What can I test with it?

Oils, butter, and other infused bases — the everyday stuff home makers actually cook with.

How accurate is it really?

Results run within about 3% of lab equipment, so you can trust the number you get.

Do I need any special skills?

No. If you can use a phone app, you can use tCheck — results and guidance are all built in.
