Screenshots and why they convert
7 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
Anywhere Anytime
- What it shows
- Two large mushroom photos with name labels (“Panaeolus”, “Bolete”) over a blurred forest, with a phone edge and a hand at the bottom.
- Why it converts
- The name labels hint at identification, and the forest sets the topic. But the caption says nothing about what the app does, and no app screen is visible. A visitor has to guess the feature.
#2In search results
Get Mushroom ID with a quick photo
- mushroom idnot in name
- What it shows
- A result screen for King bolete with a circular photo, alternate names, the scientific name, a notice, and a warning about a similar toxic species. A pink fork-and-spoon badge sits at the top right.
- Why it converts
- This is the first image that states the job: take a photo, get a mushroom ID. The caption names a phrase people look for. It answers “what does this app do”.
#3In search results
Be aware of toxic mushrooms
- toxic mushroomsnot in name
- What it shows
- A Fly agaric result screen with a pop-up card headed “Lethal” and a warning icon, saying the mushroom is highly toxic.
- Why it converts
- Shows a second benefit, warnings about toxic species, as a concrete screen. A visitor can see the app flags risk, not only names. The app's own text carries the claim.
#4
Mushroom identification guides
- mushroom identificationnot in name
- What it shows
- An article screen with two photos of fly agaric and a short paragraph describing it.
- Why it converts
- Tells visitors there is reading content beyond the photo scan. The screen is mostly photos and a paragraph, so the caption carries the message. The paragraph is too small to read in search results.
#5
Consult with mushroom experts
- mushroom expertsnot in name
- What it shows
- A chat screen. A user asks where to find morels, and a long pink reply lists seasons and trees. A second question about a dog is partly visible below.
- Why it converts
- Shows a human-help feature in a familiar chat layout, which is easy to grasp. The long reply is dense text, and the caption does the selling.
#6
Save your mushroom collection
- mushroom collectionnot in name
- What it shows
- A saved-collection list with photos, names, places and dates, a search box, and a “Subscribe Now” button at the top.
- Why it converts
- Gives a reason to keep using the app after the first ID. The visible subscribe button tells visitors early that part of the app is paid.
Icon and design system
What makes the page read as one brand at a glance.
- One symbol, a spotted mushroom, names the topic at once.
- The scan corners around it hint at pointing a camera, which fits the photo-ID job.
- No text and little detail, so it should hold up at small sizes. The red matches the pink-red accents inside the screenshots.
- 01
Big dark captions on a pale green field
Bold dark text sits on a flat light green background. Most captions are two short lines that stay readable when the image is small.
- 02
Captions name what users look for
“Mushroom ID”, “toxic mushrooms”, “identification guides” and “mushroom experts” are terms a mushroom hobbyist might use. Most captions name one.
- 03
One feature per screenshot after the first
ID by photo, toxic warnings, guides, expert chat and a saved collection each get their own image. The order moves from the main job to extras.
- 04
The first image is a mood shot
It opens with large photos and a slogan, while the explicit job statement comes second. A visitor who sees only the first image gets a topic, not a feature.
- 05
Real screens with the key message in the caption
Most images show real app UI in a phone frame. Much of the on-screen text is small, so the caption does the work in search results.

Where the points are
- Ship an update+15 pts
The last update was 371 days ago. A new version also refreshes the "What's New" notes people read before they download.
- Ask happy users for a rating+5 pts
4.7 stars from 24,686 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: mushroom id, toxic mushrooms, mushroom identification, mushroom experts, mushroom collection. 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.
- Make the first image say what the app does, not only what it is about.
- Avoid a slogan like “Anywhere Anytime” as the lead caption. Name the job instead.
- Write captions in the words your users use.
- Give each screenshot one benefit and one short two-line caption.
- Use a flat, high-contrast background so captions read at thumbnail size.
- Put the main job before extras such as guides and saved lists.
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 “Picture Mushroom: Identifier”, 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. Picture Mushroom uses them for mushroom id and toxic mushrooms.
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. Picture Mushroom uses 7.
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.
- Picture Mushroom: Identifier on the App Store
