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
TRAIN WITH PRECIS
- What it shows
- Two gold laurel badges, “2026 Best app” and “500M Workout logged”, above a large white headline on blue. The phone is mostly cropped off the right edge.
- Why it converts
- Puts printed proof first: the badges are the app's own claims. The headline is large, but the phone is barely visible, so this frame says little about what the app does.
#2In search results
ION
- What it shows
- The end of the headline, “ION”, and a phone showing an Incline Dumbbell Curl screen with a body illustration and a timer. A smartwatch beside it shows a rest-time notice.
- Why it converts
- Shows the app in use: an exercise screen with a timer, plus a watch. The headline runs across two images, so this one only makes sense next to the first.
#3In search results
Science-Driven Training Personalized for You
- What it shows
- Two lines of white text, a sparkle icon, and a quoted request: “Build a full body routine with kettlebells”. Below it are body-part tiles and equipment tiles (dumbbells, mat, kettlebell).
- Why it converts
- Shows the input as plain language and the options as tiles, which explains personalization in one glance. “Science-Driven” is the app's own claim, and nothing on the image shows its source.
#4
Muscle Group Analysis
- muscle groupnot in name
- What it shows
- A body outline with percentages per muscle group, some highlighted in green, and a weekly volume bar chart at the bottom.
- Why it converts
- The caption names a feature people look for. The body map with green highlights turns the data into one picture.
#5
Programs by Pros & Trainers
- programsnot in name
- What it shows
- A video thumbnail with a play button, a row of Day 1 to Day 3 tabs, and an exercise list (Squat, Bench press, Deadlift, 5 sets each) with a start button.
- Why it converts
- Shows ready-made plans with a clear daily structure, so a visitor who does not want to build a routine sees an option. The video suggests coaching content. The start button label is in Korean on this English image.
#6
Scan Equipment Learn Instantly
- equipmentnot in name
- What it shows
- A camera view of a gym machine with a scan frame and a “‘Lat pulldown’ Detected” label, with a small exercise illustration below it.
- Why it converts
- Shows a feature that fits the gym setting: point the camera at a machine and get its name. The camera view is real and easy to read, and the caption states the benefit in four words.
Icon and design system
What makes the page read as one brand at a glance.
- One idea, a face and a flexed arm, hints at strength training without text.
- Flat illustration on a plain blue field, with no photo or UI copy.
- Blue matches the background of the first screenshots, so icon and gallery share one color.
- 01
Proof badges first
Gold laurel badges lead the gallery: “2026 Best app” and “500M Workout logged”. Both are the app's own printed claims.
- 02
A headline that spans two images
“TRAIN WITH PRECISION” runs across the first two images, so swiping reads as one scene. The cost is that the first image alone is cut off.
- 03
Blue first, then dark
The opening images use a blue background. The later ones switch to charcoal with a large white title above one phone. The type and phone placement stay similar.
- 04
Short feature titles
Later captions are two short lines naming one feature each: muscle group analysis, programs, equipment scan. Each is a term a gym user might use.
- 05
Real-use scenes
The images show a timer, a watch notice, a camera scan in a gym and a daily plan. Each is a moment of use, not only a screen layout.

Where the points are
- Ask happy users for a rating+10 pts
4.9 stars from 266 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
3 caption terms aren't in the app name: muscle group, programs, equipment. 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 frame, not only badges or a slogan.
- If you use a proof badge, print a claim you can back up.
- Do not cut a key headline across images unless the first image still works alone.
- Name one feature per caption, in the words your users use.
- Match the icon color to the first screenshot background.
- Keep the type and phone placement fixed when you change background colors.
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 “Gymwork: Workout Tracker Log”, which uses 28. 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.
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. Gymwork 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.
- Gymwork: Workout Tracker Log 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.
