Unlock Your Child’s Reading Potential
- readingnot in name
- What it shows
- A tilted phone with a profile picker for three children, book covers, and a Go button, on a yellow background.
- Why it converts
- The caption is a broad promise and does not say what the app does. The picker hints at child profiles, but a visitor must work out the rest.
#2In search results
Award Winning Reading & Comprehension App
- readingnot in name
- comprehensionnot in name
- What it shows
- A tilted phone with a parent dashboard: a weekly bar chart and bars for reading time, accuracy and comprehension.
- Why it converts
- The caption names the two skills the app covers, and “Award Winning” is the app’s own claim. The dashboard is shown before the reading itself.
#3In search results
Personalized Reading Program with real-time A.I. reads, listens, and corrects
- reading programnot in name
- What it shows
- A story page from The Wizard of Oz with an illustration, highlighted sentence text, a progress bar, and mic and speaker buttons.
- Why it converts
- Shows the core activity: a child reads a story aloud in the app.
#4
Advance Comprehension skills with Interactive Voice-Based Questions and Answers in every story
- comprehensionnot in name
- What it shows
- A question screen asking what was found at the end of the yellow brick road, with a book cover, an answer, and mic and speaker buttons.
- Why it converts
- Shows one concrete feature, questions after a story.
#5
See your child improve in accuracy, fluency, and comprehension
- fluencynot in name
- accuracynot in name
- What it shows
- The parent dashboard in full: reader and parent mode toggle, weekly chart, and totals for reading time, accuracy and comprehension.
- Why it converts
- Speaks to the parent as the buyer and names the outcome they want to see. It repeats the dashboard from the second image.
#6
Practice, learn, and grow vocabulary skills with a personalized list
- vocabularynot in name
- What it shows
- A vocabulary list with a search box, A-Z sorting, and the word “Fantasy” opened to a definition with a speaker button.
- Why it converts
- Adds a separate feature, vocabulary, that people may look for on its own. The open word card shows how it works.
Icon and design system
What makes the page read as one brand at a glance.
- One symbol, a book with a bookmark ribbon, says “reading” without text.
- Yellow, teal and coral match the backgrounds used in the screenshots, so icon and gallery read as one brand.
- The book is tilted and the pages overlap, which adds some detail at small sizes.
- 01
Rotating background colors
Yellow, teal and coral backgrounds alternate with wavy shapes and white captions. The color changes, but the layout is largely the same.
- 02
Parent and child both addressed
Some captions speak to the child’s reading, others to what the parent can see. Both groups are in the buying decision.
- 03
Dashboard shown twice
The same parent dashboard appears in two images. A repeat uses a slot the app could spend on another feature.
- 04
Long captions
Several captions run to three or four lines.
- 05
Recognizable story content
The reading and question screens use The Wizard of Oz. A familiar story helps a visitor picture a child using the app.

Where the points are
- Ask happy users for a rating+7 pts
4.6 stars from 25,365 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
6 caption terms aren't in the app name: reading, comprehension, reading program, fluency, accuracy, vocabulary. 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.
- Make screenshot 1 say what the app does, not only what it promises.
- Keep each caption to one idea and a few words.
- Check white captions on light backgrounds like yellow. Raise contrast until they read at thumbnail size.
- Show a feature once. Use the freed slot for a different reason to install.
- If two groups decide, such as parent and child, write captions for each.
- Use familiar content in your UI shots so a visitor understands the activity at once.
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 “Readability - Learn to Read”, which uses 27. 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. Readability uses them for reading, reading and reading program.
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. Readability uses 8.
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.
- Readability - Learn to Read 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.
