Sensor Tower alternatives for indie developers
If you landed on Sensor Tower's site looking for a price and found a “talk to sales” page instead, you're not the customer it's built for. Its market-intelligence platform is priced for companies and investors, not a single developer's keyword tracking.
None of Sensor Tower's plans are priced for a single developer; independent transaction data puts the median deal size in the tens of thousands of dollars a year. ASOHawk (free to start) and Astro ($9/mo flat) both let you sign up and see the product today, no sales call required. If you do need more market-wide data than either provides, AppTweak is the middle ground: still self-serve, still far below Sensor Tower's pricing. (Disclosure: we built ASOHawk.)
Sensor Tower is built for a different question than most developers researching ASO tools are actually asking. It's market intelligence at an industry or portfolio level, used by publicly traded companies and investors to estimate download and revenue trends across apps they don't own, not a self-serve keyword tracker for a single app. There's no pricing page and no signup button; every plan starts with a sales conversation, and independently reported transaction data puts the median annual spend in the tens of thousands of dollars.
If what you actually need is keyword tracking, competitor visibility, and a signup button you can click today, here's what to use instead.
| Tool | Starting price | Self-serve signup | Keywords | Best for |
|---|---|---|---|---|
| Sensor Tower | $25k+/yr | No | Custom | Market intelligence, industry-wide |
| ASOHawk | Free | Yes | 30–300 | Solo devs, AI-agent workflow |
| Astro | $9/mo | Yes | Unlimited | Manual keyword tracking on a Mac |
| AppTweak | €79/mo | Demo only | 500–3,000 | Funded teams needing deep history |
Why these three
ASOHawk, if you want a self-serve signup today
ASOHawk's free plan is live and self-serve: 2 apps, 30 keywords each, no card, no sales call. It's a different order of magnitude of tool than Sensor Tower, built for one developer's own app rather than industry-wide analysis. Disclosure: we built it. Full write-up in the main ranking →
Astro, for a flat, simple fee
Astro is $9/mo flat for unlimited keywords and apps on a Mac, with no sales process and no custom quote. Full write-up in the main ranking →
AppTweak, if you genuinely need more market-wide data
If Sensor Tower's pull was its broader market data rather than its price, AppTweak is the closest self-serve middle ground: still a fraction of Sensor Tower's pricing, with years of historical ranking data most solo-focused tools don't have. Full write-up in the main ranking →
Frequently asked questions
Why doesn't Sensor Tower publish pricing?+
It sells market-intelligence contracts sized to each customer's needs, typically companies and investors rather than solo developers, so pricing is negotiated per deal rather than published as a fixed tier.
How much does Sensor Tower actually cost?+
There's no public number, but independently reported transaction data puts the median annual spend in the tens of thousands of dollars, with entry deals reported around $500/mo (roughly $6,000/yr) at the low end.
Is there a free or self-serve alternative to Sensor Tower for a solo developer?+
Yes. ASOHawk has a permanent free tier with no card required, and Astro is a flat $9/mo self-serve signup; neither requires a sales call.
What does Sensor Tower do that smaller ASO tools don't?+
It estimates download and revenue figures across the entire app economy, including apps you don't own, useful for market research and competitive intelligence at an industry level, not single-app keyword optimization.
