How to Write App Screenshot Captions That Sell

Your screenshot captions can make or break your conversion rate. Learn proven headline formulas and copywriting techniques that turn scrollers into downloaders.

Headline Formulas That Work

Benefit + Noun

"Track Your Fitness" not "Activity Tracker." Lead with what the user gets, not what the app does.

Action + Result

"Save Money Automatically". Verb + outcome in 3 words. Clear, compelling, actionable.

Question Hook

"Want to Learn Spanish?". Engages curiosity and targets the user's intent directly.

Number + Benefit

"5-Minute Workouts". Specific numbers add credibility and set expectations.

Social Proof

"Loved by 10M Users". Numbers and social proof build instant trust.

Problem + Solution

"Stop Overspending". Identify the pain point and imply your app solves it.

Subtitle Strategies

Subtitles complement your headline with additional context:

  • Keep subtitles to 5-8 words
  • Use them to add a secondary benefit or feature
  • Don't repeat the headline, expand on it
  • Use simpler language than the headline
  • Consider subtitles optional: sometimes a strong headline alone is better

Examples of good headline + subtitle combos:

  • "Track Your Fitness" / "built-in workout plans"
  • "Save Money Automatically" / "Round-up savings & budgets"
  • "Learn 40 Languages" / "Bite-sized daily lessons"

Caption Mistakes to Avoid

Common caption mistakes that hurt conversion:

  • Feature-focused instead of benefit-focused ("Activity Tracker" vs "Track Your Fitness")
  • Too long (more than 5 words for headlines)
  • Jargon or technical terms users don't understand
  • Passive voice ("Workouts can be tracked" vs "Track Your Workouts")
  • No emotional hook (boring, factual descriptions)
  • Inconsistent tone across screenshots
  • Spelling or grammar errors (instant credibility killer)
