Assets & Settings
What this tool does
Free App Store keyword checklist for iOS developers and mobile marketers. Paste your title (30 chars max), subtitle (30 chars max) and keywords field (100 chars max) and the tool flags common ASO mistakes in real time: keywords that overlap with your title or subtitle (Apple already indexes those words, so duplicates waste precious space), spaces after commas that iOS silently strips, duplicate entries within the keyword field, and characters over the limit. A structured asset checklist covers icon, screenshots, preview video, age rating, privacy policy URL and support URL so nothing slips through before you hit Submit. A live readiness score at the top summarises how launch-ready your listing is. 100% client-side, nothing is uploaded or stored.

Real-world use cases
Audit keyword field before App Review submission
Paste your app title, subtitle and keyword field into the three inputs. The tool instantly flags any words that appear in both the keyword field and your title or subtitle — Apple already indexes those, so they are wasted space. Fix the overlaps and free up characters for fresh search terms that expand your reach without touching your title copy.
Plan ASO from scratch while writing the store listing
Open the checklist at the start of the submission workflow. Tick off each asset as you create it — icon, screenshots, preview video — so nothing slips through before you click Submit for Review. The live character counters for title, subtitle and keyword field keep you within Apple's limits from the first draft, not as a last-minute scramble.
Common pitfalls
Repeating keywords from the title or subtitle in the keyword field. Apple indexes all three fields, so duplicates waste your 100-character budget without adding any new search visibility.
Adding a space after each comma in the keyword field. App Store Connect silently strips those spaces, which can cause a keyword to lose its leading character and fail to match user searches.
Using the keyword field for competitor brand names. Apple's guidelines explicitly prohibit this and it is a common reason for App Review rejection.
Privacy
All analysis runs in your browser. The title, subtitle, keywords, description and promotional text you enter are never sent to any server. The shareable link encodes those inputs in the URL query string — share only links you are comfortable with others seeing.
