Croissant starts at $2.99 per month, or you can pay $19.99 per year or a one-time fee of $59.99. That's probably too much for casual posters, granted—McCarthy says the intended audience is really small business owners and creators "who use social media professionally, but is not their full time job."

I can see the appeal of the annual cost—even the one-time fee. If you post at least once a week, that’s 156 posts across platforms per year. Add Instagram into the mix and now you’re at 208.
