There are two primary data collection applications published by Vernier: Logger Pro and Graphical Analysis Pro. Logger Pro, a mature and powerful data collection and analysis application, runs on macOS and Windows only. Graphical Analysis Pro is a newer data collection and analysis application that runs on macOS and Windows, and in addition runs on iOS/iPadOS, Android, and ChromeOS.

Logger Pro is available with a perpetual site license. Graphical Analysis Pro is available by subscription. There is a free version, called Graphical Analysis, with fewer features available as well.

Users of iOS/iPadOS, Android, and ChromeOS must use Graphical Analysis Pro or Graphical Analysis for general data collection; Logger Pro is not an option.

What is the difference in student experience in using Logger Pro and Graphical Analysis Pro? Here are some things to consider.

Computers Running macOS or Windows

Vernier has been developing software for Mac and Windows for decades, and Logger Pro, our data-collection software for Mac and Windows, is very powerful. We offer written curricula for collecting data using Logger Pro.

The following hardware only works with Logger Pro on a computer:

  • LabPro interface
  • Ohaus balances
  • Watts Up Pro
  • Wireless Dynamics Sensor System
  • Respiration Monitor Belt
  • Polarimeter (Chemical)
  • Digital Control Unit
  • Vernier Structures and Material Tester – linear displacement sensor (Force sensor is supported)

Go Wireless sensors don’t work with either Logger Pro or Graphical Analysis on a computer:
Note that the Go Wireless line is distinct from the newer Go Direct line. Go Wireless sensors can be used with LabQuest 2 or LabQuest 3 as a standalone device, or the app Graphical Analysis GW on a mobile device.

  • Go Wireless Temp
  • Go Wireless pH
  • Go Wireless Electrode Amplifier

(Note: Go Wireless Heart Rate and Go Wireless Exercise Heart Rate are supported by Graphical Analysis, but not Logger Pro.)

Some sensors made before ~2003 do not automatically identify themselves (Auto-ID) when connected to an interface and require Logger Pro

Certain advanced Data Collection and Analysis Features require the use of Logger Pro on a computer:

  • Gel Analysis
  • Mapping data (export to Google Maps or ArcGIS)
  • Error Bars (coming later to Graphical Analysis Pro)
  • Complete experiment files (also known as template files) for the experiments in our lab books
  • Obtain the highest performance from interfaces
  • Work with very large data sets

Some books are written using Logger Pro software but do not have experiments written for Graphical Analysis (Chromebooks):

Chromebooks, iOS, and Android

Chromebooks are inexpensive and very easy for IT to support. Tablets offer great portability and ease of use. As a result these platforms are increasingly common.


If full-featured data collection and analysis from a wide spectrum of devices is your goal, traditional computers are the most versatile choice for now. You can use either Logger Pro or Graphical Analysis Pro, or even both (just not at the same time).

If basic data collection with the most common sensors is what you need, the Chromebook and mobile platforms are good and inexpensive options.

What features are available in Graphical Analysis Pro that are not available in the free version?
