Thiis app does its job very well. You can enter several sentences at once and then hit translate. If it is not perfect edit it then hit speak! You will be amazed. Polish voice sounds natural and is very nice. You will not be able to tell that it is synthetised. You can save a list of your translations for future uses. This can be great tool for travel or to teach your girlfriend/boyfriend Polish or your visitors from Poland to learn English. I cant wait for copy and paste comming with iphone OS 3.0 this summer. It will make this app even more usefull.
