If you have written a text message that is no longer relevant when it is to be sent, that's not a problem. The software will alert you when a message is about to be sent, so you can delete it or update it as appropriate.
This app allows messages to be scheduled for a one year time in the future. You also get a Web console, where you can manage your messages using a browser interface.
Web console have more features than iphone version like social media share(Facebook & Twitter) and Analytics allow you to check how many people like or comment on your scheduled post.
One caveat, We've just started using this app, so there may or may not be kinks that need to be worked out. But I think you'll agree that it is a great idea, especially for time-challenged small-business owners who need to act on great ideas on the spur of the moment, even if the moment is in the future.
