Nailed it!!!!!!!!

I was skeptical to buy this app with no reviews.

Checked out the website and everything seemed legit.

Got it, used it, and I must say this app exceeded my expectations. Everything worked flawlessly, everything. Not a single issue sending the CSV files around and the user interface is so friendly I couldn’t believe it. I didn’t even need the instructions cause everything worked just like they said it would.

I am using this app in a NASA, STEM research project and the amount of time this app is saving me is priceless. To manually do these readings....don’t even want to think about it.

Thank you guys so much
