AoK — Angle of Knife
Turn your phone into a real knife-sharpening angle meter.
AoK reads the exact angle between your blade and the whetstone in real time. Set a target, hear a beep when you hit it, and keep every knife — with its angle, steel and sharpening history — in one blade log.
Four things it does
Live angle meter
Lay the phone on the blade and read the exact sharpening angle, updated in real time. No guesswork, no ruined edges.
Whetstone guide with audio
Set a target angle and get an audio beep the moment the blade hits it. Works with any tool — whetstone, guided rod, belt sharpener, bench grinder.
A blade log for every knife
Save every knife with angle, steel, photo and full sharpening history. Come back to the same edge next time — not guess.
Presets and units
Ready presets for chef's, pocket, hunting, kitchen utility, fruit & veg knives, axe, and more. Eight languages, metric or imperial.
Inside the app
Concept to both stores
Context
The MordanSoft flagship product. Existing angle-meter apps stop at the reading; the sharpening loop — target, guide, log — was left to a spreadsheet or memory.
What we did
Design, Flutter implementation, the sensor-fusion angle engine, the audio guide, the blade log, presets, eight-language localisation, and the Google Play + App Store releases.
Numbers
Live on Google Play and the App Store. First cohort of retained users on file; deeper measurement in progress.
Stack
Measure. Match. Sharpen.
AoK works offline, keeps every blade on your phone, and does not ask for an account.
