I could use a calculator like this, it looks to be pretty cool. There isn't any feedback or ratings about it yet. Is anyone using it yet? How do ya like it?
How long does the promo code last? Is it only trial version or time frame with the promo code? It's not an expensive app at only $0.99 to purchase, but I guess saving a buck is saving a buck.
But still, any feedback? Anyone?
Once you obtained an app by redeeming a promo code, you'll own the app forever.
I've just PMed you a promo code so you can get the app for free.
