App Store and Google Play Character Counter

App Store limits: app name 30 characters, subtitle 30, keyword field 100, promotional text 170, description 4,000. Google Play limits: title 30, short description 80, full description 4,000. Type or paste below to see live counts and the format problems that get titles rejected or waste space.

0 / 30 (30 left)

Weighted most for search. Brand plus what the app does.

0 / 30 (30 left)

Indexed. Use words that are not already in the title.

0 / 100 (100 left)

Hidden from users. Commas, no spaces, no repeats of title or subtitle words.

0 / 170 (170 left)

Not indexed. Can be changed any time without a new build.

0 / 4000 (4000 left)

Not indexed by Apple. Write it for people deciding to install.

Counts update as you type.

Runs in your browser. Nothing you type is sent or stored.

How it works

Three steps, no sign-up

01

Pick a store

The App Store has five text fields with limits; Google Play has three. Switch between them and your text is kept.

02

Type or paste your listing

Each field shows a live count against its limit, whether the store indexes it for search, and what to fix.

03

Fix the flags

Banned words in Play titles, emoji, ALL CAPS, subtitle words that repeat the title, spaces in the keyword field. If the title runs long, you get shorter versions in the Brand: Descriptor shape.

Worked example

A worked example

A Google Play title written the way many first launches are, checked against Play's metadata policy.

In: Play titleBEST Free Habit Tracker App 🔥
Out: Length29 of 30, fits, but will not pass review
Out: Flags"best" and "free" are promo words, emoji not allowed, ALL CAPS word
Out: RewriteHabitly: Habit Tracker (22 of 30, no flags)

Google Play's metadata policy bans ranking, price and promo words, emoji and ALL CAPS in app titles. Fixing them before you submit avoids a rejection.

Frequently asked

Questions, answered

Updated October 2026

30 characters. The subtitle is also 30 characters. Both are indexed for search, and Apple weights the app name most.
30 characters. Google reduced it from 50 in 2021 and its metadata policy also bans emoji, ALL CAPS (unless it is your brand) and words like "best", "#1", "top", "free" or "new" in the title.
80 characters. It shows near the top of your listing and Google indexes it for search, so lead with your main keyword phrase.
No. Apple ranks on the app name, subtitle and keyword field (plus things like in-app purchase names), not the description. Google Play does index the full description.
This counter counts characters the way you see them, so one emoji counts once. Some emoji are built from several code points and a store console may count them as more, so leave a little room if you use them.
"Brand: what it does", for example "Habitly: Habit Tracker". The descriptor is what people search for, and keeping it inside 30 characters means none of it is cut off.
