Ratings and reviews

I tried a bunch of apps with similar features, and this one has be best UI, but lacks some features (swiping between saved messages, choice of portrait or landscape), and while you can pay to get more than just black and white, the paid version apparently only has a bunch of (weird) pre-feb designs, not the ability to just, say, choose a red background and yellow text. I ended up choosing a different app that has more free features, but a less user-friendly UI. Would still recommend this one for anyone who just want the simplest, clearest UI and doesn't need anything more than black-and-white (which I'm fine with).

In the latest update, they removed the rotate button. getting forced into portrait mode is really obnoxious when we are trying to have text be large enough to read with words that are more than four letters long.

Limited functionality! Free versions do far more including scrolling text on plain backgrounds, exporting GIFs and also more user friendly. The paid upgrade to offer all themes is definitely not worth the money. I incorrectly believed the themes would allow me to have scrolling text on plain background but was dissappointed by the limited options. Have deleted the app and gone for a free app called LED Scroller which gets 5* and I'm very pleased!
