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
STRONGER, BIGGER, FITTER
- What it shows
- A dark, close-up photo of a shirtless, muscular man, with the Calisteniapp logo and a “+3M ATHLETES” laurel badge at the top. No app screen is shown.
- Why it converts
- Leads with the result a visitor wants, in a big headline. The photo alone does not say what the app does or that it is about calisthenics, so the visitor has to guess. The user-count badge is the app's own claim.
#2In search results
PROGRAMS FOR EVERY GOAL
- programsnot in name
- What it shows
- A phone showing a “Fullbody circuit” card (Easy) and an “EVO Routine” row with “Core at home” and “Core at the park”. A small line below the headline lists goals: gain strength, lose fat, build muscle.
- Why it converts
- First screen that shows the product. The headline names plans and the small line lists three goals, so different visitors can find theirs. The goal line is small gray text and may not read in search results.
#3In search results
STEP-BY-STEP GUIDED TRAINING
- guided trainingnot in name
- What it shows
- A “Your first pull-up” program screen: 7 phases, “Phase 1, Novice stage level 0”, 1/3 weeks, and a Session A card for today.
- Why it converts
- Shows a beginner path with a concrete first goal. A visitor who cannot do a pull-up yet can see that the app starts from zero. This is a feature people look for.
#4
TRACK AND MEASURE YOUR PROGRESS
- progressnot in name
- What it shows
- A stats screen with an achievements row, “Unlocked exercises 78 / 703”, a 7 Days / 30 Days / Total summary (0.63 hours, 1 session, 70.6 energy) and the start of a muscle map.
- Why it converts
- Speaks to the wish to see progress over time. The screen has many small numbers and labels, so it is hard to read at thumbnail size. Only the headline carries the message there.
#5
LEARN CALISTHENICS SKILLS
- calisthenicsnot in name
- What it shows
- Two program cards, “Front lever strength” and “Backlever”, each with a photo, a difficulty level and muscle groups.
- Why it converts
- First place the word “calisthenics” appears in a headline, matching the app's name. Named skills like front lever are specific terms that fans of the sport know.
#6
FIND THE PERFECT WORKOUT FOR YOU
- workoutnot in name
- What it shows
- A “Back and biceps muscle building” workout screen with 36 exercises, pull-up bar, 32 mins, and a list of exercises with sets and reps.
- Why it converts
- Shows what a single workout looks like: equipment, time and exercises. The headline is a general promise, so this image works more as proof of detail than as a new reason to download.
Icon and design system
What makes the page read as one brand at a glance.
- One mark, the “CA” letters with a star cut, on a plain dark background. No photo and no UI.
- The orange on black matches the headline and accent colors in the screenshots, so icon and gallery look like one brand.
- The letters are not a picture of a workout, so the icon does not say what the app does. The name has to do that.
- 01
Photo first, screens after
The first image is a large photo and a short headline. The images after it put a phone with a real app screen under a headline and a gray line.
- 02
Headline plus a gray line
Most images have a bold white headline and a gray sentence below it. The headline carries the message at small size. The gray line adds detail that may be too small to read in search results.
- 03
One dark system with orange
Most images use a black background, an orange glow and the same type. The look matches the icon, so the gallery reads as one set.
- 04
A user count on the first image
“+3M ATHLETES” sits in a laurel badge at the top of the first image. It is the app's own claim, shown where search results show it.
- 05
Goals, path, progress, skills
The images cover programs by goal, a guided path, progress tracking, named skills and single workouts. Together they answer what a visitor gets after install.

Where the points are
- Ask happy users for a rating+9 pts
4.8 stars from 1,661 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
5 caption terms aren't in the app name: programs, guided training, progress, calisthenics, workout. 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 what the app does in the first image, not only the feeling you want to give.
- If you open with a photo, add one line or a screen that names the activity.
- Put the words your users use, such as the sport or the skill, in a headline.
- Keep the main message in the big headline. Treat small gray lines as extra.
- Use one background, one type style and one accent color across all images, and match the icon.
- Show a concrete first step, like a beginner program, so new users see a way in.
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 “Calisteniapp: Fit & Strong”, which uses 26. 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. Calisteniapp uses them for programs and guided training.
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. Calisteniapp 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.
- Calisteniapp: Fit & Strong 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.
