Screenshots and why they convert
7 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
Discover what your mind can do
- What it shows
- The Lumosity wordmark, a laurel badge reading “Over 100 million users”, and a Daily Workout card with a Start button above a list of More Workouts (Math, Language).
- Why it converts
- The user-count badge sits in the first frame, and the Daily Workout card shows the main action. The headline is general, though, so it does not say what the app trains.
#2In search results
Train Memory, Attention, and more
- memorynot in name
- attentionnot in name
- What it shows
- A game library grouped under Memory (Memory Match, Memory Matrix), Attention (Feel the Beat, Assist Ants) and Problem Solving, each game with a colorful tile.
- Why it converts
- Names the skill areas people look for and shows the range of games in one view. The caption is specific where the first headline was not.
#3In search results
Daily workouts to train your brain
- train your brainnot in name
- What it shows
- A Splitting Seeds game page with an illustration, a short description, a high score of 17,000 points, a best stat of 19 seeds and a row of badges with “85 plays”.
- Why it converts
- Shows the daily habit and a sense of progress through scores and badges. The caption states the main use in plain words.
#4
Track your progress on each skill
- track progressnot in name
- What it shows
- A My Stats screen with a Lumosity Performance Index: an overall bar at 1154 and bars for Memory, Speed, Flexibility, Problem Solving, Attention and Math.
- Why it converts
- Gives a visitor a reason to keep using the app: a number they can watch change. The bars are large, so the scores stay readable when small.
#5
Train math skills and vocabulary
- math skillsnot in name
- vocabularynot in name
- What it shows
- A live math game: falling drops with sums such as 9 ÷ 3, a score of 11000 and a number pad at the bottom.
- Why it converts
- Shows real play, not a menu. It also names two skills, math and vocabulary, that people look for in a brain app. Only math is visible in the picture.
#6
Get insights into your strengths
- insightsnot in name
- What it shows
- Game Strengths and Game Progress lists with bars and scores, a green “Strongest” tag and LPI increase values.
- Why it converts
- Shows that the app gives feedback on how you do, a benefit beyond the games.
Icon and design system
What makes the page read as one brand at a glance.
- One symbol, a head profile with a brain, points to a thinking or mind app.
- Orange gradient matches the orange words in the screenshot captions, so icon and gallery read as one brand.
- No text and little detail, so the shape holds at small sizes.
- 01
Two-tone captions
Dark navy serif type with key words in orange. The orange words are the ones the eye lands on.
- 02
Proof in the first frame
A laurel badge with “Over 100 million users” sits above the phone in screenshot 1, where search results show it. It is the app's own claim.
- 03
One screen per idea
Most images have one job: skill areas, daily workout, progress, math play, strengths. Swiping reads as a short tour of the app.
- 04
Same frame on most images
Most images use a cream background, a peach glow behind the phone, and the device cropped at the bottom. The screen inside changes.
- 05
Progress as a feature
Two images show scores, bars and badges. The pitch is not only games but seeing how you improve.

Where the points are
- Ask happy users for a rating+2 pts
4.7 stars from 130,941 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: memory, attention, train your brain, track progress, math skills, vocabulary, insights. 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 the main action or a clear one-line use in screenshot 1, not only a general headline.
- Place a user count or award in the first frame if you can state it truthfully.
- Name the skills or topics in the caption, in the words your users use.
- Give each screenshot one idea and one caption.
- Show real in-use screens, such as a game or a results view, not only menus.
- Reuse the icon color in the caption highlights so the set looks like one brand.
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 “Lumosity: Brain Training Games”, 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. Lumosity uses them for memory and train your brain.
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. Lumosity uses 7.
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.
- Lumosity: Brain Training Games 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.
