- anxietynot in name
- What it shows

- Shows the product on the wrist in the first frame, so a visitor sees what it measures and where. “Stress” and “anxiety” are words people look for. The region badge is the app's own claim.

Visual Charts with Clear Explanations · Uncover Your Stress Patterns
- stressin name
- What it shows
- A tilted phone with a green face, “Excellent” and a latest HRV of 62 ms, below an “Essential Apple Watch App” badge. The phone runs off the bottom edge.
- Why it converts
- Says there is a phone app with charts and written explanations, not only a watch face.
#3In search results
- What it shows
- A Stress Trend line chart, an HRV Trend bar chart and a year-view Daily Overview grid of colored dots, with a tilted phone showing a 62 ms reading across the corner.
- Why it converts
- A visual preview of the trend views the previous caption promised. With no caption, a visitor has to work out what each chart means from the images alone.
#4
Bio Age, at a glance
- bio agenot in name
- What it shows
- A Body Age screen: 38.3, a red tag “3.5 yrs older”, an aging pace scale and a list of influencing factors with VO2 Max, resting heart rate and HRV.
- Why it converts
- Adds a different reason to install: a single number about yourself. A curiosity hook like this gives a visitor a reason beyond the watch face.
#5
Understand Your Heart Rate at a Glance
- heart ratenot in name
- hrvin name
- What it shows
- Cards on a pink background: time period statistics, a “Pressure trend” line chart, top overload and max HRV tiles, and a daily bar chart with sleep, walking and sitting markers.
- Why it converts
- “Heart rate” and “HRV” are named terms people look for. The caption sits under an “App Store” line with a laurel.
#6
See your style at a glance
- watch facesnot in name
- What it shows
- Several Apple Watch faces and complications with the time, HRV, steps and other rings, in different layouts, on a pale lavender background.
- Why it converts
- Shows that the watch face can be customized. It speaks to people who choose apps by how they look on the wrist.
Icon and design system
What makes the page read as one brand at a glance.
- One symbol, a heart with a smile, suggests a calm health app before the name is read.
- The mint green matches the color of the face and charts in the screenshots, so icon and gallery share one look.
- No text and little detail, so it should hold up at small sizes.
- 01
A character carries the brand
The smiling green face from the icon appears on the watch, on the phone and in the chart corner. It links the pages to the icon.
- 02
Printed claims at the top
Laurel badges sit above most captions: “Chosen by users worldwide in 170+ regions”, “Essential Apple Watch App”, and an App Store line. They are the app's own claims.
- 03
Tinted backgrounds across the set
Mint, pale blue, pink and lavender backgrounds change from image to image. The caption layout and type stay mostly the same, so the set still reads as one system.
- 04
Real UI with numbers and charts
Most images show actual screens: an HRV reading, trend charts, a body age score. The product is the visual.
- 05
Caption plus a subline
A bold headline sits over a gray subline that adds detail.

Where the points are
- Ask happy users for a rating+21 pts
4.2 stars from 579 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
4 caption terms aren't in the app name: anxiety, bio age, heart rate, watch faces. 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 the device or screen where the core number appears in the first image.
- Name the problem in the first caption, in the words your users use.
- Put a caption on every image, so a chart is never left to explain itself.
- Keep the headline short enough to read at search-result size. Move detail to a subline.
- Use a recurring character or shape from the icon in your screenshots.
- Print a trust claim only if it is true and you can show 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 “RelaxWatch: Stress&HRV Tracker”, which uses 30. 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. RelaxWatch uses them for stress and stress.
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. RelaxWatch 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.
- RelaxWatch: Stress&HRV Tracker 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.
