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
Workout for Beginners No Equipment
- beginnersnot in name
- no equipmentnot in name
- What it shows
- A smiling person seated on the floor in workout clothes, with two laurel badges at the bottom: 4.8 Average Rating and 30M+ Users.
- Why it converts
- States who it is for and what it needs in the first line, so the visitor knows the app without seeing any UI. The rating and user badges sit on the same image, which gives a reason to trust it before the visitor swipes.
#2In search results
Professional Plan for Any Goal
- workout plannot in name
- What it shows
- A grid of day tiles from Day 1 to Day 15 with check marks up to Day 13 and Day 14 outlined, a “No Equipment” tag, and pink and red cards for “28 Days Customized Training” and “28 Days Bed Workout”.
- Why it converts
- Shows a plan as a row of finished days, so the visitor can picture progress. The cards name two plan types they can pick from.
#3In search results
28-Day Fitness Plan
- 28-day plannot in name
- What it shows
- Three week cards, Week 1 to Week 3, each with a cartoon figure and day tiles listing Abs, Butt, Arm, Leg or Full Body with minutes.
- Why it converts
- Spells out what a plan looks like week by week. Session lengths are listed, so the visitor can see how long a day takes. The caption names a plan length people look for.
#4
Wall Pilates Workouts
- wall pilatesnot in name
- What it shows
- Three rows labeled For Butt, For Abs and For Legs. Each pairs a body-area graphic with a photo of a person doing a floor move against a wall.
- Why it converts
- Names a specific workout type instead of a general promise. The three labels split it by body area, and the photos show the move itself.
#5
100+ Workouts
- workoutsnot in name
- What it shows
- A phone showing the Workout tab: a large orange “Turkey Trot Walk at Home!” card with a Join button, then Top challenges, Bed Workout, and Focus zones.
- Why it converts
- Gives the size of the library in the caption and shows a browsable home screen. The seasonal card shows the app has timed content. The phone shows real UI, but the text on it is small.
#6
Hit Focus Area
- focus areanot in name
- What it shows
- A phone with the question “Which areas do you want to focus on?”, five options, two checked, and a cartoon figure with two highlighted spots linked by lines to the checked options.
- Why it converts
- Shows that the plan can be set to the visitor's own choice. The lines tie each option to the figure, so the interaction reads at a glance.
Icon and design system
What makes the page read as one brand at a glance.
- The icon is the app name in white on solid red. It is one element with no extra detail.
- The name carries the icon, so it is text, not a symbol. Text in an icon can be hard to read at the smallest sizes, and it does not say what the app does.
- The red links to the crimson cards and check marks in the second screenshot, so the icon and gallery share a color.
- 01
Printed rating and user count on the first image
The first screenshot carries two laurel badges: 4.8 Average Rating and 30M+ Users. These are the app's own printed claims. They sit at the bottom, below a person photo.
- 02
Photo first, interface later
The first image is a large photo with a caption. Most later images use a pale pink background, a bold black caption, and app visuals.
- 03
Mostly one idea per image
Most captions name a single thing: a plan, a 28-day schedule, wall pilates, library size, or a focus choice.
- 04
Captions that name workouts people want
“Workout for Beginners”, “No Equipment”, “28-Day Fitness Plan” and “Wall Pilates Workouts” are phrases people use for workouts. They also tell a visitor what is inside.
- 05
Cartoon figure as a guide
A cartoon figure appears in the plan and focus-area images. It shows the choice or schedule without a real person's photo and ties the later images together.

Where the points are
- Check caption terms against your subtitle and keywords
7 caption terms aren't in the app name: beginners, no equipment, workout plan, 28-day plan, wall pilates, workouts, focus area. 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 who the app is for and what it needs in the first caption.
- Print your rating or user count on an early image if it is real and you can back it.
- Give each screenshot one idea and one short caption.
- Use the words your users use in captions, such as the workout type or plan length.
- Show a choice or a schedule as UI, so a visitor can picture using it.
- Keep large caption text and one background color across the set, and match the icon to it.
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

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 “JustFit: Lazy Workout & Fit”, which uses 27. 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. JustFit uses them for beginners, workout plan and 28-day plan.
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. JustFit 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.
- JustFit: Lazy Workout & Fit on the App Store
- Name, developer, category, icon, screenshots, rating, release and update dates (US storefront), checked Nov 4, 2026.
- Downloads and revenue
