## Thread Gauge Description
Thread Gauge turns your iPhone into a precision thread gauge. Photograph a screw next to a common reference card, and it measures the thread's pitch and diameter, then identifies the closest matching standard — in both metric and imperial.

No calipers, no thread gauge set, no guesswork. Just a photo.

HOW IT WORKS

Lay the screw on a plain background, parallel to a reference card: a credit or ID card (85.6 mm) or a full-size SD card. Use the light intensity slider to apply enough light to minimize shadows around the screw. Use the bubble level to find the best lighting angle — a green dot inside the circle is ideal. Move your phone closer or farther to get the sharpest focus; the sharper the image, the more precise your measurement. Snap a photo or pick one from your library, choose which card you used, and tap Measure. ThreadGauge uses the card as a known scale to compute the real-world thread pitch and major diameter.

It all runs on your device — no server, no account, no tracking. Nothing you photograph ever leaves your iPhone.

WHAT IT IDENTIFIES
- Metric coarse and fine (M-series)
- Imperial UNC and UNF
- Thread pitch (mm and TPI) and major diameter
- The closest standard match, with a confidence indicator

When two standards are nearly identical — for example, a #10-32 and M5×0.8 — Thread Gauge flags the ambiguity so you can confirm with a physical gauge instead of trusting a borderline read.

FEATURES
- Metric and imperial in one tool
- Tap to look up any identified size online
- On-screen guidance for lighting, angle, and framing
- Made for makers, machinists, mechanics, and anyone holding a mystery bolt

PRICING
Your first 3 measurements are free. One simple in-app purchase unlocks unlimited measurements — no subscription, ever.

PRIVACY
Thread Gauge collects no personal data, and your photos stay on your device.
