What’s the standard method of geometric dimensioning and tolerancing? Which symbols represent which tolerances? Need quick answers to your questions? You can use our apps and e-books to look up metrology information anytime. You’d be able to find out, in next to no time, things like what symbols are used to convey tolerance for cylindricity or concentricity.


These days, almost everyone has apps on their phone, and uses them daily. Apps make it easier for us to buy train tickets or catch up on the latest headlines. What’s great about them? You can use them anytime and anywhere. Our ZEISS apps provide you with metrology information whenever you need it.

GD&T App

Form deviations, tolerance boxes, datum features – when we get lost in the jargon jungle, we normally look for quick solutions. The ZEISS Form and Location app is here to help. It’s your mobile dictionary for form and location tolerances as per DIN EN ISO 1101. The app contains many great videos – here’s a preview:

Properties of a part

Classification of geometry tolerances

Other apps

As well as improving your knowledge of form and location tolerancing on the go, we also offer apps that teach you about the basics of coordinate measuring technology, industrial computed tomography and gear measurement.

We Produce Quality

An introduction to coordinate measuring technology

The app provides an introduction to coordinate measuring technology and offers practical tips for day-to-day work with a measuring machine. Key topics include correctly aligning workpieces, features and characteristics, as well as the influences on the measurement result.

Gear Metrology

Gear measurement - the basics at a glance

This app offers a look at industrial gear metrology. It helps assess measurements and explains typical parameters such as tooth traces, circular run-out radials and tooth thickness.


The most common surface parameters

When it comes to the surface of workpieces, a large number of surface parameters are required in design and manufacture. The roughness app from ZEISS provides information on the most common surface parameters.

Cookbook App

Measuring strategies for tactile Coordinate Metrology

The Cookbook app gives you the most common measurement strategies, enabling coordinate measuring machine operators to design the measuring run and perform and evaluate the measurement.

CT Basics

For a basic understanding of industrial computed tomography

The app is ideal for acquiring basic knowledge of industrial computed tomography. You will learn about topics such as using X-ray radiation, the measuring process and subsequent analysis. A glossary explains specialist terms like beam hardening, binning and defocusing.


Dimensioning and tolerancing according to ISO 1101

This app describes a large range of definitions of geometric dimensioning and tolerancing and supports engineers and employees as a multimedia reference book.

In the Pro version, you have access to additional videos and content.

ZEISS eBooks

Do you sometimes need additional information? Then look no further than our e-books. They’ll give you an in-depth look at the world of metrology. Be it on your smartphone or tablet, the e-book provides you with all the essential information without delay.

Measurement Strategies

in contact coordinate metrology

Increase the comparability of your measurements: the ZEISS ACADEMY METROLOGY e-book gives you ideas on how to define and document measurement strategies. These include clamping, reference definition, probing, evaluation and presentation of results.

Standard-compliant tolerancing, form and location tolerancing

Possibilities of the new GPS standards

The e-book looks at the different aspects of dimensioning and tolerancing workpieces to ensure functionality, production stability and, most importantly, compliance with standards. An overview of the international GPS standards (incl. the differences to ASME standardization) is also provided. 14 rules on test-compliant tolerancing are then derived and explained.
