Works, but don't expect support
Works well as a basic unit calculator, but switching between this and the Storm 8 game takes longer than just using a regular calculator. The program is supposed to come with a companion program on the net - so you can make entries on the computer without having to keep turning the game on and off to toggle back to the app. When you buy the app, they're supposed to send you logon info to your email. Don't believe it! I bought it over a week ago and they sent nothing. I tried requesting/changing my password online - nothing. Support is non-existent and the online portion of what you're supposed to have bought does not exist. Until they fix this, I would recommend not buying this app.
