I plan to keep a free tier for small groups, as I am trying to make life easier for pilots. But I won't hide that it will be a subscription model (like goboko and others) for larger groups, renters, flight schools, etc. While my time is arguably free, the infrastructure hosting the system isn't, and I'm hoping that the paid customers can keep it free for small groups forever. If that counts you out, that's totally reasonable, and if that's the consensus, I'm also happy to take the post down.
