Hi, I’m Rey I built RankingCheck as an indie developer to solve a simple problem: tracking app rankings across countries shouldn’t be slow, manual, or limited. So I built a tool that gives you real global visibility, without switching regions or relying on complex ASO platforms. WHAT YOU CAN DO Global Search Find any app and instantly see where it ranks across 170+ countries and 26 categories. Go deeper with extended multi-country scanning. Real-Time Rankings Always see what’s live. Rankings are refreshed frequently so you can track movement as it happens. Track Your Apps Add your app in one tap and monitor its performance over time across multiple countries. Ranking History Visualize trends and understand how your app moves in the charts. Competitor Comparison Compare your app with up to 4 competitors and see who’s rising or falling. Top Movers Spot rising and falling apps in real time across your tracked countries. Instant Alerts Get notified when your app enters the Top 50, Top 10, or makes significant jumps. ASO Keywords Analyze any app’s keyword strategy. Extract keywords from title, subtitle, and description. Daily Rankings Discover trending apps every day from different countries and categories. Home Screen Widgets Keep your most important rankings visible at all times with live widgets, including Top Movers. Share Your Ranking Generate clean, shareable ranking cards for social media in one tap. Built by an indie developer, for developers who want real control over their app’s performance.
