About this app

Captain's Log is the digital logbook for sailors, skippers and boat owners. Record passages with GPS, use an anchor watch with alarm, manage maintenance, checklists and important boat documents – all in one app, directly on your smartphone or tablet. Works offline too.
⚓ Document passages easily
Start and end trips with just a few taps. Log route, times, engine hours, weather data, sail configuration and personal notes – all in one place. Your digital logbook is always with you, whether you're sailing the Mediterranean, the Baltic or the Atlantic.
