Tips
Subtitles that help search and conversion
Lead with outcome. Users skim title + subtitle together in search. A benefit clause beats a feature list in 30 characters.
Do not repeat the title. Apple already indexes title words. Pair this with the keyword optimizer for the hidden keyword field.
Test on device. Check truncation in App Store search on a real iPhone before you submit.
FAQ
Quick answers
- What is the App Store subtitle character limit?
- Apple limits App Store subtitles to 30 characters. Subtitles appear under your app title in search results and on the product page. They are indexed for keywords, similar to the title field.
- Should the subtitle repeat my app name?
- Usually no — Apple already indexes your title. Use the subtitle for a benefit phrase or secondary keyword your 30-character title cannot fit. Repeating the brand wastes scarce characters.
- Can I use emojis in an App Store subtitle?
- Yes, emojis count toward the 30-character limit (often as one character each). Consumer and lifestyle apps use them sparingly; productivity and finance apps typically stay with plain text.
- Does Google Play have a subtitle field?
- Google Play uses a 30-character short description with a similar role. The copy you write for Apple often works on Play, but localize per store if your markets differ.
- How is this different from the keyword field?
- The subtitle is visible to users; the 100-byte keyword field is hidden. Both are searchable. Put human-readable value in the subtitle and reserve the keyword field for terms not already in title or subtitle.
- Does this tool save my inputs?
- No. Subtitle suggestions are generated entirely in your browser. Nothing is uploaded or stored.
