A free app for Android, by HCSoft S.L..
Sailsafe is a handy app that will increase your safety when anchoring your ship. It works as an alarm and a navigator. The alarm will notify you in case your ship leaves a safe area, which is very common. In order to set a safe area, you need to enter the exact coordinates of the location and choose a radius for the safe area. The app has a user-friendly interface, which makes it easy to use.
If you want to be more comfortable when using Sailsafe, you can use the PRO version of the app. It has an ad-free version and an offline mode.
