AppBrain vs ASOStacks

AppBrain provides Android app market data and tools for research, promotion, and monetization. Its Intelligence product covers over 2 million Android apps, with more than 10 years of historical data across 30+ countries and daily refreshes. Researchers can review download trends over time, rankings, competitor comparisons, and country-level breakdowns. Keyword Tracker supports daily rank tracking across 30+ countries, AI-assisted keyword discovery, and competitor keyword gap analysis. For promotion, AppBrain offers cost-per-install campaigns with audience targeting, non-incentivized installs, and real-time reporting. Android developers can integrate its SDK through a Gradle dependency to show interstitial ads. AppBrain does not host app files or APKs; install links direct users to the official store. Intelligence subscriptions attach to an organization account where coworkers can be invited and managed through a dashboard. The free plan includes up to 20 tracked keywords, basic app details, developer overviews, and browsing of over 2 million app pages. An App Performance Report costs 29.00 USD one-time, with no subscription. Intelligence costs $75 a month. Its three-day Intelligence trial requires a payment method up front, and subscriptions auto-renew unless cancelled up to three days before renewal.
