App Analytics Tools Compared (2026): Free Defaults, Paid Cliffs, and What Indie Devs Actually Need

If you're an indie developer choosing an app analytics tool in 2026, the honest answer is that most of you should start with Google Analytics for Firebase, because it's free with unlimited volume, and only pay for something else when you hit a specific wall. Mixpanel and Amplitude both offer free tiers big enough to run a small app indefinitely — 1 million events a month at Mixpanel, 2 million at Amplitude — and the real differences only show up in what happens after you outgrow them. TelemetryDeck is the pick if privacy positioning matters to you, and Appfigures is the pick if what you actually want is store analytics — downloads, revenue, reviews — rather than in-app behavior. Here's how they compare, and where each one wins.

First, decide which "analytics" you mean

"App analytics" gets used for two different jobs, and buying the wrong category is the most common mistake.

Product analytics tells you what users do inside your app: which screens they hit, where onboarding leaks, what retention looks like at day 7. Firebase, Mixpanel, Amplitude, and TelemetryDeck live here.

Store analytics tells you how your app performs as a listing: downloads, revenue, subscriptions, keyword ranks, reviews. Appfigures lives here, alongside the ASO suites we've compared before on this desk.

Most indie apps eventually want one of each. The good news is that in 2026 you can cover both jobs for very little money — sometimes none.

Firebase: the free default that's hard to argue with

Google Analytics for Firebase costs nothing. Google's own page puts it plainly: "There's no cost to using Google Analytics," with free, unlimited reporting on up to 500 distinct event types and no volume caps. You also get BigQuery export for raw data, Crashlytics integration, and hooks into Remote Config and A/B testing.

Where it wins: price (unbeatable), volume (unlimited), and ecosystem — if you're already on Firebase for auth or crash reporting, analytics is one checkbox away.

Where it loses: the reporting UI is built for Google's ad ecosystem first and product questions second. Funnel and retention analysis is workable but clunky compared to purpose-built tools, and serious custom analysis effectively means learning BigQuery. The 500-event-type ceiling is generous but real. And if your users — or your conscience — are wary of shipping behavioral data into Google's advertising machine, that's a reason people pay for alternatives.

Mixpanel: the strongest free tier for funnels

Mixpanel's free plan now includes up to 1 million events a month, unlimited seats, funnels and retention analysis, 10,000 session replays, and even up to 10 feature flags. For a solo dev with a modest user base, that's a full product-analytics stack for $0. The paid Growth plan starts at $120/month billed annually ($140 monthly) and scales to 20 million events. There's also a startup program: companies under 5 years old with up to $8M in funding get their first year free.

Where it wins: the analysis UI. Funnels, cohorts, and retention views are faster to build and easier to read than Firebase's, and session replay on the free tier is a genuine differentiator.

Where it loses: the price cliff. The jump from $0 to $120+/month is steep for an indie app that drifts just past a million events. Watch your event volume before you instrument everything that moves.

Amplitude: the biggest free ceiling

Amplitude's free plan includes 2 million events a month — double Mixpanel's — plus session replay (10K/month), feature flags, surveys, and unlimited seats. Its Plus tier is usage-based beyond the free allowance and scales up to 70 million events a month, adding custom formulas, behavioral cohorts, alerts, heatmaps, and 2-year data retention; Growth and Enterprise are custom-priced.

Where it wins: free headroom and depth. Amplitude's behavioral analysis is arguably the most sophisticated of the group, and 2M free events is the largest allowance among the purpose-built tools here.

Where it loses: complexity. Amplitude is built for product teams running experiments, and a solo developer can drown in its concepts before answering the only question that matters early on: where do people quit? If you just need funnels and retention, Mixpanel or even Firebase gets you there with less ceremony.

TelemetryDeck: the privacy-first indie option

TelemetryDeck markets itself as privacy-first analytics, and it's priced for small developers. As of its July 2026 pricing update, the free tier covers 50,000 events a month for new accounts (existing accounts keep a grandfathered 100,000), with paid tiers stepping up more gradually than before — including a new 2.5M-event tier between the old 1.5M and 5M steps. Note that July 2026 also brought its first price increase since 2023, with existing customers grandfathered.

Where it wins: privacy posture and indie fit. If "we don't feed Google" is a selling point to your users, this is the tool in this list built around that pitch.

Where it loses: raw scale and analysis depth. A 50K-event free tier is a fraction of Mixpanel's or Amplitude's, and you won't find session replay or experimentation suites here. It's deliberately smaller — that's the trade.

Appfigures: when the question is the store, not the app

Appfigures answers a different question: how is your app doing as a business? Download and revenue tracking, subscription analytics, review management, and keyword tracking, starting at $9.99/month (Connect, 5 apps, 25 keywords) after a limited free plan. Monitor at $44.99/month adds daily keyword rank updates; Optimize at $149.99/month adds competitor tracking; tiers run up to $1,399.99/month for full market intelligence. Annual billing takes roughly 20% off.

Where it wins: consolidation. One inexpensive dashboard for downloads, revenue, and reviews across both stores is still Appfigures' core appeal, as we noted in our fuller review.

Where it loses: it won't tell you anything about in-app behavior. Pair it with one of the tools above rather than instead of them.

So which one?

Start free: Firebase if you want zero cost and don't mind Google; Amplitude if you want the biggest free allowance from a purpose-built tool; Mixpanel if you want the most pleasant funnel UI with session replay. Pick TelemetryDeck if privacy is part of your product's pitch and your volumes are modest. Add Appfigures (or a similar store-side tool) when store performance becomes the question. And check the prices yourself before committing — every figure here was verified on the vendors' own pages in late August 2026, and this category reprices often, as TelemetryDeck's July increase shows.

For what it's worth: at Kintsu (our own product, currently in private beta, built for indie devs) we sit on the store side of this divide — reviews and store data — which is exactly why we'd tell you a product-analytics tool belongs in your stack alongside it, not instead of it.

FAQ

Is Firebase Analytics really free with no catch? The analytics product itself is free with unlimited report volume, per Google's own page. The practical limits: 500 distinct event types, and costs appear if you export raw data to BigQuery at scale. The other "catch" is strategic — your behavioral data lives in Google's ecosystem.

Mixpanel or Amplitude for a solo developer? On free-tier size alone, Amplitude (2M events/month vs 1M). On day-to-day usability for simple funnel and retention questions, many find Mixpanel quicker to get answers from. Both give you unlimited seats and session replay for free, so trying both on a side project costs nothing but setup time.

Do I need both a product analytics tool and a store analytics tool? Eventually, usually yes. Product analytics can't see your revenue, rankings, or reviews; store analytics can't see what users do after install. Most indie stacks end up with one of each — both available free or under $10/month at entry level.
