Wakelog

Logbook for every trip you cast off.

Every feature, from the first launch.

No account, no login, no cloud. Everything runs on your device and works fully offline — nothing in this post is hidden behind a wall.

What Wakelog does

Wakelog is the modern offline ship's log for the 15.4 million US recreational boats. Sailors, powerboaters, and cruisers keep a logbook because they have to and because insurance and charter handovers ask for one. The existing apps are sub-1K-install niche tools with dated UIs, freemium gates after three trips, or feature-light track recorders.

What ships in v1:

— Start a trip. Tap depart. Wakelog auto-stamps the entry: position (CoreLocation), heading (CoreMotion), heel angle if sailing (accelerometer), local time. Engine-hour counter starts. — Hourly auto-entries. Underway, the app logs an entry every hour with position, heading, heel, and a tap-to-pick Beaufort sea state. — Crew + sails picker. Tap which crew is aboard, which sail combo is up. The list is yours to edit. — Incident button. Reef in. Tack. Crew overboard drill. Engine start. Custom tags too. — Engine hours. Rolling counter across all trips. Tap to record an oil-change milestone. — PDF logbook export. One tap, a clean PDF of your whole season, ready for insurance, charter handover, or your own shelf. — Bundled tide constants. NOAA harmonics for major US coastal stations bundled — predict next high/low at your location, offline. — No account, no analytics, no third-party SDKs, no subscription. Free. Optional iCloud sync via your own Apple ID (Apple-native, never our server).

For the 2M+ US sailors and the millions of powerboaters who have been waiting for a logbook app worth using.

Export PDF — Per-season PDF logbook via share sheet

Why we built it

Recreational sailors keep paper logbooks because every digital option is sub-1K-install indie or aging — Skipper paywalls after 3 trips, SailTies is a track recorder, Logbook Suite has a 2012 UI. None auto-stamp position + heel + sea state.

What makes it different

Wakelog is the only iOS ship's log that auto-stamps an entry every hour underway using CoreLocation + CoreMotion (heading, heel angle), bundles NOAA tide harmonics for US stations, and exports a single insurance/charter-grade PDF — Skipper paywalls after 3 free trips, SailTies is a GPS tracker without a structured log…
