App Discovery

Building apps is fast now. AI handles the development. The real challenge is choosing the right idea — one that people actually want, in a market that isn’t already saturated by established players.

App Discovery helps you research what works in the market before you invest time building.

Browse the top 200 free, paid, and top-grossing apps from the iOS App Store and Google Play, directly inside Primio.

Access it from the side menu → Discover, or navigate to the Discover page. You need a Primio account to use it.

The page displays three columns: Top Free, Top Paid, and Top Grossing.

Filter the rankings by:

  • Store — iOS App Store or Google Play
  • Country — any available market
  • Category — all categories, with subcategories for Games (Action, Adventure, Arcade, Board, etc.)
  • Device type (iOS only) — iPhone or iPad

Click any app to see its detail page.

Use the search bar to find specific apps by name. Search results show rank badges indicating where the app appears in the rankings — for example, “#12 Free” and “#45 Grossing” — so you can quickly see how well it performs across different lists.

Click any app (from rankings or search results) to see:

  • App icon, name, and developer
  • Screenshots carousel
  • Description, reviews, and ratings
  • Category and pricing information

Here are practical ways to use App Discovery for inspiration:

Look for gaps. Simple apps ranking high in a category suggest the market is underserved. If a basic flashlight app is in the top 50, there’s room for something better.

Study reviews. Read negative reviews of top apps. Complaints are opportunities. “I wish this app had offline mode” or “The UI is confusing” tells you exactly what to build differently.

Check different countries. What’s popular in mobile-first markets (India, Nigeria, Southeast Asia) may not exist in your local market yet. Cross-market inspiration can reveal untapped opportunities.

Browse categories. Spend time in categories you wouldn’t normally look at. Patterns emerge — utility apps with simple value propositions often outperform complex ones.

Follow the money. The Top Grossing column shows where users actually spend money. If a category has many top-grossing apps, there’s proven willingness to pay.

On any app’s detail page, click Build Something Similar. Primio creates a new project inspired by that app. You describe what you want to change, improve, or do differently in your first prompt.

This is a starting point for your own original app, not a cloning tool.

  1. Research your target category

    Browse rankings in the category and country you’re targeting. Spend time exploring what’s already out there.

  2. Identify 3-5 comparable apps

    Find apps that serve a similar audience to what you have in mind.

  3. Read their reviews

    What do users love? What do they complain about? The complaints are your opportunities.

  4. Define your unique angle

    Better design, a missing feature, a more focused niche, simpler UX — find what makes yours different.

  5. Start building

    Click “Build Something Similar” on the closest match, then describe your improvements in the first prompt.

  6. Iterate based on the market

    Come back to App Discovery as you build. Check how competitors handle specific features for reference.
