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
Speak it like you mean it.
- language learningnot in name
- What it shows
- A Spanish phrase lesson in colored text with a pronunciation tip, on a dark background. A banner at the bottom reads “The Highest Rated Language Learning App”.
- Why it converts
- Shows a real lesson screen, not a logo, so a visitor sees what the app does. The banner is the app's own claim and names the category.
#2In search results
Choose from over 70 languages
- languagesin name
- What it shows
- A language home screen for Spanish, Latin American, with a Resume button, over a photo of a person in a patterned dress.
- Why it converts
- Gives a number a visitor can check against the language they want. The photo adds warmth, but the lesson screen from the first image is not repeated.
#3In search results
Tap every word for pronunciation
- pronunciationnot in name
- What it shows
- A lesson card with an English and a Spanish sentence, each word in its own color, and a pronunciation bubble over one word.
- Why it converts
- Names one action and shows it. The caption words match what a learner may look for, and the bubble makes the action easy to picture.
#4
Match your voice to native speakers
- native speakersnot in name
- What it shows
- Two audio waveforms for the word “Hola.” in a card that breaks out of the phone, with a hold-to-record button.
- Why it converts
- Turns a vague promise into a clear step: record, then compare. The enlarged card keeps the waveforms readable at small size.
#5
Dive deeper with cultural context
- cultural contextnot in name
- What it shows
- A culture note card about greeting customs in Spanish-speaking countries, on a yellow background.
- Why it converts
- Shows a second kind of value beyond words and grammar.
#6
Practice listening and reading skills
- listeningnot in name
- readingnot in name
- What it shows
- A list of Spanish lines with play buttons, a Listen and Apply tab, and word counts, on an orange background.
- Why it converts
- Closes on the two skills a learner expects to train.
Icon and design system
What makes the page read as one brand at a glance.
- One shape, a blocky letter M, stands for the brand name.
- The mix of green, yellow, red, blue and black tiles is the same palette family as the colored backgrounds in the screenshots.
- Fine tile detail may blur at the smallest sizes, but the large M shape stays clear.
- 01
Two-line captions with bold emphasis
A first line sets up the idea and a bold second line names it, such as “pronunciation” or “native speakers”. The bold part is what the eye reads first.
- 02
One skill per screenshot
Most images cover one thing: speaking, language choice, pronunciation, voice matching, culture, listening and reading.
- 03
Background color changes, layout stays
Backgrounds in blue, green, yellow and orange mostly share one layout: caption on top, phone below. The color changes while the system stays similar.
- 04
A card that breaks out of the phone
On the voice screen, the key card breaks out of the phone frame, so the waveforms stay readable.
- 05
A printed claim in the first image
The first image carries the app's own claim, “The Highest Rated Language Learning App”, in a banner under the phone.

Where the points are
- Use the rest of the app name+7 pts
5 characters are free. Add the next most important search term.
- Ask happy users for a rating+2 pts
4.8 stars from 44,347 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: language learning, pronunciation, native speakers, cultural context, listening, reading. 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 a real use of the app in the first image, not only a logo.
- Name your category in the first image so visitors do not have to guess.
- Give each screenshot one skill or benefit, and name it in the caption.
- Use a short first line plus a bold keyword line so the key words stand out.
- Enlarge the card or number you want read, so it holds up at small size.
- Vary the background color but keep layout and type fixed.
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 “Mango Languages: Learning”, which uses 25. 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. Mango Languages uses them for language learning, languages and pronunciation.
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. Mango Languages 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.
- Mango Languages: Learning 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.
