OpenWhere each tool fits in a release
A store listing has four parts that are easy to get wrong under deadline: the text fields, which have hard character limits; the screenshots, which must match exact pixel sizes; the visual identity — icon, colours, feature graphic — that has to look consistent across all of them; and the privacy policy both stores require you to link.
Start with the character counter while you write your title and subtitle — that's where most of a listing's search ranking comes from. Use the size guide to plan which screenshot sets you actually need before you design any. Pick a palette from your brand colour so screenshots, icon and feature graphic share one look, and generate the privacy policy last, once you know which SDKs your release ships with.
