The subtitle has two jobs

Apple can use your app name, subtitle, and keyword field for search. Users can see the subtitle in the product page and often in search results. So the line has to do two things at once: add relevant keyword coverage and make a human understand the app faster.

This is where weak listings get lazy. They use the subtitle to say simple, powerful, beautiful, or the same category word already sitting in the title. That may feel safe, but it gives Apple fewer new words to combine and gives the user no sharper reason to care.

  • Use the title for the clearest category or intent phrase.
  • Use the subtitle for a second angle: audience, use case, outcome, or differentiator.
  • Avoid repeating title words unless the phrase truly needs them.
  • Keep unverifiable claims like best, #1, and guaranteed out of the line.

Bad subtitle pattern: brand echo

A lot of indie apps write the subtitle like a tiny billboard for the brand. If the app is called FlowNote, the subtitle becomes Notes for FlowNote users. If the app is called HabitFox, the subtitle becomes Build habits with HabitFox. Nobody searched for that, and nobody learned anything useful.

Bad: HabitFox: Build habits with HabitFox. Better: HabitFox Habit Tracker: Morning routines. The better version is still plain, but plain is fine. It gives Apple habit tracker in the title and morning routines in the subtitle, which opens a more specific use case without wasting space on the brand twice.

For a new app, the brand usually has no search demand yet. Treat the subtitle like rented space in a very expensive airport. Every word needs a job.

Subtitle examples by app category

Habit app: weak subtitle, Simple daily habit builder. Better subtitle, Morning routines. If the title already includes Habit Tracker, the better line adds a concrete moment instead of repeating daily habit language.

Budget app: weak subtitle, Track money and expenses. Better subtitle, Bills and cash flow. Pair that with a title like Budget Planner and you get more useful combinations: budget bills, cash flow planner, money bills, expense planner if expense lives in the keyword field.

Focus timer: weak subtitle, Powerful focus timer. Better subtitle, Deep work sessions. Powerful does not tell the user anything. Deep work sessions points to a real job the app helps with.

Sleep sounds app: weak subtitle, Relaxing sleep sounds. Better subtitle, Rain, fan, and white noise. If Sleep Sounds is already in the title, the subtitle can carry sound types users actually search for and recognize instantly.

Language app: weak subtitle, Learn any language fast. Better subtitle, Travel phrases first. The second version is narrower, more believable, and easier to match with screenshot copy.

When to choose keyword coverage over conversion copy

The annoying answer: it depends on what the title already covers. If your title is mostly a brand name, the subtitle probably needs the category. If your title already has the category, the subtitle can move into use case or outcome territory.

Example one: Luma: Photo editor. That subtitle is doing necessary category work because the title alone tells Apple and users almost nothing. Example two: Luma Photo Editor: Film presets. Now the subtitle gets to be more specific because the title already handled the broad category.

Do not try to make the subtitle carry everything. Thirty characters cannot explain your whole product, your whole keyword strategy, and your whole positioning. Pick the missing piece that matters most.

  • Brand-only title? Use the subtitle to name the category or main job.
  • Category title? Use the subtitle to add use case, audience, or outcome.
  • Crowded category? Go narrower than the obvious head term.
  • Weak screenshots? Make the subtitle and first screenshot tell the same story.

A 10-minute subtitle audit

Put your title, subtitle, and 100-character keyword field in one note. Circle every repeated word. If the subtitle repeats the title, rewrite the subtitle first. That change is visible to users and can free the keyword field to cover missing pieces instead of patching vague metadata.

Then test the line against a stranger question: would someone understand the app faster after reading this? If not, it is probably decorative. Decorative copy is expensive in App Store metadata.

A good subtitle is not clever. It is compressed. It adds one useful idea the title did not already say. That is the bar.
