Free ASO tools & honest alternatives.
I built ASOTrendHQ as a free ASO tool for iOS and Android — keyword difficulty scoring, low-competition opportunities, competitor gap analysis, and daily rank tracking, no credit card. Here's how it honestly stacks up against the paid platforms you've probably been comparing.
ASOTrendHQ vs AppFollow
ASOTrendHQ is a free alternative to AppFollow for the keyword-research and competitor-analysis side of ASO. AppFollow is a paid platform that bundles ASO with review/reputation management; ASOTrendHQ focuses on keyword scoring, opportunity discovery, and rank tracking, and is currently free with no credit card. If you mainly need keyword and competitor data — not review-reply workflows — ASOTrendHQ covers it at no cost.

ASOTrendHQ is a free, indie-friendly alternative to Sensor Tower for app keyword research and competitor analysis. Sensor Tower is an enterprise market-intelligence platform with quote-based pricing typically out of reach for solo developers; ASOTrendHQ gives you keyword scoring, opportunity discovery, and rank tracking for free. If you need download/revenue estimates and ad intelligence at enterprise scale, Sensor Tower is the heavier tool — but for everyday ASO keyword work, ASOTrendHQ covers it at no cost.
See the comparisonASOTrendHQ vs MobileAction
ASOTrendHQ is a free alternative to MobileAction for ASO keyword research and competitor analysis. MobileAction offers a limited free plan and paid ASO/market-intelligence tiers; ASOTrendHQ gives you keyword scoring, opportunity discovery, and daily rank tracking for free with no credit card. For everyday keyword and competitor work, ASOTrendHQ is a no-cost option; MobileAction adds paid market-intelligence depth on top.
See the comparisonASOTrendHQ vs AppTweak
ASOTrendHQ is a free alternative to AppTweak for ASO keyword research and competitor analysis. AppTweak is a powerful paid ASO platform that splits its capabilities into separate products (ASO Intelligence, Market Intelligence, Search Ads, Reviews); ASOTrendHQ focuses on keyword scoring, opportunity discovery, and rank tracking, and is free with no credit card. If you need AppTweak’s market intelligence and depth, it is the heavier tool — but for everyday keyword work, ASOTrendHQ covers it for free.
See the comparisonASOTrendHQ vs ASOdesk
ASOTrendHQ is a free alternative to ASOdesk for ASO keyword research and competitor analysis. Both offer free tiers; ASOdesk also includes paid review-management and a deep ASO toolset across higher plans. ASOTrendHQ focuses on keyword scoring, opportunity discovery, and rank tracking, is free with no credit card, and does not cap the keyword catalog you can browse. If you need ASOdesk’s review workflows or enterprise data volumes, its paid tiers add that.
See the comparisonASOTrendHQ vs App Radar
ASOTrendHQ is a free alternative to App Radar for ASO keyword research and competitor analysis. App Radar is a paid ASO platform that also offers ad management, AI tools, and managed services; it has a limited free tier and a trial. ASOTrendHQ focuses on keyword scoring, opportunity discovery, and rank tracking, is free with no credit card, and does not cap the keyword catalog you can browse. If you want App Radar’s ad management or done-for-you services, its paid tiers add that.
See the comparisonASOTrendHQ vs data.ai (App Annie)
Looking for a data.ai alternative? data.ai (formerly App Annie) was acquired by Sensor Tower in March 2024 and is being consolidated into Sensor Tower’s enterprise platform, so it is no longer a standalone self-serve product. ASOTrendHQ is a free option for the ASO keyword side: difficulty/popularity scoring, low-competition opportunities, competitor gap analysis, and daily rank tracking across iOS and Android — no credit card. Enterprise download/revenue estimates and market intelligence now live inside Sensor Tower.

Honest trade-off: I run ASOTrendHQ as an independent side project. It does not include review-management workflows, ad/market intelligence, or paid support, and all metrics are estimates from public store data — not official Apple or Google figures. Competitor details on each page are accurate as of May 2026; always check each vendor's site for current pricing.
Frequently asked questions
What is the best free ASO tool?
ASOTrendHQ is a free ASO tool covering keyword difficulty and popularity scoring, low-competition opportunity discovery, competitor gap analysis, and daily rank tracking across the Apple App Store and Google Play — with no credit card required. Most established alternatives (AppFollow, Sensor Tower, MobileAction) are paid, though several offer limited free tiers.
Are paid ASO tools worth it for indie developers?
Paid ASO tools add depth most indie developers do not need at first — download/revenue estimates, ad intelligence, review-management workflows, and dedicated support. For core keyword research and rank tracking, a free tool like ASOTrendHQ usually covers the essentials, and you can upgrade to a paid platform later if you need the extras.
Do free ASO tools use real app-store data?
Yes, but the metrics are estimates derived from public app-store data, not official Apple or Google figures. ASOTrendHQ refreshes daily and shows a "last refreshed" timestamp on every page so you can judge how current the data is.
