App Store Category Rankings: How to Pick the Right Category and Sub-Category

App Store Category Rankings: How to Pick the Right Category and Sub-Category

Category selection is one of the most consequential decisions you make when submitting an app — and most indie developers treat it as an afterthought. They pick the most obvious category, submit, and wonder why their "Top Charts" ranking is stuck in triple digits.

Here's how to choose a category strategically, not reflexively.

Why Category Matters More Than Most Developers Think

Category affects three things simultaneously:

1. Browse visibility. The App Store's browse surface — Top Free, Top Paid, Top Grossing — is organized by category. Users browsing categories see the top apps in that specific list, not the global chart.

2. Algorithmic context. Apple's and Google's search algorithms use category as a relevance signal. An app in "Health & Fitness" ranking for "meditation" is algorithmically different from the same app in "Lifestyle."

3. Competitor density. Some categories are dominated by billion-dollar companies. Others have surprisingly weak competition at the top 50 level. Your ranking potential depends heavily on who you're competing against.

The Primary Category Decision

On both App Store and Google Play, you choose one primary category. This is what determines your placement on category browse charts and the primary competitive set Apple/Google compares you to.

The mistake most developers make: choosing the category that most accurately describes the app rather than the category where they have the best chance of ranking.

These are not the same thing.

A mindfulness journaling app could legitimately belong in:

• Health & Fitness
• Lifestyle
• Education
• Productivity

In the App Store, "Health & Fitness" is dominated by Calm, Headspace, MyFitnessPal, and Nike — apps spending millions on UA. "Lifestyle" has a significantly weaker top 50. "Education" is weaker still.

Same app, completely different competitive landscape depending on category.

How to Evaluate Category Competitiveness

For each candidate category, check:

Top 10 ratings count. Open the App Store, browse that category's Top Free chart, and look at the rating counts for the #10 and #25 apps. If #25 has 50,000+ ratings, this is a saturated category. If #25 has 3,000 ratings, there's room for an indie app to break in.

Update recency of mid-tier apps. Scroll to positions 50-100 on the chart. When were those apps last updated? Stale apps in the mid-tier indicate low competition — fresh, well-maintained apps can climb past them.

Keyword overlap. Search your primary keywords in the App Store. Do the results come from one category or multiple? If results are mixed across categories, your target keywords aren't strongly owned by one category — giving you flexibility.

iOS Secondary Category: The Overlooked Lever

On iOS, you can set a secondary category. This is underused. Your app appears in browse charts for both categories.

The strategic play: put your primary category as the one you want most visibility in, and your secondary as the least competitive adjacent category where your app qualifies.

A recipe app could be:

• Primary: Food & Drink (obvious, but very competitive)
• Secondary: Health & Fitness (competitive, but different audience)

Or:

• Primary: Lifestyle (less competitive)
• Secondary: Food & Drink (more competitive, but you get chart presence there too)

Test both configurations over 60-day periods and compare organic install rates.

Google Play: Primary and Secondary Categories

Google Play's system works slightly differently. You choose a primary category (called "Application Type" + "Category"), and Google uses behavioral signals to additionally associate your app with related categories over time.

This means your initial choice matters less than on iOS — Google can recategorize you based on user behavior and search patterns. But your starting category still determines your initial chart placement, so apply the same competitive analysis logic.

---

Sub-Categories on Google Play

Google Play has more granular sub-categories than iOS. "Health & Fitness" splits into "Exercise & Fitness," "Diet & Nutrition," "Meditation," "Sleep," and several others.

Sub-category charts are smaller and much easier to rank in than the parent category. A meditation app ranking #3 in "Meditation" sub-category gets visible placement in a chart with far less competition than the full "Health & Fitness" chart.

Always check if your app qualifies for a specific sub-category rather than a broad parent. The visibility from a #5 sub-category ranking can exceed what you'd get at #50 in the parent category.

When to Change Your Category

Changing category is a legitimate ASO tactic, not a hack.

Indicators it's time to consider a change:

• Your app has been live 6+ months with minimal organic downloads from browse
• You're ranking well in keyword search but have no chart presence in your category
• You've added features that make a different category equally or more appropriate
• A category with less competition has emerged that now fits your app

Category changes on iOS require a new app submission (not an update — a full binary submission with the new category selection). On Google Play, you can change category in the app's store listing without a new binary.

The Practical Process

1. List every category your app could legitimately belong to (at least 3-5 options)
2. For each category, check the top 50 chart and note the #25 app's rating count
3. Identify the 2 categories with the weakest competition where you still fit
4. Check your primary keywords in search — does the search result page feature apps from those weaker categories?
5. Choose the category that balances competitive weakness with search relevance
6. After 60 days, evaluate chart ranking and organic install velocity — adjust if needed

Category selection isn't permanent. Treat it as a variable to optimize, not a box to check at launch.
