Keyword field packer

The App Store's 100-character keyword field is the tightest and most wasted space in ASO. Enter your title and keywords and we'll pack it by Apple's indexing rules. No signup, and nothing is sent to a server.

App title

0/30 characters. Words in the title are not repeated in the field.

Subtitle (if any)

0/30 characters. The subtitle is indexed too, so its words are skipped as well.

Keywords you're targeting

One per line, or comma-separated. 0 terms read.

What the packing is based on

Title, subtitle and the keyword field are indexed TOGETHER — a word in the title is never written into the field a second time.
Words recombine across fields: with "dream" and "dictionary" entered separately you also match "dream dictionary". That's why phrases are split into unique words.
The separator is a comma with no space. A space costs a character and buys nothing.
Your category, developer name and app name are already indexed; they don't need to be in the field.

The calculation runs in your browser. Your title and keyword list are never sent to any server — handing an unreleased version's keywords to a tool is usually not something you want.

This is the same calculation as the metadata auditor in the dashboard. There we also measure your rank, the apps above you, and whether the term is actually searched.
