About this app

Anchor watch is a position logger, Email/IM alarm and sound alarm and it monitors the device's current location and informs you if the location of the device changes too far away from the set anchor. In that case, it will sound an alarm and optionally send an Instant message or an email. (Pro version)

Please know that the performance and accuracy of the Anchor watch application depend on the hardware and software of the used device. If you have bad reception, please move the device to a location that has better satellite reception!

Because this application uses GPS to monitor movement, it will consume battery a bit faster than normal. We suggest you charge your device while using the app, although it's not necessary and the impact on battery life strongly depends on the specific device! There is also an advanced option to set GPS update intervals which might greatly improve battery life.

Application features:
  ♦  Shows GPS location and accuracy
  ♦  Monitors current distance to anchor
  ♦  Alerts you in case you drift too far from the anchor
  ♦  Alerts you in case you loose GPS signal
  ♦  Allows you to select a sound alarm
  ♦  Allows setting exclusion zones
  ♦  Uses device's compass to set the anchor even if you are not located directly above it

Please check out our Anchor watch PRO for additional features

The application requires the following permissions:
  ♦  Fine GPS location: To monitor your location
  ♦  Full internet access: For map view
  ♦  Network state: For Google AdMob
This application can be used on boats, sailboats, motorboats and any other objects that move freely.

In case of bugs:
All applications can have bugs, so if you find one, please inform us so we can solve the issue. You can also contact us if you have a suggestion for improving the app. We will gladly listen to your suggestions!

If GPS doesn't work, please bear in mind that it might be a hardware issue, as some devices have trouble getting a good GPS fix! We cannot do anything about that, nor can any other app.

If you want to post negative comments, PLEASE CONTACT US FIRST on as we would like to resolve the issue.

Some device types have problems with some parts of the application, such as not providing proper GPS provider. Since those are per-device issues, we cannot guarantee to support each one.

Please keep in mind that the application is provided "AS-IS". It should not be relied on to and we shall not be responsible for any problem/expense/life threatening situation it could cause.

  ♦  If the application keeps loosing GPS signal when screen is turned off, try disabling battery optimizations of the specific phone. If that doesn't help, try enabling the option in application settings to keep screen on. We are researching alternative solutions.

Originally I loved the app, easy to understand and use in every way, but the alarm kept going off all night. I widened the parameters significantly including delaying the alarm in case I lost the GPS signal and it continued to alarm seemingly for no reason. I decided to set the alarm when I was tied up to the dock. I couldn't have moved more than a foot, it eventually alarmed anyway. So I turned it off. I don't actually know if it was the app or my cheesy phone. I just know it didn't work.

Works exactly as advertised. The pro version is well worth the $5.99 for two reasons, the track line of the boats movement or history, and 2nd, the ability to receive notification either from email or telegram message. We leave the cell phone with the pro version of the app on the boat and take the other cell phone with us. The app takes 5 minutes to figure out, after that, it's simple to use. It's great piece of mind at night, you don't need cell service once downloaded, just the phones gps.
