Yack is still in beta, and under active development. We're working hard to make it the best it can be, and we're excited to share it with you.
As far as how much it will cost, we're still figuring that out. We want to make sure that Yack is affordable for everyone, and we're working on a pricing model that will make that possible. We'll be sure to let you know as soon as we have more information.
What we are certain of is, it would not be a subscription. We don't like subscriptions, and we don't want to force you to pay for something each month in hopes of upgrades and improvements.
Pricing will be one-time, and you'll get all future updates for free.
