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
LOSE WEIGHT & GAIN MUSCLE
- lose weightnot in name
- gain musclenot in name
- What it shows
- A heavier man faded in the background and a muscular man in front with glowing outlines on his shoulders and torso, under a small “MUSCLE BUILDER” tag, with a “2025 Fitness App” laurel badge at the bottom.
- Why it converts
- Shows the result a visitor wants before any app screen. The goal is stated in large type. The laurel badge is the app's own claim and no source is printed, and no app screen appears yet.
#2In search results
PERSONALIZED PLANS
- personalized plansnot in name
- What it shows
- A tilted phone with a week strip, a “Day 2 Sculpted Full Body” card marked Intermediate, 20 mins, and a green START button.
- Why it converts
- First look at the product itself. A concrete card with level, length and a start button shows what a plan looks like. “Personalized” is a promise the image doesn't prove.
#3In search results
FOR EVERY GOAL
- What it shows
- A setup screen with focus areas (abs, chest, arm, back, butt, leg), fitness goals (lose weight, build muscle) and levels (beginner, intermediate, advanced).
- Why it converts
- Lets a visitor find their own case: body part, goal and level. The caption is generic, though.
#4
HIT TARGET AREA
- target areanot in name
- What it shows
- Four rows, each with a muscular body photo on the left, a line drawing of an exercise on the right, and a green label: abs, arm, chest, back.
- Why it converts
- Pairs each muscle group with an example move, so the visitor sees what the app teaches. Green labels repeat the caption color and keep the rows easy to scan.
#5
FITNESS CHALLENGE
- fitness challengenot in name
- What it shows
- A stack of challenge cards: Full Body Challenge (28 days), Lower Body Blast (28 days), Upper Body Shred (5 days).
- Why it converts
- Adds a program format with a clear length for each card. Day counts are easy to read.
#6
DIVERSE WORKOUTS
- workoutsnot in name
- What it shows
- A workouts list with weight loss routines such as Belly Fat Burner HIIT (beginner, 7 mins) and a bodyweight workout row, with small thumbnails.
- Why it converts
- Shows breadth of content with level and time on each row. “Diverse” is a vague word.
Icon and design system
What makes the page read as one brand at a glance.
- One symbol, a slanted letter G, on a green background. It is simple, but the letter says nothing about workouts.
- Green matches the highlight color of the captions, so icon and gallery look like one brand.
- No fine detail, so it should hold up at small sizes.
- 01
Two-tone captions
A white first line and a bright green second line in bold capitals.
- 02
Result first, product second
The first image shows the body result the app talks about. App screens start from the next image.
- 03
One dark green system
A dark green background, a caption block at the top and dark cards repeat on most images. Swiping reads as one story.
- 04
Body photos beside real UI
Photos of bodies sit next to plan cards, lists and exercise drawings, so the visitor sees both the goal and the tool.
- 05
Level and time on many cards
Cards print a level or a length, such as Intermediate · 20 Mins or 28 DAYS. A visitor can judge fit at a glance.

Where the points are
- Ask happy users for a rating+12 pts
4.7 stars from 178 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: lose weight, gain muscle, personalized plans, target area, fitness challenge, workouts. 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.
- Open with the outcome your user wants, in one large line.
- Show a real app screen in the second image, not only photos.
- Keep one caption style, one background and one accent color across the set.
- Print level, length or count on UI cards so the value is readable.
- Pick specific caption words. Name the use case instead of a word like “diverse”.
- If you show a badge, make sure it is true and say where it comes from.
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 “Gymax: Muscle Workout Planner”, which uses 29. 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. Gymax uses them for lose weight and personalized plans.
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. Gymax 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.
- Gymax: Muscle Workout Planner 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.
