A Health & Fitness app's App Store page, taken apart: the screenshots and why each one helps people decide to download, the icon and design system, and an ASO score out of 100.

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
Workouts & nutrition for faster results
- workoutsnot in name
- nutritionnot in name
- What it shows
- A woman holding a dumbbell on a red background, the app icon above the caption, a “97,6% users would recommend it to others” badge and a five-star review that mentions losing 10 kg.
- Why it converts
- Names both halves of the offer, workouts and nutrition, in the first frame. The recommend badge and the quoted review give a reason to trust it early, though they are the app's own printed claims.
#2In search results
Train with a plan tailored to you
- workout plannot in name
- What it shows
- A tilted phone showing the Workouts tab: program filters, a featured “Start Strong At Home” program with its length, days and minutes per session, and more programs below.
- Why it converts
- Turns “plan” into something visible: programs with weeks, days and session time. A visitor can see what they would pick from.
#3In search results
Master proper technique
- techniquenot in name
- What it shows
- A person doing a banded squat inside a phone-shaped outline, with a small round video-call style portrait and a speech bubble: “Remember, keep your abs tight and your back straight”.
- Why it converts
- Shows guidance during a workout, not just a list of exercises. The spoken-tip bubble makes the coaching idea easy to grasp without reading the app UI.
#4
Track the meals you’ve eaten and the activities you’ve completed
- track mealsnot in name
- activitiesnot in name
- What it shows
- A Daily tracker screen with eaten, burned and left-to-eat calories, protein, fat and carb bars, and a log of meals and a bike ride. Food photos and a macros card sit around the phone.
- Why it converts
- Shows the nutrition side as a working screen with real-looking entries.
#5
Calorie calculator records your meals outside the app
- calorie calculatornot in name
- What it shows
- A phone camera view of a bowl of ramen with an “AI” tag, a “New feature” label on top, and three input icons: text or voice, photo, barcode.
- Why it converts
- Says how logging works: three ways to enter food. The “new feature” label flags something fresh to returning visitors, and the ramen photo shows the result at a glance.
#6
Build strength foundations
- strengthnot in name
- What it shows
- A woman holding a barbell on a blue background, with labels “HIIT”, “3-phase hybrid system”, “HIRD” and weight percentages 60%, 70%, 80%, 95%. Program cards run along the bottom.
- Why it converts
- Adds a training-method angle for people who want strength work. The labels are small and the terms are not explained, so a newcomer may not know what they mean.
Icon and design system
What makes the page read as one brand at a glance.
- One illustrated figure on a plain coral background, with no text. It points to fitness without a word.
- The coral red matches the red backgrounds and caption accents in the gallery, so icon and screenshots share one color.
- The drawn style differs from the photos in the screenshots, which show real people. The icon also does not hint at the nutrition half of the offer.
- 01
Both halves of the offer up front
The first caption says “Workouts & nutrition”. Later images split into training (plans, technique, strength) and food (tracker, calorie calculator), so each visitor finds their reason.
- 02
Printed proof in the first frame
A “97,6% users would recommend it to others” badge and a five-star review sit on the first image. They are the app's own claims, placed where search results show them.
- 03
People as the main subject
Real people lead several images, and the phone UI is shown on the others. The photos carry the mood, the UI carries the detail.
- 04
Short caps captions, then a second line
White bold capitals, sometimes in two sizes. The top line reads at small size.
- 05
Labels that flag what is new
A “New feature” tag and a row of three input icons (text or voice, photo, barcode) explain a feature in one look.

Where the points are
- Use the rest of the app name+18 pts
8 characters are free. Add the next most important search term.
- Ask happy users for a rating+14 pts
4.6 stars from 392 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
8 caption terms aren't in the app name: workouts, nutrition, workout plan, technique, track meals, activities, calorie calculator, strength. 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 your two or three main offers in the first caption.
- Put a rating, user share or review on image one if you have a real one.
- Show a plan or a result as a screen, not only as a promise.
- Write one idea per caption and keep the main line large.
- Mark a new feature with a short label so returning visitors notice it.
- Use the icon color as the accent color across your 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. 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. Diet & Training by Ann uses them for workouts, workout plan and technique.
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. Diet & Training by Ann 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.
