Falou - Fast language learning App Store optimization
A Education app's App Store page, taken apart: the screenshots and why each one helps people decide to download, the icon and design system, and an ASO score out of 100.

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
Get fluent much faster in 2024.
- fluentnot in name
- fasternot in name
- What it shows
- A woman holding a phone and a mug, with a yellow rising arrow behind her and the Falou mascot beside her. Two badges: “Apps We Love, 100+ countries” and “#1 Education, 2020 2021 2022 2023”.
- Why it converts
- Opens with the outcome a learner wants, then backs it with two printed badges. The “#1” is the app's own claim. The first image shows no app screen, so how it works comes next.
#2In search results
Master your speaking skills
- speakingnot in name
- What it shows
- Step 1 of a numbered flow. A phone card with a smiling person's photo, the phrase “How are you?” and a round microphone-style button.
- Why it converts
- Names the first skill and shows the speaking prompt in use. The step number makes the set read as a path.
#3In search results
Improve your pronunciation
- pronunciationnot in name
- What it shows
- Step 2. A Spanish sentence shown twice: “Correct” with “gusta” in green, and “You said” with “gustó” in red.
- Why it converts
- The correct and incorrect lines side by side show what the feedback looks like. The caption names a feature learners look for.
#4
Develop your writing skills
- writingnot in name
- What it shows
- Step 3. A French chat bubble “Salut! Ça va?”, a typed reply with one word struck through, and an on-screen keyboard.
- Why it converts
- Shows writing practice as a chat. The struck-through word shows that the app corrects the learner.
#5
Have fun learning 30 languages
- 30 languagesnot in name
- What it shows
- Step 4. A smiling person's photo above Chinese characters, with three boxes holding question marks.
- Why it converts
- States the language count in the caption. The unfinished word puzzle suggests a game-like exercise.
#6
Get unique certificates
- certificatesnot in name
- What it shows
- Step 5. A “Certificate of Practice” reading “3,600 minutes of English practice”, with a seal, and a row of three slots, one filled and two locked.
- Why it converts
- A reward feature that gives learners a goal to keep going. The locked slots hint at more certificates to earn.
Icon and design system
What makes the page read as one brand at a glance.
- One character face is the only subject, so the icon is simple and easy to spot.
- No text, so nothing needs to be read at small sizes.
- The same monkey appears on the first screenshot and the blue matches its highlight color, so icon and gallery look related.
- The icon does not say “language learning” by itself. The name and the first caption carry that.
- 01
Outcome first, then the steps
The first image states the result (“Get fluent much faster”). The next images are numbered steps for speaking, pronunciation, writing, languages and certificates.
- 02
Highlighted keyword in most captions
A black verb line, then one word in white on a colored block.
- 03
One color per image
Blue, green, purple, orange and cyan backgrounds change per image, while layout and fonts stay much the same and the step badge repeats on the numbered images. The set reads as one system.
- 04
Real photos on a phone card
Some steps show a smiling person above a simple exercise. The card keeps the app screen plain and easy to read.
- 05
Printed claims up front
The first image carries “Apps We Love” and “#1 Education” badges as the app's own claims. They sit before any feature is shown.

Where the points are
- Check caption terms against your subtitle and keywords
7 caption terms aren't in the app name: fluent, faster, speaking, pronunciation, writing, 30 languages, certificates. 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.
- Say the result the user wants in screenshot 1, in a short line.
- Put proof such as awards or rankings next to that line, and keep it specific.
- Give each later screenshot one skill or feature and one short caption.
- Make one word in each caption stand out with a color block.
- Number the steps when the images tell a sequence.
- Change the background color per image only if layout, fonts and caption style stay 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 “Falou - Fast language learning”, 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. Falou uses them for fluent, speaking 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. Falou 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.
- Falou - Fast language 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.
