"DriftWatch Lite" has all the features of "DriftWatch". The only exception is that it monitors your location for a limited time. "DriftWatch" has no limitation. Download it from the AppStore.

DriftWatch is a captain's best friend for a good night of sleep. Often the captain sets anchor for the night and keep waking up regularly to confirm that the anchor is still preventing the boat from drifting.

Some boats/yachts have anchor alarm on their GPS system. Unfortunately, it is not rare that the integrated GPS system is inaudible from the captain's bed.

With DriftWatch running on your IOS device, you can have it near your bed and be confident that it will warn you if you drift outside of the established boundary.

DriftWatch is the perfect complementary mean that provides peace of mind when anchored.

DriftWatch is simple and easy to use.
