Screenshot 1 doesn't say what the app does

1. Check the problem

If a user reads only screenshot 1 and still can't say what the app does, that's a conversion bug, not a marketing one. Lead with big overlay text stating the value, like "Track your training, no spreadsheet needed."

2. Use the prompt

Rewrite my App Store screenshot 1 so a user who reads only that one screen can say what [app] does in a sentence. Make the value-prop text the hero, like a big overlay reading 'Track your training, no spreadsheet needed', with a smaller phone mockup behind it. Give me 3 overlay headline options.

3. Verify the fix

Review the proposed diff, run the relevant checks and exercise the original failing flow before merging.
