I like that it allows me to make sure my text messages are within the limit of 160 characters for all carriers, even if they have different character limits per carrier! It's also easy enough to use without having to spend time learning how to do so. The price is a little high compared to other apps in this category (like TextExpander), but I think overall the app does what it promises very well. Sometimes you get an error when trying to send a message with too many characters or exceeding your texting plan's limit. That can be frustrating since there isn't much help from the developer in resolving those issues. If you're looking for something that will let you know early whether a message could exceed your texting plan's length restrictions before sending, then this should definitely be considered. Knowing ahead of time helps prevent costly mistakes.
