ASOStacks

ASOStacks is a SaaS platform for improving app store visibility for iOS and Android apps. Its keyword research tool evaluates up to 20 terms across five countries at once, using popularity, a seven-factor difficulty score, and opportunity scores. Searched keywords are tracked automatically, with daily rank checks at 6:00 UTC, plus history, changes, and sparklines. The Country Opportunity Finder scans 30 App Store and Google Play markets for a keyword, and download estimates based on TTR curves cover positions 1 through 20. For competitor research, per-keyword breakdowns can include up to 25 competitors and details such as ratings, review velocity, market age, publisher diversity, and tier analysis. The service fetches publicly available app metadata, ratings, and reviews from Apple App Store and Google Play. It is available on Android, iOS, and the web, and can be used as an MCP connector for Claude without API keys. The Free plan includes 10 tracked keywords and two tracked apps. Pro is $19 a month; Studio is $49 a month and includes priority support, while API access is listed as coming soon.

ASOStacks combines keyword research, rank tracking, market scans, download estimates, and competitor analysis for iOS and Android apps. The Free plan has defined tracking limits, while paid plans raise those limits and Studio adds priority support.

ASOStacks suits app publishers who need keyword research, daily ranking information, market opportunity scans, or competitor breakdowns for iOS and Android apps. Its Free plan may suit users with modest tracking needs; larger tracked keyword and app limits are listed on paid plans.

ASOStacks is an app store optimization service for teams working on iOS and Android listings. It is best for developers and marketers who need keyword discovery across both stores, with tracking quotas that suit a small portfolio or a growing operation on a paid plan. The main trade-off is clear: broad market research comes with rank checks once a day and firm limits on tracked apps and keywords.

Overview

ASOStacks brings keyword research, rank tracking, market scans, download estimates, and competitor analysis together. It draws publicly available app metadata, ratings, and reviews from the Apple App Store and Google Play. The service is offered on the web, Android, and iOS, and its MCP connector lets Claude users connect without API keys.

Its security and data practices are relevant for teams handling account information: ASOStacks says it uses TLS in transit, encrypted storage, access controls, and regular security reviews. It also says it does not sell personal data or use it to train AI models without explicit consent. Creem processes payments, and ASOStacks says it does not store card numbers or full payment credentials on its servers.

Key features

Research and market discovery

Keyword research scores as many as 20 terms across five countries at once, weighing popularity, seven-factor difficulty, and opportunity. The Country Opportunity Finder scans 30 App Store and Google Play markets for a keyword. That makes ASOStacks useful for comparing search prospects across regions; the research limits on Free, however, mean frequent exploration can push a user toward a paid plan.

Rank tracking and estimates

Searched keywords are tracked automatically, with daily rank checks at 6:00 UTC, history, deltas, and sparklines. The history and trend indicators help users follow movement over time, but checks once per day are a constraint for teams that need more frequent updates. Download estimates use TTR curves to estimate downloads per day for positions one through 20, giving users a position-based view of potential performance.

Competitor analysis

Per-keyword breakdowns cover up to 25 competitors and include ratings, review velocity, market age, publisher diversity, and tier analysis. This gives marketers several angles for judging a keyword's competitive landscape, rather than relying on rank alone. The reports still sit within account-level app and research quotas on the lower plans.

Pricing

ASOStacks has a free plan and two monthly paid plans. Free is $$0 billed forever. It allows 10 tracked keywords and two tracked apps, with daily rank checks, 20 keyword researches per day, one opportunity scan per day across 30 countries, five app reports per day, and five AI tool runs per day. That is a useful way to start with a small portfolio, but the tracking caps and daily research allowances make it a poor fit for managing many apps or sustained high-volume research.

Pro costs $19 a month, billed monthly. It raises capacity to 250 tracked keywords and 25 tracked apps, while providing daily rank checks with history and unlimited keyword research, opportunity scans, app reports, and AI tool runs. It is the practical tier for a working ASO portfolio that has outgrown Free; the fixed daily check schedule remains in place.

Studio costs $49 a month, billed monthly. It includes everything in Pro, raises the limits to 1,000 tracked keywords and 100 tracked apps, and adds priority rank checks and priority support. API access is marked as coming soon, so it is not a current reason to upgrade. Studio suits larger portfolios that need more tracking capacity or priority service; smaller teams may not need its higher ceilings.

Platforms

ASOStacks supports Android, iOS, and web, while its store data and ASO tools focus on Apple App Store and Google Play. Claude users can also connect through the MCP connector without API keys. That combination covers teams working across the two main mobile storefronts, though the tools do not promise coverage beyond them.

Who it's for

ASOStacks fits app developers and marketers who want research, monitoring, and competitor context for a portfolio on both major app stores. Free is a sensible starting point for a couple of apps and light research. Pro is better for ongoing work across up to 25 apps, while Studio is aimed at teams whose tracking needs exceed Pro or who value priority checks and support.

It is less suitable for teams that require multiple rank updates each day, or whose portfolio exceeds 100 tracked apps. Its usefulness also depends on whether the account-level quotas fit the team's research and reporting workload.

Pros and cons

• Pros: The 30-market opportunity scan and five-country keyword scoring help teams compare markets and terms across both major stores.
• Pros: Competitor reports include review velocity, publisher diversity, and market age alongside ratings, supporting a broader read of keyword competition.
• Pros: Pro removes daily limits on research, scans, reports, and AI tool runs while supporting 25 tracked apps for $19 a month.
• Cons: Rank checks run daily at 6:00 UTC on Free and Pro, which limits usefulness for teams that need more frequent monitoring.
• Cons: Free is capped at 10 tracked keywords and two apps, and its research, scan, report, and AI allowances are also limited per day.
• Cons: Studio costs $49 a month, and its API access is still coming soon.

Verdict

ASOStacks is a strong fit for developers and marketers who need keyword research and competitor insight across Apple App Store and Google Play, especially when Pro's 25-app limit and unlimited research suit their workflow. Its clearest reason to choose it is the combination of broad market discovery and defined, scalable tracking tiers. Look elsewhere if you need multiple rank checks per day, or if your app portfolio exceeds Studio's 100-app ceiling.
