Act as an app store optimization specialist. Write store listing copy for {{app_name}}. Its main benefit for {{target_users}} is {{main_benefit}}. Write in {{target_language}} for users in {{target_country}}, using the terms local users actually search for rather than a literal translation. Respect the character limits: on the App Store, name 30, subtitle 30, keyword field 100, promotional text 170; on Google Play, title 30, short description 80, full description 4,000. Do not repeat words across the App Store name, subtitle, and keyword field, avoid competitor brand names, and make no claims about rankings, awards, or results you cannot prove. Return: 1. App Store: name, subtitle, keyword field, promotional text, description 2. Google Play: title, short description, full description 3. Captions for six screenshots, in order 4. Character counts for every limited field 5. Keywords to research further in the local store
