Remember · reusable setup

Save the fit that already works.

Keep all ten widths, curve observations, and finger-specific notes together. Useful when one index needs a shorter laptop tip, a thumb is between sizes, or a reusable set gets mixed up after removal.

Your profile stays in this browser when you choose Save. Widths remain in millimeters; this tool does not convert them to universal 0–9 sizes.

This is a fit notebook, not a medical record. If a nail is painful, injured, irritated, swollen, or otherwise concerning, stop cosmetic troubleshooting rather than saving a “tighter” fit.
