It is currently maintained by one excellent developer, is featured by the Apple App Store for design... what's the downside?
They've worked really hard on making sure their official app is an actual piece of garbage. I am truly impressed at the amount of work it takes to make something that is that bad. People being paid for the existence of that app make me feel good in that no matter how bad I can get, no matter how senile and incompetent I'll become, there'll be a job for me somewhere. Paid absurdly well, too.
