Works well, but is missing some essentials.

My classes have been using this app to do labs on their Ipads with our LabQuests. However, some of the features seem clunky when creating graphs by manually inputting data. In addition and most importantly there needs to be an integral function as I teach physics. There are a lot of times where this is essential. It can be done on the LabQuest but does not transfer to this app. It doesnt make sense to not have this function. It would be great to see this added and would make this a 5-star app.


It works well!

I used my IPhone 6s to download and install the software. The Bluetooth connection needed to via software, not phone Bluetooth connection. After did some modifications on x & y axis through graph options at lower left corner of software. It works well!! Very convenient for my gas law experiment.

Pretty Useless If You Don’t Know The App

The user interface is a maze to understand. There’s tons of stuff that isn’t explained and you’re bound to get frustrated trying to do something that you’d think is simple. I’m obligated to use this app for my Physics class so I’m sure that this app will do a great job at messing up my grade.
