How we build

Useful tools for real work.

We make focused tools that help you repair, document, and keep track of the work that matters.

Repair and reuse first

We build for the practical work of fixing, restoring, and making good things last.

Private by default

Where we can, we keep your information on your device and avoid adding an account just to get you started.

Clear records, fewer loose ends

Photos, notes, and mix details are more useful when they are easy to find and ready for the next job.

Made for the bench, site, and home

Our apps are designed to be useful in the middle of real work: simple enough to reach for, capable enough to keep.

Follow along

Practical repairs, app updates, and useful methods.

Follow Blue Leaf Kobo for the work behind the tools and ideas you can put to use.
