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

Absolutely atrocious app, L learning

I don’t understand why anyone would use an app this bad, tell your teacher to not use this app, asked me to use boof ahh bluetoof. Made my battery drop faster than ur moms blood pressure. Puts my teacher in her silly goofy mood, that no one wants to see, trust me she starts zoomin round the classroom like Lightning McQueef from cars.

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.
