Screenshots and why they convert
10 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 More out of Less Sleep
- less sleepnot in name
- What it shows
- A large headline that runs across this image and the next, over a phone showing a blue smiling character, with “Supported by Samsung C-Lab” and “Google for Startups” below.
- Why it converts
- The headline makes a promise rather than naming what the app does, and the first frame has no UI. The two named programs are a trust signal on the first image. The headline continues onto the next image, so on its own this frame reads as cut off at search-result size.
#2In search results
A Powerful Sleep App Backed by Neuroscience
- sleep appnot in name
- What it shows
- The end of the split headline, “Scientific American” and “National Institutes of Health” wordmarks, and a laurel badge reading “A Powerful Sleep App Backed by Neuroscience”.
- Why it converts
- Names the app's category in plain words and puts outside organization names next to it. The badge is the app's own claim, so a visitor should check it; the page gives no detail on what the sources say.
#3In search results
51% Increase in Deep Sleep
- deep sleepnot in name
- What it shows
- A phone showing a sleep timer, “Sleep ends at 08:00 am”, under the caption “51% Increase in Deep Sleep”.
- Why it converts
- A specific number is a strong hook, but the image gives no source or method for it. It is the app's own printed claim. The screen shown is a timer, which does not show where the number comes from.
#4
Personalized Sleep Sounds
- sleep soundsin name
- What it shows
- A “Tell us about your day” screen with mood and pre-bed activity chips, some selected in blue. Text says answers help generate Monaural Beats.
- Why it converts
- Names the main thing the app is for, sleep sounds, and shows how it personalizes them. The selected chips make the input step easy to picture.
#5
Gain Insights on Your Sleep
- sleepin name
- What it shows
- Sleep stats cards: average sleep time 5h 24m, sleep score A+ “top 5%”, bedtime 11:40 pm, wake-up 7:02 am, and a bar chart. A blue character holds books on top.
- Why it converts
- Shows what a user gets back after using the app, with large numbers that read well. The character adds a friendly tone to a data screen.
#6
Better Sleep with Sleep Articles
- sleep articlesnot in name
- What it shows
- A grid of illustrated article thumbnails in many colors, with the blue character at the bottom wearing red glasses.
- Why it converts
- Shows a content feature that the other images do not. The illustration style matches the character used elsewhere.
Icon and design system
What makes the page read as one brand at a glance.
- Two simple shapes, a moon and a sleepy face, hint at “sleep” without any text.
- The navy and blue match the dark background and blue highlights in the screenshots, so icon and gallery look like one brand.
- The blue character is the same one that appears in the screenshots, which makes the app easy to recognize.
- The face is simple enough to read at small sizes. Dark-mode and tinted looks were not checked.
- 01
Trust before the product
The first two images show Samsung C-Lab, Google for Startups, two outside organization names and a neuroscience badge before any feature screen. These are the app's own claims.
- 02
One headline across two images
The first headline runs from image 1 into image 2. Swiping feels continuous, but image 1 alone does not give a full sentence in search.
- 03
Two-tone captions
Most captions pair white text with blue or gray text.
- 04
A mascot as the brand
The blue character appears in the icon and in several screenshots. It softens data-heavy screens and ties the set to the icon.
- 05
Dark theme on most images
A near-black background suits a bedtime app and keeps the set visually consistent.

Where the points are
- Ask happy users for a rating+14 pts
4.6 stars from 125 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.
- Use the rest of the app name+2 pts
6 characters are free. Add the next most important search term.
- Check caption terms against your subtitle and keywords
4 caption terms aren't in the app name: less sleep, sleep app, deep sleep, sleep articles. 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 what the app does in the first image, not only who backs it.
- Keep each image readable on its own, even if you split a headline across two.
- Print a trust signal only if you can back it up, and say where a number comes from.
- Name the feature in a large, short caption, using the words your users use.
- Make the key number on a data screen big enough to read at thumbnail size.
- Reuse one character or color from the icon across the screenshots.
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 “Renight: AI Sleep Sounds”, which uses 24. 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. Renight uses them for less sleep, sleep app and deep sleep.
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. Renight uses 10.
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.
- Renight: AI Sleep Sounds 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.
