One thing I really do not like is you can’t change it from vertical to horizontal, as I can tell. I have a keyboard attached to my iPad and my keyboard just stands in the air; don’t like that at all. It’s a little more difficult to use than the one I previously used, which is not satisfactory however it does have a feature that I do like that the other one I had did not. I will check back later after I’ve used it a little longer. That is my honest opinion thus far. At this point, I am neutral on a recommendation. **Developer response:** Hi Justaboutit, Thank you so much for taking the time to leave a review and for your honest feedback! We really appreciate you letting us know about your experience with "Lion Prime Numbers." We completely understand your frustration with the lack of landscape mode, especially when using a keyboard attached to your iPad. We’re happy to let you know that version 1.3.0 now includes full support for landscape orientation! This should resolve the issue you mentioned and allow you to comfortably use the app with your keyboard. We value your opinion and are always striving to improve "Lion Prime Numbers." We're glad you've found at least one feature you like. We're confident that the landscape mode addition will make the app even better for you.
