App Store category: primary vs secondary, what each one affects, and what top apps choose
Two dropdowns in App Store Connect that decide where your app is browsed, which charts it competes in, and — since 2026 — whether you owe Apple a medical device declaration.
Checked against Apple's categories, search and discoverability guides, App Store Connect Help, the App Review Guidelines, Apple Developer News (Mar 26, 2026), and iTunes Search API results for eight searches, on Oct 11, 2026.
Definition
- App Store category
- An App Store category is one of Apple's subject groupings, such as Health & Fitness or Productivity. Each app picks a primary and an optional secondary category; Apple indexes both for search, and the primary decides where the app is browsed and charted.
Also called: Primary category · Secondary category · App category
The short answer
Every App Store app has a primary category and can add a secondary one. Apple says both are indexed by its search algorithm, while the primary decides where the app appears when people browse or filter search and which tab it sits on. Pick the category that describes the app's main function, add a relevant secondary, and remember that changing either needs a new version.

01What your category does
Your primary category and optional secondary category are indexed by our search algorithm. For games, you can select the Games category as the primary or secondary category and you can select up to two additional subcategories to better define your game.
| Primary category | Secondary category | |
|---|---|---|
| Indexed for search | Yes | Yes |
| Where people browse and filter search | Yes — “the category in which the app appears” | Not stated by Apple |
| Apps tab or Games tab placement | Decides it | No |
| Required | Yes | Optional |
| Triggers the medical device declaration | If Health & Fitness or Medical | If Health & Fitness or Medical |
Apple's categories guide calls the primary category “important for your app's discoverability” and says it should be “the one that best describes the main function or subject matter of your app.” Because the category is already indexed, Apple also tells you not to repeat words from it in your keyword field — see our keywords field playbook.
According to ASOitis's check of 71 top App Store results across eight common searches on October 11, 2026, 60 apps set a secondary category and 40 list Health & Fitness or Medical as one of their two — including five of nine habit trackers that file under Productivity first — which makes all 40 subject to Apple's regulated medical device declaration.
02What top apps actually choose
We pulled the top results for eight common searches from Apple's iTunes Search API (US) on October 11, 2026 — 71 apps — and read their categories:
| Search | Most common primary | Most common secondary |
|---|---|---|
| budget | Finance (9 of 9) | Productivity (8) |
| calorie tracker | Health & Fitness (8 of 8) | Food & Drink (4) |
| habit tracker | Productivity (8 of 9) | Health & Fitness (4) |
| language learning | Education (9 of 9) | Travel (5) |
| meditation | Health & Fitness (9 of 9) | Lifestyle (6) |
| photo editor | Photo & Video (9 of 9) | Graphics & Design (4) |
| sleep tracker | Health & Fitness (7 of 9) | Lifestyle (3) |
| workout | Health & Fitness (9 of 9) | Lifestyle (4) |
Two patterns stand out. Competitors in a niche almost always agree on the primary category — fighting the consensus puts you in a different browse list from everyone your users compare you with. And the secondary is where they differ: habit trackers mostly file under Productivity and add Health & Fitness second, while language apps lean on Travel. Sixty of the 71 apps set a secondary at all.
03Apple's rules
- Pick honestly. Guideline 2.3.5: “Select the most appropriate category for your app… If you're way off base, we may change the category for you.” Our Guideline 2.3 page covers metadata rejections.
- Changing needs a version. Apple's list of properties you can edit “at any time without submitting a new version” doesn't include the primary or secondary category.
- Games get subcategories. If you choose Games, you can add up to two subcategories such as puzzle or strategy.
- Kids is one-way. Once an app marked Made for Kids is approved, Apple says “this selection cannot be changed and all subsequent updates will need to follow the Kids category guidelines.”
- Health & Fitness and Medical carry an obligation. Since March 26, 2026, apps with either as their primary or secondary category must declare regulated medical device status in the EEA, UK and US; existing apps by early 2027 — see Guideline 1.4.1.
Frequently asked questions
Does the App Store category affect search ranking?
Apple says your primary and optional secondary category are indexed by its search algorithm, and lists the primary category among the text-relevance factors for search results. Choose a category that matches what people search for your app to do.
What's the difference between primary and secondary category?
Both are indexed for search. The primary category also decides where your app appears when people browse or filter search results and whether it sits on the Apps or Games tab. The secondary is optional.
Can I change my app's category without an update?
No. Apple's list of App Store Connect properties you can edit at any time doesn't include the primary or secondary category, so change them when you submit a new version.
How many categories can an App Store app have?
Two: a primary and an optional secondary category. Games can also choose up to two Games subcategories.
Which category should a habit tracker choose?
In our October 2026 check, eight of the nine top habit tracker results used Productivity as their primary category, and four added Health & Fitness as secondary. Note that a Health & Fitness category in either slot means declaring medical device status.
