Purchased SpaceTime for my iPhone a while ago. When I bought an iPad I realized the app was split to support the higher res screen. I paid AGAIN for it as the iPhone version looked horrid on it. That's $40 already. Now, they try to scam people by renaming the app so they don't have to honor updates! Outrageous.
Overall this is a great app, it handles symbolic math very well. The one feature that is really missing is the ability to insert previous results into the current line (this would ideally work by just tapping the number you want to insert). It does have the ans function, but that is not as useful.
I bought the original SpaceTime when it first came out (for something like $20). I would love to give this a 5-star rating but do believe the ratings should consist of service as well as the app. Because of your double-dipping current customers (no it isn't Apple's fault)... I have to give the service for this app a -5 star rating. So 5 stars for the app plus a negative 5 stars for your ridiculous pricing and upgrade policy makes that a zero star rating (but unfortunately I'm forced to choose at least one star so consider yourselves lucky). I definitely won't be buying the new one because of your policy and will continue to use SpaceTime ONLY until a suitable competitor comes along and then it will be buh bye if you haven't taken your current userbase back into account by then.

At its present price of $3, one should not hesitate: This app is marvellous. [I understand anyway the previous customers' disappointment, who had paid $20 but do not have access to the new version 5, renamed MathStudio, unless they buy it again.] Admittedly, it usually suffices to visit the free WolframAlpha website with Safari, but SpaceTime does not need any Internet connection, it is programmable, and its tactile interface to rotate 3D surfaces is outstanding. This interactivity is also what goes beyond the free but excellent M#Math Mini. [On the other hand, my first tests show me that SpaceTime is numerically less accurate than M#Math Mini.] To conclude, if one does not have nearby a desktop or laptop computer with Mathematica installed, it is obvious that SpaceTime can be extremely useful! I do not regret my $3. 8-)
The developer stopped supporting this rather expensive App and wants customers to pay AGAIN for a marginal upgrade under a different name. No thank you.
I can't believe apple is even accepting your apps. Way to support your early customers. Had it not been for us you wouldn't have had the money to develop MATHSTUDIO. I'll never buy another app from you guys again.
