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 Science Education. Manual entry of data can be performed without a hardware purchase. For more information on Data Sharing, visit

Key Features - Data Collection
• Multi-sensor data-collection support
• Time Based, Event Based, Drop Counting, and Photogate data-collection modes
• Configurable data-collection rate and duration for time-based data collection
• Optional triggering of time-based data collection based on sensor value
• Customizable unit display on supported sensors
• Sensor calibrations
• Option to zero and reverse sensor readings
• Graph match feature for use with motion detectors
• Manual entry of data from keyboard and clipboard

Key Features - Data Analysis
• Display one, two, or three graphs simultaneously
• View data in a table or show a graph and table side-by-side
• Draw Predictions on a graph to uncover misconceptions
• Examine, interpolate/extrapolate, and select data
• Use Tangent tool to show instantaneous rates of change of the data
• Find area under a curve using the Integral tool
• Apply Statistics calculations to find mean, min, max, and standard deviation
• Perform curve fits, including linear, quadratic, natural exponent, and more
• Add calculated columns based on existing data to linearize data or investigate related concepts

Key Features - Collaboration and Sharing
• Create text annotations and add graph titles
• Export graphs and data for printing and inclusion in lab reports
• Export data in .CSV format for analysis of data in spreadsheet software such as Excel, Google Sheets, and Numbers
• Adjust font sizes for easier viewing when presenting to your class

Eye of Cthuluman ,

I don’t know where I am.

Help me. I had to download this app for my chemistry class, thought nothing of it. The app asked for my Bluetooth, which was normal because it needs to connect to a device. However, when I allowed it to have Bluetooth everything changed. I could not recognize anybody, almost like I was transported into a different universe, now living in a different life. I feel like I am slowly forgetting things, but everything here is starting to feel normal. I believe my consciousness got transferred to a different timeline which is why I am writing this review before I forget. Please avoid this all at all costs

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.

I can see again!!!!

I was minding my own business as a blind individual all my life until my AP Physics class. We were learning about something regarding forces in class and had to perform a lab to measure k constant of a spring with the help of the fantastic VERNIER. I open the app and colors begin to radiate my vision. I squinted, stunned with what was happening. I could finally see again. Vernier is the only reason I’m not Hellen Keller for the rest of my life. I believe I am finally free due to vernier, the best app ever! Lastly I would like to add that my testicular cancer cleared up like a charm because of this app. Highly recommend!
