Description

From the listing uploaded by “appupdater”.

Make potency testing easier! The tCheck Android App allows you to calculate your recipe dose, log your CBV test and review previous results. Having your tests on your phone will help declutter and organize your herbal testing process. Being consistent is more than knowing your infusion strength, but also keeping track of what works best for you.
