#1In search results
The new way of instrument learning
- instrument learningnot in name
- What it shows
- A person playing a saxophone beside a phone showing sheet music with a green note bar, and a “Music Apps We Love” App Store badge at the bottom.
- Why it converts
- Shows a real player beside a phone with notation. The caption itself is a general claim (“the new way”). The badge is the app's own printed claim.
#2In search results
Choose from 12+ instruments
- instrumentsnot in name
- What it shows
- A violin player and a piano player, with a phone showing notes and a large green check mark between them.
- Why it converts
- Gives a concrete number of choices, which is more specific than a slogan. Two instruments in one frame hint at range without a list.
#3In search results
Play your favourite songs with backing tracks
- backing tracksnot in name
- songsnot in name
- What it shows
- A song list with cover art for “For Elise” and “Swan Lake”, a Your Favorites list, and Easy and Medium labels.
- Why it converts
- Shows the song library, a reason to play that is not a drill. “Backing tracks” is a term some learners look for. The difficulty labels show that songs are sorted by level.
#4
Learn step-by-step with guided lessons
- guided lessonsnot in name
- What it shows
- A video lesson of a saxophone player with a play button, and scrolling notation with green and red note marks below it.
- Why it converts
- Shows a teacher on video next to the notes, so the visitor sees how a lesson works. “Step-by-step” speaks to beginners.
#5
Improve with instant feedback on every note
- instant feedbacknot in name
- What it shows
- Lines of sheet music with notes marked green or red, a moving cursor line and a green check mark.
- Why it converts
- Shows the feedback loop itself: right and wrong notes are marked as you play.
#6
From beginner to pro: Lessons for everyone
- lessonsin name
- What it shows
- A “Learn the Essentials” lesson list with video items, check marks on finished ones, and a purple “Get ready for your first song” bar with a play button.
- Why it converts
- Shows a path with progress marks, so a visitor sees there is more to do after the first lesson. “Beginner to pro” is a broad claim, so the list does the proving.
Icon and design system
What makes the page read as one brand at a glance.
- One shape combines a play button and a music note, so it says “music” and “video” together.
- Flat purple background, no text and no small detail, so it stays clear at small sizes.
- The same purple is the highlight color in every screenshot caption, so icon and gallery look like one brand.
- 01
Two-tone captions
Dark navy text with the key phrase in bright purple. The purple words are the ones the eye lands on.
- 02
Mostly one idea per screenshot
Instruments, songs, lessons and feedback each get their own image, so most captions make a single point.
- 03
Real players and real screens
Photos of people with instruments sit next to actual app screens. The visitor sees both the activity and the tool.
- 04
Same lilac background
Most images use the same purple background and a phone frame. Swiping reads as one story.
- 05
A badge on the first image
A “Music Apps We Love” App Store badge sits at the bottom of screenshot 1. It is the app's own printed claim.

Where the points are
- Ask happy users for a rating+16 pts
4.4 stars from 2,384 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
6 characters are free. Add the next most important search term.
- Check caption terms against your subtitle and keywords
6 caption terms aren't in the app name: instrument learning, instruments, backing tracks, songs, guided lessons, instant feedback. 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 caption say what the app does, not only that it is new.
- Put a real person using the product next to a real app screen.
- Use a specific number or label, like “12+ instruments”, in place of a general promise.
- Show the feedback or result screen, not only menus and lists.
- Pick one highlight color and use it in the icon and in every caption.
- Add a trust badge only if it is real, and place it where it is seen early.
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 “tonestro - Music Lessons”, which uses 24. 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. tonestro uses them for instrument learning, instruments and backing tracks.
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. tonestro 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.
- tonestro - Music Lessons 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.
