Very poor
This app is full of errors. This need a lot of work. I suspect that no one that speaks English is editing this program. Virtually unusable.
Dr
A mix of basic stuff and formulae of dubious origin. Poor documentation for basis.
Dissappointed
This is not worth $5. They published the app before completing all the formulas. This should be a free app until it has the formulations installed.
Rubbish app
This is a rubbish app. You'll be wasting your money. Rubbish app.
Of limited use
Imperial units only, and no information on formulae used.
