Being built: 494 in development. None of these can be installed yet; each listing says what it will do, what it will not, and takes waitlist names.
The same list, cut by the kind of practice each app is written for. 369 more are for every kind of practice and appear only above.
The surface is drawn and the platform under it is ready; the app itself is not built. Each listing says how far it has got.
Name, number and the practice you run. Say which of these you are waiting for; the lead board counts every request, and the most-asked move up.
