King Post

King Post is a lightweight, local-first Android app that helps you share one selected video to YouTube, TikTok, Instagram Reels, and other compatible Android apps.

Select and preview a video, prepare a reusable caption, and open each platform's editing or upload screen. King Post tracks which platform apps have already been opened and includes a retry notification for Instagram sharing.

Features:
• Select and preview a video
• Copy and reuse one caption across platforms
• Open YouTube, TikTok, Instagram, or another compatible app
• Track which platform apps have been opened
• Retry Instagram sharing from a notification
• No King Post account, advertisements, subscriptions, analytics, or server uploads

King Post does not automatically publish videos on your behalf. Posting is completed inside the selected platform app. Platform behavior may vary by device, Android version, and installed app version.
