Graphical Analysis™ is a tool for science students to collect, graph, and analyze data from Vernier sensors.

Sensor data-collection support:
• Vernier Go Direct® sensors - with Bluetooth® wireless technology
• Vernier Go Wireless® Heart Rate and Go Wireless Exercise Heart Rate monitors
• Vernier LabQuest® sensors used with a LabQuest Stream interface

Additional experiment options:
• Data Sharing via Wi-Fi connection to LabQuest 2 or Logger Pro® 3
• Manual Entry

Note: Sensor data collection and Data Sharing require the purchase of hardware from Vernier Software & Technology. Manual entry of data can be performed without a hardware purchase. For more information on Data Sharing, visit

This is app should be banned

Ever since my son’s chemistry teacher made him download this app, he has not been his normal self. He has been eating soup with a fork and using a spoon feed cheetos to our pet hamster, who is now dead, probably a direct result of vernier graphical analysis. Also, at exactly 3:42 AM every night, my son wakes up and screams “help me daddy, vernier graphical analysis is eating at my soul.” My wife is quite annoyed by this and has sent vernier hq several emails but of course no response. She is thisclose to doing violence towards them. My son now has no friends and sits at the lunch table alone with his vernier graphical analysis. Please destroy this app it has no business existing.

Why so many 1 Stars...?

I don’t understand why this app is so lowly rated works just like it should.
Update: Completing my second physics lab with this app now and I still enjoy it. So far it has deleted one of my graphs when I closed it but it’s only done this once. I can plot multiple columns from multiple data sets in one graph which is great but you can’t pick and chose which columns you want plotted from each data set. So if you want to plot velocity from data set 1, tension from data set 2 and log (tension * velocity) from data set 3 you can’t. You can however do this in the PC version of Graphical Analysis but again a good app just understandably missing some features.

Excellent app for use with iPad and Vernier Go Wireless probes/sensors

If you are familiar with the use of Vernier probes and sensors (temp, pH, drop counter, pressure, etc.) along with the LabQuest devices, you will quickly adjust to this app.

Note: You do need Go Direct (wireless bluetooth) probes and sensors (or use LabQuest in data share mode via WiFi).

We have used this with many students, and the app works quite well. Still a few small bugs/feature refinement needed, however, virtually anything you could do with LabQuest you can do with this app.
