Head out.
Start your journey and put your phone away. Underway records your route, distance, speed and time.
The logbook for your time on the water
Record boat trips, import your GPX tracks, and keep your routes and notes in one logbook


Start your journey and put your phone away. Underway records your route, distance, speed and time.
Auto-stop finishes the recording when Underway detects your arrival. You can also end it yourself.
Open your log to see where you went and add a few notes while it’s fresh.

I thought I’d mostly use this for recording routes but I’m enjoying looking back through the logbook more than I expected. You forget the details of individual days out quite quickly, so having the trips there with a few notes is nice. Really enjoying it so far!

I spend most summers sailing around the Pacific Northwest. I wanted a boating app that’d be as useful on the boat as it would be fun to tinker with during the off-season.
I wanted to keep my routes, notes, and all the little details from those adventures in one beautiful place, just for the fun of revisiting them.
I didn’t want a social network or a clunky old app. I already have navigation covered, and I wasn’t looking for racing numbers. I wanted to start recording, put my phone away, and have a log waiting when I got back.
It needed to work reliably, even with patchy cell reception or fully offline, without draining my battery during longer passages.
And the list goes on! So every day, I keep improving and polishing Underway to make it the best boating app out there.
