AdaptlyPost runs your social calendar on autopilot, and it is the deal I actually bought this week. The AppSumo lifetime starts at $49 and I took license tier 2 on camera.
The thing that sold me is where the limits sit. The monthly credits cap the AI, not the scheduling. There is no limit on how much you schedule or post, which is the part I actually want it for. On the $49 tier the credits work out to roughly 50 generated images a month, and if you are buying this to write your posts for you that is thin. I am not. I am buying it to post.
What gave me pause is the age. The company is about nine months old and ships weekly. Weekly shipping is a good sign on its own, but a nine-month-old company holding your posting schedule is a real risk, and the honest answer is that lifetime means their lifetime.
The other thing I looked for was the approvals. If a scheduler does not have standing approval from the platforms it posts to, the whole thing falls over the first time an API changes. AdaptlyPost posts through its own integrations rather than asking you to bring keys.
My verdict: 5 stars, bought. I have not run it in anger yet, so treat the score as confidence rather than experience. I will report back next week with what I found once it is set up.
