Ratings and reviews

Perfect for when you can't talk (laryngitis) or when other people can't hear (noisy environments, hearing impairments). Sideways-swipes allow quick access to different areas of the app. It stores messages (you can delete them) which I like because I can reuse messages later without having to retype or re-select style. I also like that you can't accidently swipe *between* stored messages, which prevents clumsily showing the wrong message. Could use more styles, but the app's simplicity is good.

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).

It does what it says it will do. I like how it saves previous entries for quick access by holding down the icon for a list on the home screen. I use it to alert drivers (so many forget to turn on their headlights so I have a message saved just for that.)
