Zup is a free native iPhone app that turns photos and ideas into editable social posts. Start with a photo or a thought, generate a caption, adjust its tone and length, and review it in a live platform preview before sharing. You can customize emojis and hashtags, proofread your writing, and schedule reviewed posts to X or LinkedIn.

Built by a solo, self-funded maker, Zup helps creators and small business owners find words for the moments they want to share while keeping the final say over every post. All features are free, with an optional one-time tip.
