## What is Knife Sharpening Log & Timer?

A sharpening session is only repeatable if you wrote it down. This app records the stones you pulled, the angle you held, the minutes you spent on each grit, and how the finished edge actually cut — so the next time that same blade comes off the board, you already know the sequence that worked.

BUILD YOUR BLADE LIBRARY
Add every blade you maintain: chef's knife, paring, boning, pocket folder, chisel, plane iron. Each one stores its steel type, its bevel angle in degrees, your own working notes, and a color tag so you can spot it at a glance in the list. Sort or search the library, and see at a glance which blades were done recently and which have gone untouched.

RUN A TIMED SESSION
Pick a blade, hit start, and a running timer takes over. As you move up through the progression, add a grit phase for each stone you use and the minutes you spent on it. The session builds itself into an ordered record of the progression rather than something you try to remember afterward.

RATE THE EDGE YOU GOT
Finish a session with a one-to-five rating and a note on how it went — burr came up fast, needed longer on the 1000, the 12000 was overkill. Those ratings are what turn a pile of sessions into a usable pattern.

STONE INVENTORY
Keep a record of the stones on your bench: grit number, family (Japanese water, diamond, oil, ceramic), and soak time for the ones that need it. A grit-progression strip lays your inventory out coarse to fine so gaps in the jump are obvious. A starter set of common grits is already loaded; add, edit, or remove to match the stones you actually own.

PER-BLADE NUMBERS
Open any blade to see how many sessions it has had, its average edge rating, total bench minutes, and the average number of days between sharpenings. Library-wide totals and a session streak live in the history tab.

MAINTENANCE REMINDERS
Set a cadence per blade — 14 days for the workhorse, 90 for the one that rarely comes out. A local notification nudges you before the edge wanders, and it reschedules itself from your most recent session.

EVERYTHING STAYS ON THE DEVICE
No account to create, no sign-in, no sync. Your blades, stones, and session history are stored locally on your iPhone.

Built for kitchen cooks, hunters, woodworkers, and anyone who would rather keep a real maintenance record than guess.

Knife Sharpening Log & Timer requires a Pro unlock to log a sharpening. Pro opens the whole bench record: an unlimited blade library with steel type, bevel angle, notes and color tags, timed sessions with a grit phase for every stone you pull, edge ratings and session notes, the stone inventory with its grit-progression strip, per-blade numbers for sessions, average edge rating, bench minutes and days between sharpenings, the full session history and streak, and per-blade maintenance reminders. Plans: a weekly subscription, a yearly subscription, or a one-time lifetime purchase.

Payment is charged to your Apple ID account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours prior to the end of the current period. You can manage your subscription and turn off auto-renewal in your Account Settings after purchase.
