Title Case Converter
Convert app names and metadata between Title Case, Sentence case, UPPER, and lower.
Capitalization is the cheapest polish an app listing gets — and one of the most commonly botched. App names on both stores conventionally use Title Case (“Habit Tracker & Daily Planner”), subtitles and short descriptions read best in Sentence case, and a stray all-lowercase name or RANDOMLY Capitalized subtitle instantly reads as unmaintained.
This converter switches any text between four modes — Title Case, Sentence case, UPPERCASE, and lowercase — with proper Title Case rules, so minor words like “and”, “of”, and “the” stay lowercased mid-title instead of being naively capitalized.
How to convert text case for app metadata
- 1
Paste your app name, subtitle, or caption into the converter.
- 2
Pick a mode: Title Case for app names, Sentence case for subtitles and descriptions, UPPER or lower for stylistic choices.
- 3
Review the result — brand names with intentional casing (iPhone, eBay) may need manual touch-up after conversion.
- 4
Copy the converted text into App Store Connect or Play Console.
Which case belongs in which metadata field
Store conventions are consistent enough to treat as rules. App names: Title Case, matching how Apple and Google present their own apps and how virtually every top-chart app is styled. Subtitles, short descriptions, and promotional text: Sentence case, because they are phrases and sentences, not proper nouns. Screenshot captions can go either way, but should be consistent across all screenshots — mixed casing across a screenshot set is a surprisingly common and surprisingly visible sloppiness.
All-caps deserves a special warning on Android: Google’s metadata policy prohibits ALL-CAPS words in app titles unless the capitalization is genuinely part of the brand (like “NBA”). An uppercase mode is still useful — for screenshot headlines, badges, and design assets — just not for the Play title field itself.
Why proper Title Case is harder than capitalizing every word
Real Title Case follows editorial rules: capitalize the first and last word and every major word, but keep short conjunctions, articles, and prepositions lowercase — “Recipes and Meal Plans for Families”, not “Recipes And Meal Plans For Families”. The naive capitalize-everything approach is the most common giveaway of machine-generated metadata, and it subtly damages the professional feel that Title Case exists to create.
Case conversion is also locale-sensitive in ways ASCII logic misses. Turkish distinguishes dotted and dotless i (“istanbul” uppercases to “İSTANBUL”), German ß traditionally becomes “SS”, and accented characters must keep their accents through conversion. A converter that handles Unicode casing correctly saves you from shipping a localized title with a broken character in its first word.
Frequently asked questions
Should my app name use Title Case?
Almost always, yes. Title Case is the de facto standard for app names on both stores — it matches user expectations and the styling of virtually every top-ranked app. Deliberate lowercase branding exists, but it is a conscious design decision, not a default.
What is the difference between Title Case and Sentence case?
Title Case capitalizes every major word (“Track Your Habits Every Day”); Sentence case capitalizes only the first word and proper nouns (“Track your habits every day”). Names take Title Case; subtitles, short descriptions, and body copy read more naturally in Sentence case.
Which words stay lowercase in proper Title Case?
Short articles, conjunctions, and prepositions in the middle of the title — “a”, “an”, “the”, “and”, “or”, “for”, “of”, “in”, “on”, “to”. The first and last words are always capitalized regardless. This converter applies those rules instead of blindly capitalizing every word.
Can I use ALL CAPS in my app title?
On Google Play, only if the capitalization is genuinely part of your brand — the metadata policy bans gratuitous all-caps in titles. On the App Store there is no explicit rule, but all-caps names read as shouting and are rare among top apps. Save uppercase for screenshot headlines.
Does capitalization affect App Store search rankings?
No — search matching on both stores is case-insensitive, so “habit tracker” and “Habit Tracker” index identically. Casing is purely a conversion and credibility factor: it changes how professional the listing looks, not where it ranks.
