TVM requires payment

The one reason you want an HP 12C is to do TVM calculations this app won’t do them unless you pay for the upgrade.
TRThe Geek Pirate Roberts

Misleading

Forget this app! They make you believe it’s free but as soon you want to perform a calculation, it asks you to upgrade.
Just by the real app from HP. No gimmicks there!
