The visible above-fold surface is the first 200-250 characters on the App Store.
Used to detect Pattern 1 and brand-position anti-pattern.
Drives the recommended pattern fit.
Renders what users actually see before tapping "More". Truncates at 250 characters with the App Store cutoff visual.
Classifies your opening sentence into one of the 5 patterns from top App Store listings: Brand IS category, Welcome greeting, Action + social proof, Brand + capability + scale, Promise + bullets.
Detects abstract taglines, buried brand names, premature feature lists, unproven superlatives, throat-clearing intros, and keyword stuffing.
Pick your app category and see whether your detected pattern matches the recommended pattern for that user conviction state.
Pure client-side computation with heuristic detection. No credits, no signup, no rate limits.
Drop your App Store description (or just the first 250 characters) into the textarea.
Brand name powers Pattern 1 detection and brand-position check. Category drives the recommended pattern fit.
See the above-fold preview, detected pattern, category match, and which of 6 anti-patterns triggered.
The First Paragraph Hook Analyzer is a free ASO tool that scores the most important part of your App Store description: the 200 to 250 characters above the "More" link. It detects which of 5 opening-sentence patterns (extracted from real App Store listings of Notion, Headspace, Duolingo, Spotify, and YouTube Music) your hook uses, flags 6 common anti-patterns, renders an above-the-fold preview, and recommends a pattern fit based on your app category. No AI, no API call, no signup. Pure client-side analysis.

It analyzes the first 200 to 250 characters of your App Store description (the visible surface above the "More" link), classifies your opening sentence into one of 5 patterns extracted from real App Store listings, flags 6 common anti-patterns, and renders an above-the-fold preview showing what users actually see before tapping "More".
Pattern 1 "Brand IS category" (Notion-style: "[Brand] is [a/an] [category] that helps [audience] [verb list]"). Pattern 2 "Welcome greeting" (Headspace-style supportive opener). Pattern 3 "Action verb + social proof" (Duolingo-style imperative + "most-downloaded" claim). Pattern 4 "Brand + capability + scale" (Spotify-style "With the [Brand] app, you can..."). Pattern 5 "Promise + bullet stack" (YouTube Music-style feature-list opener).
1) Abstract tagline opener ("Transform your life" without category clarity). 2) Brand name buried past 200 characters. 3) Feature list before any positioning sentence. 4) Generic superlatives without proof ("best" without a number or ranking). 5) Throat-clearing intros ("In today's world..."). 6) Comma-heavy keyword-stuffing patterns without action verbs.
Apple truncates the visible description at the "More" link, showing roughly one to two sentences depending on device. Most users decide whether to install from that visible surface without tapping "More". A 4,000-character description has a small effective conversion surface, so the first paragraph carries most of the conversion weight.
No. Apple does not index the App Store description for keyword search on iOS, which is the opposite of Google Play. The first paragraph is conversion craft, not SEO. Apple's own docs warn against keyword-stuffing the description for ranking purposes. For more on the trade-off, see the screenshots vs description ASO trade-off guide.
The Description Optimizer analyzes your whole 4,000-character description for keywords, readability, and ASO best practices, and generates a rewritten version. The First Paragraph Hook Analyzer focuses specifically on the 200 to 250 character above-the-fold surface, which has the highest conversion leverage. Use both: First Paragraph Hook Analyzer to lock the hook, Description Optimizer to polish the rest.
