Keeping your boat shipshape!
Features
Everything AftLog does for your boat — logging, planning, checklists, and safety, built to work even with zero signal.
Maintenance Logging
Track every service, part, and interval for each boat. AftLog learns your engine's real hours and tells you what's due — spark plugs at 200 hours, impellers on schedule, lower-unit oil when it's time.
- Real engine-hour learning
- Smart interval tracking
- Due-soon notifications
- Multi-boat support
Fuel & Range Intelligence
Log fills and trips and AftLog learns your real km/L and km/hr, then shows how far and how long you can run before the tank is low.
- Real fuel efficiency learning
- Range prediction
- Time-to-empty estimates
- Trip history
Checklists
Launch, retrieve, towing, winterization, spring prep, and used-boat inspection — step-by-step checklists that teach as you go. Beginner Mode explains each item instead of just checking it.
