Crash on larger messages
The reason you would use this program is for longer emails, usually more important communication that you are copying to several recipients. You want an email of this importance to be spell checked. One problem here. The program crashes everytime you try to check even a medium size email. If the program only works on quick informal communication, whats the point? On small informal emails a writer usually abbrieviates heavily and spelling is not critical. If you want 5 stars make longer messages work in your program. This is not a memory issue with iphone as I am using a 32G 3G S. This is a problem with your software.
