Screenshots and why they convert
8 screenshots of up to 10, the first 6 shown here. The first 3 show in search results when there's no preview video.
#1In search results
Picture words. Remember them.
- english vocabularynot in name
- What it shows
- A grid of illustrated word cards (such as “prodigious”, “salient”, “winnow”), with the line “Build a brilliant English vocabulary in minutes a day”.
- Why it converts
- Shows the idea in one frame: each word comes with a picture. The big two-part headline says what the app does, and the card grid shows it instead of describing it.
#2In search results
Look up flashcards for any word
- flashcardsnot in name
- What it shows
- Four search chips (an English word, a Japanese word, a phrase and a Russian word) with an arrow to a finished card: a picture, the word “apricity”, its definition and an example sentence.
- Why it converts
- Answers “what if my word isn't in the app?” The mixed-language chips show that any word or phrase can be looked up. The card shows the result, not just the search box.
#3In search results
Master words with spaced repetition
- spaced repetitionnot in name
- What it shows
- A phone showing a review screen with a large green “Remembered +5 XP” card, plus streak, level and deck chips at the top.
- Why it converts
- Names the method people look for. The green check card is easy to read at small size. The streak and level chips hint at a game-like habit loop.
#4
Stay sharp with quick quizzes
- quizzesnot in name
- What it shows
- A flashcard for “demure” with a multiple-choice question, “What's the closest word?”, and a +15 XP label.
- Why it converts
- Shows a short, concrete practice step a visitor can picture doing daily.
#5
Every word, simply explained
- What it shows
- A word page for “petrichor” with pronunciation, a one-line meaning, an overview and example sentences. Text is long and the phone is cut off at the bottom.
- Why it converts
- Promises depth for each word. The headline reads well, but the in-phone text is small and dense, so little of it will read at search-result size.
#6
Discover words curated for you
- What it shows
- A “Made for You” deck showing “58 words, 62% learned”, with word rows marked Confident, Reviewing and New.
- Why it converts
- Shows that the app picks words and tracks progress for you. The status tags make the progress idea visible.
Icon and design system
What makes the page read as one brand at a glance.
- One idea: two stacked cards with a check mark. It points to flashcards and finished reviews.
- Green and blue-purple match the green headline text and the purple-blue phone frames in the screenshots, so icon and gallery look like one brand.
- No text and little detail, so the shape stays clear at small sizes.
- 01
Two-tone headlines
Most captions have a white line and a green line. The green part usually carries the key phrase.
- 02
A small label above most headlines
Most images carry a small grey label such as “Daily practice” or “Personalized”. It adds context.
- 03
One feature per image after the first
Look-up, memory review, quizzes, explanations and a personal deck each get their own image.
- 04
Product art leads the first image
The first image is a wall of illustrated word cards. It shows the app's main idea, pictures for words, before any screen of the interface.
- 05
Same frame and background on most images
A dark green background and a blue-to-purple phone outline repeat on most images, so the set reads as one system.

Where the points are
- Ask happy users for a rating+10 pts
4.8 stars from 168 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
4 caption terms aren't in the app name: english vocabulary, flashcards, spaced repetition, quizzes. 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.
- Show your product's main idea as an image in screenshot 1, not only as text.
- Use a short two-part headline: plain words first, the feature name in a bright color.
- Name the method or feature in the words your users use, such as “spaced repetition”.
- Show the search or input step and its result together, so visitors see what they get.
- Keep in-phone text large. Long paragraphs inside a device frame are hard to read at thumbnail size.
- Reuse one background and one frame style so the set looks like a single story.
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 “VividVocab: Remember Words”, which uses 26. 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. VividVocab uses them for english vocabulary, flashcards and spaced repetition.
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. VividVocab 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.
- VividVocab: Remember Words on the App Store
- Name, developer, category, icon, screenshots, rating, release and update dates (US storefront), checked Nov 4, 2026.
