Screenshots and why they convert
6 screenshots of up to 10. The first 3 show in search results when there's no preview video.
#1In search results
Learn languages by reading books
- learn languagesin name
- reading booksnot in name
- What it shows
- A wall of tilted book covers, including The Great Gatsby, Frankenstein, Alice's Adventures in Wonderland and Don Quixote, under the Eppika logo.
- Why it converts
- Says what the app does in one line: language learning through books. The familiar covers show the content before any app screen appears.
#2In search results
Read in different languages
- read in different languagesnot in name
- What it shows
- A list of five languages with flags (Spanish, English, French, German, Italian) next to a tilted phone showing a “For you” screen.
- Why it converts
- Shows which languages are on offer, so a visitor can check theirs quickly. The flags make each language easy to spot.
#3In search results
Your personalized reading plan
- reading plannot in name
- What it shows
- A tilted phone with a “Continue Reading” shelf of book covers and progress bars, with faded covers behind it.
- Why it converts
- Suggests the app remembers where you are and plans what to read next. The progress bars show this without needing a long caption.
#4
Stories and genres you'll love
- genresnot in name
- What it shows
- A Library screen with genre chips (Nonfiction, History, Quick Reads, Fantasy, Spanish Classics) and rows of covers such as “Best Amazon”.
- Why it converts
- Shows the range of books to pick from. The caption is general, and the genre chips are what make it concrete.
#5
Turn any book into audio
- audionot in name
- booknot in name
- What it shows
- A Don Quixote page in Spanish with one word highlighted, and a player below with a “compuesto / composed” card and play controls.
- Why it converts
- Adds listening as a second way to use the same book. The highlighted word and player show it working in a real reading screen.
#6
Tap a word to translate & listen
- translatenot in name
- What it shows
- An Italian text page with the word “tutto” highlighted and a card showing “all”, a speaker button and a Save button.
- Why it converts
- Shows the core learning action: tap a word, see its meaning, hear it. It closes the set on this feature.
Icon and design system
What makes the page read as one brand at a glance.
- One idea, a parrot over an open book, hints at reading and language before the name is read.
- Bright red, yellow and green on a plain background. The icon colors do not return in the screenshots, which use a cream background and orange accents.
- No text, and the shapes are bold, so it should stay clear at small sizes.
- 01
Same frame on most images
Most images pair a two-line caption with a phone or graphic, on cream. Swiping feels like one story.
- 02
Orange accent on one phrase
Most captions color one phrase orange, such as “personalized” or “audio”. The eye lands on the word that matters.
- 03
Real book covers carry the message
The first image uses well-known titles instead of an app screen. Visitors see what they could read right away.
- 04
Benefit first, then how it works
The set opens with the promise, then languages, plan and library, and ends on tap-to-translate.
- 05
Text-heavy screens are cropped
Some reading screens are cut off by a bottom card, so the one highlighted word and its translation stand out.

Where the points are
- Ask happy users for a rating+9 pts
4.8 stars from 1,962 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
7 caption terms aren't in the app name: reading books, read in different languages, reading plan, genres, audio, book, translate. 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.
- Put your main promise in plain words in the first caption.
- Show the content people get, not only the interface.
- Use one layout and one background across all images.
- Color the key phrase in each caption so it stands out.
- Crop busy screens to the one element the caption names.
- Put the action people repeat most in the closing image.
How the ASO score works

- 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.

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 “Eppika: Read & Learn Languages”, 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. Eppika uses them for learn languages, read in different languages and reading plan.
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. Eppika uses 6.
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.
- Eppika: Read & Learn Languages 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.
