ASO Metadata Audit Tool
Paste App Store or Play Store title, subtitle, and description to check character limits — free ASO metadata audit.
Why run an ASO metadata audit?
Titles and subtitles are your first keywords and your first conversion line. Too long and stores truncate or reject; too short and rivals own the remaining characters. This free ASO metadata audit tool can load a live App Store or Play Store URL, or you can paste a draft title, subtitle (or short description), and description. It compares those fields to official character limits plus length ranges common in stronger listings.
App Store vs Play Store character limits
Apple uses title + subtitle (30/30) plus promotional text and a long description (up to 4,000). Google Play uses title + short description (30/80) and a longer full description (up to 4,000). Switch the store toggle above so title character limits and benchmarks match the store you are shipping to.
What to do next
When lengths look healthy, run Analyze My App for a listing overview, or generate drafts with Metadata AI. Need AI rewrites inside a project? Create a free Nakxi account .
Metadata Audit FAQ
What is an ASO metadata audit?
An ASO metadata audit checks your App Store or Play Store title, subtitle or short description, and long description against character limits and length benchmarks competitors typically use — so you know what to tighten before you publish.
Does this tool fetch my live listing?
Yes. Paste an App Store or Play Store URL and Nakxi loads the live title, subtitle or short description, and description for length checks. You can still paste draft copy by hand. Apple does not always publish the subtitle in the public lookup API, so that field may stay empty until you type it.
What are the store character limits?
App Store: title 30, subtitle 30, promotional text 170, description up to 4,000. Google Play: title 30, short description 80, full description up to 4,000. This audit flags over-limit and under-used fields — including title character limits for both stores.
How is this different from Analyze My App?
This page focuses on pasted metadata lengths vs limits and benchmarks. Analyze My App is the free ASO-score hub — it blends listing, screenshot layout heuristics, and competitive signals from your live store URL into one Nakxi ASO score.
