Disc Vault
A web app for cataloguing discs and tracking which bag each one is in, with a public lost-and-found library alongside it.
Apps & Software
Disc RPM
A free bag builder organised around spinnable photos of the actual discs rather than mold names, with flight charts and community bag sharing.
What to know
The premise is that a bag is easier to assemble by sight than by name, so a disc is added with photographs of the real thing that can be spun to show the stamp and any dye work from every angle. Discs are then grouped into bags and charted by speed and stability, and a bag can be shared with a club or the wider site.
More detail
Gaps work sideways from most tools here: rather than naming a hole in the lineup and stopping, it shows the discs that players with similar bags actually carry in that slot. It runs in a browser and as an Android wrapper of the same web app, is free with no paid tier, and is funded by donations. Its author describes it as a learning project finished during a recovery from knee surgery.
