ASOTools

ASOTools is an app-store optimization and market-data service for developers and app teams. It is most compelling for people comparing keywords, rankings, and app performance across countries. Its free tools make it possible to start small, but daily quotas shape how much research you can do before upgrading.

Overview

ASOTools brings app analytics and market research for Android and iOS into one service, with coverage across 46 countries and 56 categories. Teams can move from an individual app’s performance to category and country rankings, a useful combination when deciding where to focus an app’s growth work. The trade-off is that the free and Basic plans cap daily searches and detail views, so broad or repeated research may require a higher tier.

Key features

App and market analytics

App analytics include listing details, localized product previews, developer profiles, review and rating changes, download trends, and estimated revenue. Download and revenue rankings by category and country, alongside store charts and market trends, help frame individual results against wider market activity. Popular apps and apps added to a subscription are updated daily, which suits teams monitoring selected titles; it is not a blanket daily-refresh promise for every app.

Keyword research and extension

Keyword tools cover search volume, difficulty, popularity, coverage, rankings, and suggestions for Google Play and the App Store. Keyword tracking, competitor tracking, and listing localization round out the optimization workflow. The free Chrome extension focuses on Google Play: it shows marketing metrics and keyword analysis, including monthly download and review-change calculations, the current version, and publish date. Its keyword checker stops at the 10 top-ranked keywords for each app, so it is a convenient quick look rather than a substitute for deeper keyword work.

API and data handling

ASOTools supports data API integration and offers API cooperation, making it relevant to teams that want app data in connected workflows. The service says data is transmitted with end-to-end encryption, payments go through Stripe and meet CPI standards, and its privacy policy describes encryption for electronic transactions, protected personal-information storage, and GDPR measures including data rights, breach notification, and a designated Data Protection Officer. Business or API cooperation, press and product feedback, and enterprise demo inquiries have separate email contacts.

Pricing

The Free plan costs nothing and allows 3 search queries daily. That is enough for occasional checks, but too restrictive for sustained discovery. Basic costs $9 a month (billed $9 /mo) and raises the allowance to 10 app searches, 20 keyword searches, and 50 detail views each day, with download and revenue rankings capped at Top 200. It is a sensible low-cost step up for light research, but the daily limits and ranking depth constrain heavier analysis.

Growth costs $59 a month (billed $59 / mo) and includes 100 daily app searches, 200 daily keyword searches, 500 daily detail views, and tracking for 10 apps. A 3-day trial for $1 lets a team evaluate that larger working allowance before committing, though the short trial is best treated as a focused evaluation. Business costs $299 a month (billed $299 /mo) and removes caps on keyword and app searches and detail popups, tracks 30 apps, and provides download and revenue estimates for 180 days. It fits teams with substantial research volume and a need for longer estimates; the jump in price is hard to justify for occasional or small-scale use.

Platforms

ASOTools is available on the web and through an API and browser extension. The extension is for Chrome and Google Play, while the main coverage includes both Android and iOS apps. That mix works for teams spanning platforms, although extension keyword analysis is limited to Google Play.

Who it's for

Individual developers and small teams can use the free tools or Basic to investigate a narrow set of apps and keywords. Growth is better suited to regular tracking and daily research; Business is aimed at organizations that need high query volume and 30 tracked apps. Teams whose work depends on more than 10 extension keywords per app should base their workflow on the main service rather than the extension alone.

Pros and cons

• Broad market coverage: 46 countries and 56 categories make cross-market comparisons practical for Android and iOS teams.
• Connected research workflow: App analytics, keyword tools, rankings, tracking, localization, and API access cover several stages of ASO work.
• Useful free starting point: Free tools and a free extension reduce the barrier to occasional checks, but the plan allows only 3 daily search queries.
• Clear scale-up path: Growth adds meaningful daily capacity and tracking for 10 apps, while Business removes search caps; the latter costs $299 a month.
• Extension ceiling: Its checker analyzes no more than 10 top-ranked keywords per Google Play app, limiting deeper keyword review in the extension.

Alternatives

App Store Optimization Software is the broader category directory for comparing options. ASOdesk is worth considering when its free plan’s 200 keywords, one application, one teammate, and 100 monthly API credits better match a tightly scoped workflow. AppFollow may suit teams prioritizing its free plan’s two apps, 10 competitor apps, and 100 manual replies per month, with seven days of historical data. AppTweak is an alternative for users who want a free Market Intelligence Starter plan with three seats, past-month historical data, and download and revenue estimates.

ASOMobile offers a free plan with 20 keywords, two apps, one teammate, 10 competitors, and 100 review responses, which may fit a small team focused on those allowances. KWRDS is a free option for iOS and macOS users needing 10 tracked ranking keywords for one app and limited keyword research. Appstro is another free option. ASO.dev is a paid alternative with a broader platform range, including desktop systems and mobile platforms. ASOScan is worth comparing if a paid Solo plan with three apps, 500 total keywords, and 10 competitors per app better fits the workload.

Verdict

ASOTools is a strong fit for app developers and teams that need app, keyword, and market research across Google Play and the App Store, especially when country-level rankings matter. Its free entry point and escalating search capacity make it approachable, but daily caps on lower tiers and the extension’s 10-keyword ceiling are real constraints. Choose it for a joined-up research workflow; look elsewhere if your needs center on a different specialized workflow or you cannot justify the higher-volume plans.
