Is Sensor Tower worth it for indie developers?

From the SoleOS answers series — written about our own product space; grounded in published definitions and documented behavior, never invented numbers.

For most solo and small-team developers, Sensor Tower is not worth it. It's priced and built for market research teams tracking competitors and category trends, not for founders who need to know how their own five to twenty apps are actually performing. If your question is "how is my portfolio doing," you want your own store, payment, and analytics data pulled into one place — not modeled estimates about someone else's app.

That said, there's a narrower case where Sensor Tower earns its keep, and it's worth being precise about where that line sits before you commit a few hundred dollars a month to it.

What Sensor Tower actually does

Sensor Tower is a mobile market intelligence platform. It estimates download volumes, revenue, and ad spend for apps across the App Store and Google Play — including apps you don't own — using a mix of panel data, app store metadata, and modeling. Its core value is competitive: keyword rankings, category benchmarking, ad creative intelligence, and "what is this other app doing that's working."

That's a genuinely useful category of tool. If you're deciding whether to enter a crowded subcategory, want to see which keywords a competitor ranks for, or need to estimate the size of a market before building into it, Sensor Tower (or its rival Data.ai/data.ai successor products) gives you directional numbers you can't get any other way.

The catch: those numbers are estimates about apps you don't have data access to. For your own apps, you already have the real numbers sitting in App Store Connect, Google Play Console, RevenueCat, and Stripe. Paying for a modeled estimate of your own revenue when you have the exact figure one login away is the wrong trade.

Where Sensor Tower stops being useful for solo builders

Three friction points show up quickly for a one-person shop running several apps:

Pricing is built for teams, not individuals. Sensor Tower's plans scale with seats and query volume in a way that assumes a marketing or ASO team, not one person checking numbers between builds. You end up paying for capacity you'll never use.

It doesn't touch your web products. If any of your apps have a web or SaaS component — a landing page, a Stripe-billed subscription tier, a companion web app — Sensor Tower has nothing to say about it. It's mobile-store-only. A portfolio that spans web and mobile needs a tool that spans web and mobile.

Competitive intel isn't operational intel. Knowing a competitor's estimated downloads doesn't tell you whether your own churn spiked this week, which app in your portfolio is quietly bleeding subscribers, or whether your Search Console impressions dropped because of a Google update or a broken sitemap. Those are the numbers that actually change what you do on a Tuesday.

What most solo founders actually need instead

If the real question is "how is my portfolio doing," the fix isn't a market intelligence platform — it's consolidating your own first-party data: App Store Connect and Play Console for installs and store revenue, RevenueCat or Stripe for subscription and payment truth, GA4 and Search Console for web traffic, and PostHog or Firebase for product usage. Individually these are all free or cheap; the cost most founders actually pay is the time spent tab-switching between five dashboards to answer one question.

That's the gap SoleOS is built for — it's portfolio intelligence for multi-product founders, pulling metrics from Stripe, RevenueCat, GA4, Search Console, Bing Webmaster, App Store Connect, Google Play, Firebase, and Supabase into one view across up to 40 projects, depending on plan. Full disclosure: SoleOS is written by the team building it, so take the comparison with that in mind.

Where SoleOS is a bad fit: if you run a single app and check one dashboard already, or if your real need is competitive research (keyword rankings, competitor revenue estimates, ad spend intelligence) rather than tracking your own numbers, SoleOS won't help — that's still Sensor Tower's or a keyword tool's job. SoleOS doesn't estimate anyone else's numbers; it only reads data from accounts you connect yourself, and it's not a replacement for ASO keyword research.

For everyone else, the honest starting point is usually just a spreadsheet — it's free and it works fine until the tab-switching cost gets high enough that consolidating pays for itself. You can see exactly what SoleOS connects to and what scopes it requests before deciding, and the metrics dictionary lays out the exact formulas so you're not trusting a black box.

A simple test before you buy either tool

Before subscribing to Sensor Tower, RevenueCat's own dashboard extras, or SoleOS, write down the three questions you actually check every week. If two of three are "what is competitor X doing," you need market intelligence — Sensor Tower is a reasonable buy. If two of three are "is my own MRR up or down, and why," you need portfolio intelligence, and the modeled-estimate tool won't answer that no matter how good its data science is.

A related trap: even when founders do consolidate their own numbers, they often expect Stripe and RevenueCat to agree exactly and get confused when they don't. Worth reading how Stripe and RevenueCat numbers diverge before you assume any dashboard — Sensor Tower, SoleOS, or otherwise — is "wrong" when it just reflects a timing or definition difference between sources.

If you're running a real multi-app portfolio and curious whether the consolidation is worth it beyond spreadsheets, real numbers from an actual 10-app portfolio is a more honest read than any vendor's pitch page.

Frequently asked questions

Does Sensor Tower track my own app's real revenue accurately?

No — for apps you don't own, Sensor Tower produces modeled estimates from panel data and metadata, not exact figures. For apps you do own, you have exact revenue already in App Store Connect, Play Console, RevenueCat, or Stripe, so there's no reason to rely on an estimate of your own numbers.

Is there a cheaper Sensor Tower alternative for solo developers?

For competitive keyword and ranking research specifically, Appfigures and similar tools offer lighter-weight, more solo-friendly pricing. For tracking your own portfolio's real performance rather than competitors, you don't need a market intelligence tool at all — a spreadsheet or a portfolio dashboard pulling your own store and payment data does the job at a fraction of the cost.

Can Sensor Tower replace App Store Connect or Play Console analytics?

No. Sensor Tower estimates market-wide figures; App Store Connect and Play Console give you your own exact install, revenue, and ranking data for free. Use Sensor Tower to see how you compare to others, and the native consoles (or a dashboard that pulls from them) for ground truth on your own apps.

When does Sensor Tower actually pay for itself?

When you're making a decision that depends on market size or competitive positioning — entering a new subcategory, pricing against a known competitor, or evaluating whether a keyword is worth chasing. If your weekly questions are internal (churn, MRR trend, which app is declining), that spend is better put toward consolidating your own data sources.

Do I need both Sensor Tower and a portfolio dashboard?

Some founders do — one for market awareness, one for operational tracking — but most solo developers running under a handful of apps get more immediate value from operational tracking first. Start with your own numbers; add competitive intelligence tools once you have a specific market question you can't answer any other way. You can try the live demo or check SoleOS pricing to see if the operational side is worth solving before adding a market research subscription on top.
