Tell us what to build next. NEW Feedback board. See what other owners are asking for, vote on the ideas that matter to you and post your own. Find it under More > Feedback. Per-engine tracking. Twin engines do not wear evenly, so each one now carries its own hours, its own nickname and its own service schedule. Adding an engine mid-life? Anchor it at its real hours instead of starting from zero.

Faster ways to get in. You can now sign in with Apple or Google instead of typing a password. Your email and password still work exactly like before, and everything in your account stays right where you left it.

Bug fixes

The app is now called The Wrench. Same account, same data, new name.

Fixed bugs

Marine Keeper now works for more than just boats. We've rebuilt the app so the same simple tools fit whatever you own, starting with bikes. You still get a clear maintenance schedule, plain-language guides that explain how things work, and savings tools that help you plan for the next repair before the bill arrives.
