About this app
This is a tool to help you sleep better while at anchor. Set your anchor position, define a radius, and start the anchor watch. If your phone is persistently outside the defined radius it will start to ring loudly.
In contrast to other anchor apps this one comes without any other feature and without ads. It also doesn't need internet connection. The only focus here is having a reliable anchor watch.
No false alarms - Your phone's GPS is not always as accurate as you think. When you set the alarm radius you will see the GPS error. Use the length of your chain/rode plus twice the error to avoid false alarms. To further reduce the chances of false alarms I implemented a counter which will count up on out-of-bounds readings. Only with multiple consecutive out-of-bounds readings the alarm will start.
Reliability - The active anchor watch shows a notification on your screen. However, many android devices suspend apps after several minutes of inactivity. This website explains these problems for different manufacturers: dontkillmyapp.com. Notably, you need to make sure that the Battery Saver does not suspend this app after some minutes of inactivity.
Privacy - This app does not download anything and does not send anything. It only requests the geolocation every 5s and compares it. Nothing is saved.

What's new
An update in the way how out-of-bounds measurements are counted makes the anchor watch more specific and a little less sensitive: It takes a few seconds longer for it to start sounding an alarm when the anchor is truly dragging. But on the other side, it is less likely to create a false alarm if the anchor is not dragging.
I also added a little reminder about the energy saver and other things how the phone might try to kill the app if not in use. The reminder pops up after the app opens.
