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
Meet your personal health companion
- health companionnot in name
- What it shows
- A close-up photo of a person with eyes closed smelling a yellow flower against a blue sky, with the Juno name, “Trusted by 250,000+ happy users” and a Forbes logo.
- Why it converts
- Sets a calm mood and puts the trust badges up front, but it does not show the app in use. A visitor learns the tone, not what Juno does. “Health companion” is also a broad phrase.
#2In search results
Track symptoms just by texting
- track symptomsnot in name
- What it shows
- A chat where a user writes “I have an awful migraine.” and a mascot replies that it logged it, above a day-by-day symptom chart.
- Why it converts
- Shows the input method and the result in one frame: type a message, get a log. The caption names the task in plain words.
#3In search results
Come ready for your appointment
- symptom reportnot in name
- What it shows
- A date-range picker and a “Your symptom report” card listing a summary, trend charts and tables for symptoms, meds, triggers and notes.
- Why it converts
- Ties the app to a real moment in the user's week, the visit. The card lists what the report contains, so the benefit is concrete.
#4
Make flare days more manageable
- flarenot in name
- What it shows
- An energy screen with a battery reading “88% left”, a spoons-used count and a plan with shower and cook meal entries.
- Why it converts
- Speaks in the words of people who live with the condition. The battery is easy to read at a glance, though the caption states an outcome without saying how the app gets there.
#5
Never forget a dose again
- dosenot in name
- What it shows
- A medication list with “Meds taken 2/3”, a progress bar, the next dose time and entries marked taken or due.
- Why it converts
- A clear benefit in one short line, backed by a screen that shows what is done and what is next.
#6
Understand your triggers
- triggersnot in name
- What it shows
- Health, sleep and calendar icons feeding into sleep, morning coffee and headache entries, ending in a card reading “Headaches often followed morning coffee”.
- Why it converts
- Shows how the app turns logged data into an insight a visitor can picture. It is a diagram, not a plain app screen, so some labels are small.
Icon and design system
What makes the page read as one brand at a glance.
- One friendly character is the single focus, so the icon reads as a companion rather than a medical tool.
- The blue sky background matches the sky in the screenshots, so icon and gallery look like one brand.
- No text and a simple background, so it should stay recognizable at small sizes. Its 3D style differs from the flat app screens.
- 01
Trust badges before the product
The first image carries a user count and a Forbes logo, before any app screen appears.
- 02
Benefit caption, then proof screen
Most captions state a result such as “Never forget a dose again”. Below, a phone shows the screen that delivers it.
- 03
A shared sky and caption style
Most images use a blue sky background, a large white bold caption at the top and a centered phone. The set reads as one story.
- 04
Words the audience uses
“Flare days”, “symptoms”, “triggers” and “dose” are terms people with a long-term condition already use.
- 05
Cards break out of the phone
The report card and the symptom chart extend past the device frame.

Where the points are
- Ask happy users for a rating+5 pts
4.8 stars from 10,748 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: health companion, track symptoms, symptom report, flare, dose, triggers. 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 app in use in the first image, not only a mood photo.
- Put a trust signal where visitors see it first, and make it specific.
- Write each caption as a result the user wants, in a few words.
- Use the exact words your audience uses for their problem.
- Pair each caption with the one screen that proves it.
- Keep one background, one caption style and one icon color family across the set.
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 “Juno: Chronic Illness Support”, 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. Juno uses them for health companion, track symptoms and symptom report.
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. Juno 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.
- Juno: Chronic Illness Support 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.
