain, rope+chain, and rope. Get wind-based scope suggestions and warnings when you don’t have enough rode.

► ANCHOR DRAG ALARM
Set your anchor point with GPS and choose a drag threshold. Get audio and vibration alerts if your boat moves beyond the limit. Background monitoring keeps the alarm active when the app is in the background.

► SWING RADIUS & MAP
See your swing circle on the map with anchor point and current position. Check distance and bearing in real time so you know you’re staying in a safe radius.

► BOTTOM TYPE & ANCHOR GUIDE
Pick bottom type (sand, mud, rock, etc.) for suitability hints. Use the anchor guide to compare anchor types and the step-by-step guide to anchoring technique.

► SESSION HISTORY & SETTINGS
Save and review past sessions. Use metric or imperial units. Adjust default scope, drag threshold, and alarm sound to suit your boat and conditions.

Anchor Aid is a tool to support good seamanship - not a replacement for keeping a proper watch or using official charts and equipment. Always use your own judgment when anchoring.

Built for boaters who want a clear, practical anchoring assistant. ## Rankings - #2,704,002 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_BACKGROUND_LOCATION` - `android.permission.ACCESS_COARSE_LOCATION` - `android.permission.ACCESS_FINE_LOCATION` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.FOREGROUND_SERVICE_LOCATION` - `android.permission.INTERNET` - `android.permission.MODIFY_AUDIO_SETTINGS` - `android.permission.POST_NOTIFICATIONS` - `android.permission.READ_APP_BADGE` - `android.permission.READ_EXTERNAL_STORAGE` - `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` - `com.anddoes.launcher.permission.UPDATE_COUNT` - `com.android.vending.CHECK_LICENSE` - `com.feleroid.anchoraid.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` - `com.google.android.c2dm.permission.RECEIVE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` - `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 Spot](https://chrome-stats.com/d/com.anchorspot) — 132 users - [AnchorSafe – Anchor Alarm](https://chrome-stats.com/d/com.canalitech.anchorsafe) — 994 users - [Anchor Easy: GPS Anchor Alarm](https://chrome-stats.com/d/com.anchoreasy) — 2,309 users - [Seahorse Anchor Alarm](https://chrome-stats.com/d/com.ap4.anchor_alarm_mobile) — 3,733 users - [Anchor Alarm Pro](https://chrome-stats.com/d/com.anchoralarmpro.app) — 524 users - [Anchor Sentry](https://chrome-stats.com/d/de.sioned.anchorsentry2) — 454 users - [AnchorChainCalculator](https://chrome-stats.com/d/de.trimaran_san.anchorchaincalculator) — 432 users - [Anchor Alarm](https://chrome-stats.com/d/de.whsoft.ankeralarm) — 92,543 users, 4.49 / 5 - [AnchorWatch](https://chrome-stats.com/d/hu.anchorwatch.app) — 123 users - [Anchor Alarm - SailGrib AA](https://chrome-stats.com/d/com.sailgrib.anchoralarm) — 41,828 users, 4.17 / 5 - [Dr.Anchor](https://chrome-stats.com/d/com.drgadgets.dranchor) — 973 users - [Anchor Watch Lite](https://chrome-stats.com/d/net.fs.android.anchorwatchfree) — 38,171 users, 3.25 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.feleroid.anchoraid)
