Short version: this probe lets you compose App Store–sized PNGs in your browser. The 6.9-inch size is free; other sizes open with a future one-time pack.
What it does. You upload a screenshot, pick a template and size, edit marketing text, and export a PNG at App Store Connect pixel dimensions (RGB, no alpha).
Free size. 6.9-inch (1320×2868) exports are unlimited and free during the probe. No account required for export.
Paid sizes. 6.5-inch, 5.5-inch and iPad 13-inch sizes are locked until one-time packs launch. Joining the waitlist does not charge you.
Your content. You are responsible for the screenshots and copy you add. Do not upload content you do not have rights to use.
No warranties. The tool is a probe provided as-is. Always check that App Store Connect accepts your export before relying on it for a release.
Fair use. Do not abuse the waitlist or telemetry endpoints. We may ignore or remove abusive entries.
