Being able to direct and broadcast messages to anyone within viewing distance, silently, is a handy tool for all kinds of scenarios. I been needing this for a long time. Can also be used to tell a driver his tire is flat instead of headlights and honking on the interstate. Or yes perhaps 'save a life, use a blinker'.. Seems like a skilled developer, app is packed with features and customizations for messages, yet is one touch 'play' to play a message immediately, with default settings. All this and only 5.8mbs? A rare app that has real world usefulness.

Last night I used this app to alert police to where their suspect had gone. I was standing in a parking lot about 50 feet away and about 2 stories above ground so shouting wasn't an option. Quickly typed my message and the authorities reacted. With my help they were able to catch the perp. Theres plenty of other situations where this would be very helpful. Definitely on my home screen.

The fonts for other languages besides English (such as Chinese and Japanese that was marketed in the pictures) cannot be bolded. It just ends up looking awkward and thin when set to LED. Not just that but the words are not centered to the middle as shown in the pictures. The words lay slightly closer to the top than bottom. Personally not a big problem, but I think it’s a waste of blank space, when that extra space could be used to make the words appear larger on screen.

Great for scrolling the lyrics to songs sung to residents. I record accompaniments on the iPhone record app; start the music Blutoothed to portable Bose speaker. The introduction gives me ample time to bring up your app where the lyrics are prepaced to the music. Works like a charm without the need to carry, set up and tear down a bunch of equipment each time!
