Screenshots and why they convert
6 screenshots of up to 10. The first 3 show in search results when there's no preview video.
#1In search results
Auto-remove Handwriting
- handwritingnot in name
- What it shows
- A crumpled, marked-up test paper being scanned, with a scan line across it and Crop, Rotate, Eraser and Delete tools below.
- Why it converts
- Opens on a distinctive feature, not a generic scan. The caption names that feature in two words, and the big type is readable at search-result size.
#2In search results
Print & Share In PDF/JPG
- pdfnot in name
- printnot in name
- What it shows
- An export sheet with PDF and JPEG tabs, a page preview, share buttons and PDF and JPG file badges floating outside the phone.
- Why it converts
- Shows what happens after the scan: a file you can send or print. The caption names two formats people look for.
#3In search results
Learn From Mistakes
- mistakesnot in name
- What it shows
- A test paper with three questions marked with red X icons, and green and pink labels reading “Categorized by subject” and “Create your own test”.
- Why it converts
- Moves from a one-off scan to a study habit. The labels point at two features without making the viewer read the app UI.
#4
Efficient Study Materials
- study materialsnot in name
- What it shows
- A list of saved test papers with green, yellow and pink labels for exam types, and a cartoon teacher in the corner.
- Why it converts
- Speaks to students preparing for exams. The caption is broad, and the labels carry the specific use cases.
#5
Scan & Solve Homework
- homeworkin name
- solvenot in name
- What it shows
- A phone camera view of handwritten equations with a box around one, and a robot mascot with a green “AI-powered” label.
- Why it converts
- Names the main use in the app's own title words. The AI label adds a reason to try it. This is the fifth image, so a visitor who stops early may not see it.
#6
Step-by-step Explanation
- explanationnot in name
- What it shows
- A chat screen with a photographed equation and a written answer broken into steps, plus the robot mascot.
- Why it converts
- Shows the output of a solve, so the visitor sees what they get.
Icon and design system
What makes the page read as one brand at a glance.
- One idea: a scanned paper with a grade on it. It says “scan homework” without text.
- Blue background matches the blue headers in the screenshots, so icon and gallery look like one brand.
- Simple shapes and no text, so it stays clear at small sizes.
- 01
Big two-line captions
White bold type on a blue curve at the top of most images. The text is large, so it reads when the image is small.
- 02
Colored labels float over the phone
Green, pink and yellow labels sit on top of the screen to name features.
- 03
Mascots add a friendly tone
A cartoon student, a teacher and a robot appear across the set. They suit a young study audience.
- 04
One shared layout
Most images share a blue header, a phone frame and a caption position. The set reads as one story.
- 05
The headline use comes after the features
“Scan & Solve Homework”, the use in the app's title, is the fifth image. The first image shows a handwriting-removal feature.

Where the points are
- Ship an update+15 pts
The last update was 204 days ago. A new version also refreshes the "What's New" notes people read before they download.
- Ask happy users for a rating+12 pts
4.7 stars from 245 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.
- Use the rest of the app name+2 pts
5 characters are free. Add the next most important search term.
- Check caption terms against your subtitle and keywords
7 caption terms aren't in the app name: handwriting, pdf, print, mistakes, study materials, solve, explanation. 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.
- Put the use named in your title in the first screenshot.
- Keep captions to two short lines in large type.
- Use colored labels to point at features instead of asking people to read the UI.
- Show the result of the task, not only the input screen.
- If you show text in a phone, make it large enough to read at thumbnail size.
- Add a rating, award or user count if you have a real one. A first image can carry it.
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 “GradeUp: Homework Scanner”, which uses 25. 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. GradeUp uses them for handwriting, pdf and mistakes.
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. GradeUp uses 6.
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.
- GradeUp: Homework Scanner 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.
