Schedule Instagram posts.
Photos, carousels, Reels and Stories go out on their own at the time you pick. PostFlow checks the size and caption first.
What you can schedule

Questions
Does a personal Instagram account work?
No. Instagram only lets apps post to Business and Creator accounts. Switching is free and you can switch back any time.
Why does my photo need cropping?
Instagram only takes photos between 4:5 and 1.91:1. If yours is taller, PostFlow shows the problem and crops a copy for Instagram. Other platforms keep the original.
Can I put hashtags in the first comment?
Yes. Write them in the first comment box and PostFlow posts the comment right after the post goes out.
Can I schedule Stories?
Yes, a photo or a video of up to 60 seconds. Stories have no caption.
