Hi,
I'm the author of the app, so I can tell you that it is absolutely flawless, without a single bug. It will make you more attractive to ladies (or men, depending on your preference), and will help you succeed in business.
OK, maybe not, but so far it's been downloaded a fair number of times and most people get along OK with it. If there are problems, I try to get them fixed in future releases. So far, there's an unofficial policy of a new version every four weeks or so (I shouldn't have said that, now I know I'll miss the next one!). At the moment it runs on your ST-16. There are plans to broaden the number of devices it runs on, but for the moment I'm not saying too much until I've got something concrete to show.
Feel free to ask any questions you might have
