Screenshots and why they convert
5 screenshots of up to 10. The first 3 show in search results when there's no preview video.
#1In search results
5 minutes a day to improve your general knowledge!
- general knowledgein name
- What it shows
- Seven hexagon topic tiles (History, Music, Geography, Health, Literature, Science, Nature) on a purple background with flame icons.
- Why it converts
- States the time cost and the goal in the first frame. The topic tiles show the range of subjects, so a visitor sees what they would learn.
#2In search results
Discover exciting topics and sharpen your mind!
- What it shows
- A course list with illustrated cards, such as a lesson on Alexander the Great, with category tabs and section and lesson counts.
- Why it converts
- Shows real course content, so the visitor sees what a lesson looks like. The caption is broad, so it does not name a specific thing to look for.
#3In search results
Watch and learn! and turn anywhere into your classroom
- What it shows
- A lesson list for a History section with a now-playing card pulled out of the phone frame, showing a progress bar and times.
- Why it converts
- Shows that lessons are watched and listened to in short clips. The enlarged playing card keeps the key control readable at small size.
#4
Enjoy short videos that captivate and inspire
- short videosnot in name
- What it shows
- A player screen with an illustration, a progress bar, playback controls and the next lesson card below.
- Why it converts
- Names the format, short videos, so a visitor knows how lessons are delivered. It repeats the lesson from the previous image, so it adds little new.
#5
Reach your goals! and make learning a daily habit
- daily habitnot in name
- What it shows
- A Missions screen with daily tasks such as “Listen to 02 History Stories”, progress bars and Claim, Go and Claimed buttons.
- Why it converts
- Shows the habit loop: tasks, progress and rewards. It answers why a visitor would come back after day one.
Icon and design system
What makes the page read as one brand at a glance.
- Abstract shapes in a simple layout, with no text or photo.
- The purple and pink match the screenshot palette, so icon and gallery look related.
- It does not say “knowledge” or “learning” on its own, so the name and captions carry that meaning.
- 01
Same frame on most images
A white caption pill, a subline and a purple burst background repeat on most images. Swiping feels like one set.
- 02
Two-line captions
A short bold line, then a second line that adds the benefit.
- 03
Cards pulled out of the phone
Course cards and the now-playing card extend past the device frame.
- 04
Core promise first, then the product
The first image states the time and the goal. The next images show the course list, the player and the missions.
- 05
Topic tiles as a menu of subjects
The first image lists seven subjects, so one frame covers many things a visitor might want to learn.

Where the points are
- Ship an update+15 pts
The last update was 594 days ago. A new version also refreshes the "What's New" notes people read before they download.
- Ask happy users for a rating+10 pts
4.8 stars from 25 ratings. Apple's in-app rating prompt can be shown up to 3 times a year; show it right after a user finishes something in the app.
- Check caption terms against your subtitle and keywords
2 caption terms aren't in the app name: short videos, daily habit. Captions don't count for search; the subtitle and the 100-character keyword field do.
Apply it to your app
A checklist for your next product page update.
- Say the main promise in screenshot 1, including a time or effort cost if you have one.
- Show the range of your content in one frame when it is broad.
- Pull the key card or control past the phone frame so it reads at thumbnail size.
- Put the main idea in the top line of the caption and treat the second line as extra.
- Use the same caption style and background on every image.
- Show retention features, like missions and streaks, after the core use.
How the ASO score works
- 01
App name, 25 points
Up to 10 for how much of Apple's 30 characters it uses, 10 for a brand + keyword structure, 5 when keywords fill half the name or more.
- 02
Screenshots, 35 points
Captions on every image, captions that name searched features, a first screenshot that shows the main use, one design system, readability at search size, and a trust signal.
- 03
Ratings, 25 points
Up to 15 for the average (from 4.0, full marks at 4.8) and 10 for the count (from 1,000, full marks at 100,000 ratings).
- 04
Freshness, 15 points
Full marks for an update in the last 30 days, falling to zero at 180 days. 85+ is excellent, 70+ strong, 50+ fair.
Common questions
What is an ASO score?
A 100-point check of the parts of an App Store page you control: the app name, screenshots, ratings and how recently the app was updated. It's our own scoring rule, shown in full on this page, not a number from Apple. Use it to compare your page with apps that already sell well in your category.
How long can an app name be on the App Store?
30 characters. A common pattern is a short brand followed by the main thing people search for, like “Zeno - Learn General Knowledge”, which uses 30. Apple also gives you a 30-character subtitle and a 100-character keyword field for more terms.
Which screenshots show up in App Store search results?
The first one to three, when the app has no preview video. That's why the first three should cover the main reasons people download. Zeno uses them for general knowledge.
How many screenshots can an iPhone app have?
Up to 10 per device size. Apple recommends focusing each screenshot after the first on one main benefit or feature. Zeno uses 5.
Where do the download and revenue numbers come from?
They're third-party estimates for the US App Store, not figures reported by the developer. Treat them as a sense of scale. Growth compares the latest month with the month before.
Do screenshot captions help an app rank in search?
Apple says search results use text matches in the app name, subtitle, keywords and primary category, plus user behavior such as downloads, ratings and reviews. Captions aren't on that list: they help people who already see the app decide to download. When a caption names something people search for, put that term in the keyword field too.
Where the numbers come from
- Apple: Creating your product page
- App name limit (30 characters), up to 10 screenshots, the first one to three shown in search results, keyword field.
- Apple: App Store search
- Search results use text relevance (name, subtitle, keywords, primary category) and user behavior (downloads, ratings, reviews).
- Apple: Ratings, reviews and responses
- The in-app rating prompt can be shown up to three times in a 365-day period.
- Zeno - Learn General Knowledge on the App Store
- Name, developer, category, icon, screenshots, rating, release and update dates (US storefront), checked Nov 4, 2026.
- Downloads and revenue
- Third-party est. for the US App Store, latest month, pulled Oct 29, 2026. Not reported by the developer.
