Keeping your boat shipshape!
Boat owner's logbookAftLog is the maintenance logbook your boat deserves: engine hours, fuel, service history, and seasonal checklists — with reminders that actually fire, and AI that explains what that noise was.
New to boating? AftLog teaches you your boat, checks you're ready before you launch, and tells you what to do when something's wrong.
One-time payment. No subscription. No ads. Your data stays on your device and syncs when you want.
Rows you forget to add, columns that drift, and a file that lives on the laptop, not at the dock. Winterization checklists are a paper printout somewhere.
Fishing-trip loggers and GPS apps track where you went, not whether the impeller was replaced or when the lower-unit oil is due.
Most are hollow list databases, die offline, or bury your own logs behind ad screens. That's why nobody's heard of them.
Most boating apps assume you've been doing this for years. AftLog doesn't. If your boat is new to you, it teaches the essentials, keeps you safe at the ramp, and only ever shows the one thing you should do next.
Is your boat ready? One glance gives you green, yellow, or red — and the single next thing to do. No maintenance expertise required.
Engine won't start? Taking on water? One tap gets calm, step-by-step instructions — and your exact GPS position ready to share with help.
Short guided cards teach the essentials: bilge pump, battery, oil, trim, navigation lights, shallow water. "Got it" moves you on — "show me later" saves it.
Drain plug, battery, fuel, life jackets, kill switch — every item with a picture of what to look for, so the mistakes everyone makes once, you don't make.
Backing up, ramp etiquette, avoiding the jackknife, getting on and off the trailer — guided steps for the most stressful 20 minutes in boating.
A simplified dashboard: one next task, your fuel range, and a daily tip. When you're ready for everything, switch to full mode — nothing is locked away.
Offline-first, like you are at the lake. Every feature below works with zero signal, and syncs when you're back on the dock.
One tap to log hours at the dock. Auto-estimates hours from trips if you forget, so the log stays honest.
"Lower-unit oil due in 40 hours." "Winterize in 3 weeks." Based on your engine, your hours, and your region's season.
Commissioning in spring, winterization in fall — prebuilt checklists for your engine type, with photos and receipts attached.
"Outboard won't idle after winter storage." Describes symptoms, gets likely causes ranked by what your log shows, in plain language.
Offline-first on device. Sync across phone and tablet when you choose. Export the whole log to PDF or CSV — yours forever.
"Why won't it start?" Pick your engine and the symptom — get ranked causes, fix steps, and when to call a mechanic.
AftLog starts as an offline logbook on your phone. When you're ready, you export a bundle and send it to the Web Portal — a full analytics dashboard for your trips, fuel, maintenance, and boat health.
Every log entry you make offline — hours, fuel, services, checklists — becomes real analytics when you choose to sync. No accounts, no always-on cloud, just:
The Web Portal is included in your AftLog Pro license. You can ignore it and stay fully offline — or use it when you want deeper insight into how you actually use your boat.
Runs on your own machine today, and will be available as a secure cloud service later. The same data model as the app, just with bigger charts.
AftLog is built for the 11 months a year your boat is more project than boat. The app keeps you honest at the dock; the portal shows you the bigger picture when you're back home.
Boat Health Score, next task, and fuel range — the things you need before you launch.
Launch, spring prep, winterization and more — with guided steps and safety checks.
Total trips, distance, hours, fuel, and cost — plus efficiency, highlights, and multi-year trends.
Per-boat cards with hours, fuel, compliance, and a 0–100 health index.
AftLog doesn't force you into an account or a cloud. You use it offline like a proper logbook — and when you want analytics, you send a bundle to the Web Portal.
Engine hours, fuel, services, checklists, and symptoms — all on your phone, even with no signal at the lake. Reminders fire locally; nothing depends on a server.
When you want a deeper view, you export a single bundle file from the app. It contains your boats, trips, services, intervals, and checklists — nothing is sent on its own.
Import the bundle into the AftLog Web Portal to see Year-in-Review, trip analytics, maintenance dashboards, and boat health — all computed from your own log.
Launch price is $29. Waitlist members lock it in — it may rise after.
AftLog has a free tier for one boat, and a $29 one-time Pro license that covers everything: the full app and the Web Portal. No monthly fee, no ads, no upsell screens.
One-time, not rented. Your license covers the app and the portal — the portal just runs on your own machine today, and becomes a secure cloud service later.
At launch, the $29 Pro license covers both the offline app and the Web Portal analytics suite. Waitlist members lock in this price, even if it rises later.
No subscription. No ads. No data mining. Just a logbook and its analytics, built for the kind of person who keeps their boat longer than their phone.

If you're the kind of person who keeps a notebook in the glove box, this is for you. AftLog is built to replace that notebook — without losing the parts that make it yours.
Yes. The app is offline-first: logging, checklists, and reminders all work without signal. AI diagnostics have an offline fallback when you're out of range. Sync and export happen when you choose.

Yes. AftLog supports common outboard and inboard configurations, with service reminders and checklists tailored to your engine type.
Your log lives on your device. You can export it to CSV or PDF anytime. The Web Portal computes analytics from your bundle; we don't sell or mine your data.
AftLog is built for boat owners in Canada and the US first, with seasons and reminders tuned to those regions. Other regions may work, but aren't optimized yet.
