Spool Log - 3D Print Manager

Know exactly how much filament you have left. Log every print, track every spool, never run out mid-job again.

Spool Log is the simplest way to manage your 3D printing filament. Add spools, log prints, and always know how much material is left - down to the gram.

Always Know What's Left Each spool shows its remaining weight live, updated every time you log a print. A colour-coded progress ring makes low filament obvious at a glance.

Log Prints in Seconds Enter the grams used on a custom keypad, tag a project name, set print time, and attach a photo. The app deducts the usage and shows you what's left instantly.

Full Print History Every print you log is stored with project name, date, grams used, duration, and an optional photo. Filter by month or view the complete history with Pro.
