ARAMIS App vs Thread Gauge
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
ARAMIS App
This utility app assists users in planning and executing precise motion and deformation analyses with a ZEISS ARAMIS system. It calculates necessary sensor settings, including distances, and provides essential data for optimal setup. Users can also view compatible reference points and touch probes.
- Plan measuring tasks
- Reliable task execution
- Compute sensor settings
- Optimize system setup
- View reference points
- View touch probes

ZEISS's free ARAMIS App is the perfect app for a versatile measuring system, letting you plan measuring tasks quickly and reliably and giving you more time for those high-precision motion and deformation analyses with your ARAMIS system. The app computes the required sensor settings, such as measuring and camera distances, and provides all the data you need for an optimum setup. You can also see which reference points and touch probes you can use.
Thread Gauge
This app transforms your iPhone into a precise thread measurement tool. Simply photograph a screw next to a reference card to accurately determine its pitch and diameter, identifying the closest standard in both metric and imperial units.
- Measures metric and imperial threads
- Identifies closest standard match
- Uses reference card for scale
- On-screen guidance for photography
- Offline processing, no data tracking

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. Questions or feedback?

Verdict
The clearest difference is update cadence: Thread Gauge at every 6 days against ARAMIS App's every 17 months. ARAMIS App's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (13.4 vs 17.6). On price, rating, ratings volume and ads there is nothing between them.
