AppMetricsKit vs PostHog
PostHog is a broad, open-core product analytics platform built for product engineers. AppMetricsKit is a narrow, mobile-first tool for subscription apps that want privacy-label-ready analytics without adopting a larger platform.

Short answer
PostHog is a broad product platform with native iOS and Android SDKs, funnels, retention, session replay, feature flags, experiments, surveys, error tracking, and a data warehouse. Its mobile SDKs include privacy controls such as opt out, event filtering, person profile modes, and replay masking. On Android, session replay is disabled until enabled. AppMetricsKit is narrower. It supplies a canonical mobile subscription taxonomy, ready-made paywall and revenue dashboards, direct RevenueCat, Adapty, and Superwall webhook normalization, and store disclosure helpers. Choose PostHog when platform breadth and configurable analysis matter. Choose AppMetricsKit when a focused subscription workflow and a smaller operational surface matter.
When PostHog may be the better fit
- Product teams that want analytics, session replay, flags, experiments, and a warehouse from one open-core vendor.
- Products that span web and mobile and need one identity and analytics platform.
- Engineering-led teams that want configurable funnels, retention, SQL, and data warehouse connections.
- Teams that want mobile session replay with restrictive masking defaults and explicit enablement.
When AppMetricsKit is the better fit
- Mobile subscription apps that want paywall, trial, renewal, and MRR reporting as defaults rather than custom insights they build.
- Privacy-positioned apps that want payload filters, server PII detection, privacy findings, and store disclosure helpers in one workflow.
- Indie developers who want a smaller analytics product and subscription dashboards with less configuration.
- Teams using RevenueCat, Adapty, or Superwall that want provider webhooks normalized automatically.
| Dimension | AppMetricsKit | PostHog |
|---|---|---|
| Product scope | Mobile subscription analytics only | Analytics, replay, flags, experiments, surveys, warehouse |
| Source model | Proprietary SaaS with open-source SDKs | Open core; self deployment is possible but complex |
| Mobile collection defaults | Automatic launch tracking can be disabled before collection | Android lifecycle and screen capture enabled; replay disabled |
| Privacy controls | Payload filters, PII findings, and disclosure helpers | Opt out, event filtering, person profile controls, and replay masking |
| ATT prompt for core analytics | Not required | Depends on the complete configuration and data use |
| Subscription analytics | Canonical lifecycle events, paywall funnels, MRR | Buildable with custom events, funnels, and data sources |
| Provider webhooks | Direct RevenueCat, Adapty, and Superwall normalization | Can be modeled through PostHog's data platform |
| Free analytics allowance | 1 million events per month | 1 million events per month |
| Paid analytics pricing | Fixed EUR plans from 5 million events | Usage pricing per event, decreasing with volume |
Platform breadth versus product focus
PostHog consolidates product analytics, replay, feature delivery, experiments, surveys, error tracking, and warehouse tools. If a team will use several of those products, the shared platform and identity model are meaningful advantages.
AppMetricsKit deliberately covers less. Its default event taxonomy, reports, and integrations are designed around iOS and Android subscription apps. The choice is between a broad configurable platform and a smaller product that supplies more subscription conventions.
Mobile privacy posture
PostHog's Android SDK captures application lifecycle events and screen views by default, while session replay and automatic error capture are disabled until enabled. Its mobile replay uses wireframe mode and automatic masking by default. The SDK also supports opt out, event filtering, and controls over person profiles.
AppMetricsKit automatically tracks app launch only when collection and automatic launch tracking are enabled. It adds payload allowlists and blocklists, server-side PII detection, privacy findings, and App Store and Play disclosure helpers. Both products require a configuration-specific privacy review.
Subscription revenue out of the box
PostHog can model purchases, build paywall funnels, calculate retention, and join external revenue sources through its broader data platform. As of the review date, its official mobile SDK and product analytics documentation do not prescribe the same StoreKit and Play Billing lifecycle taxonomy or direct RevenueCat, Adapty, and Superwall normalizers documented by AppMetricsKit.
AppMetricsKit provides those event names, provider endpoints, and subscription dashboards by default. PostHog provides a more flexible toolkit for teams willing to design their own model.
Pricing
Both products include 1 million analytics events per month for free. PostHog publishes usage pricing that starts at $0.00005 for each additional product analytics event and decreases with volume. AppMetricsKit publishes fixed EUR tiers beginning at €29 per month for 5 million events. PostHog charges its other products separately, so compare the combined cost of replay, flags, warehouse rows, and analytics if you plan to use them.
Evaluation checklist
- Count the PostHog products you will actually use and price them together.
- Compare mobile defaults, person identity settings, event filters, replay masking, store disclosures, and consent controls.
- Build the same paywall and renewal reports in both tools before comparing setup effort.
- Review PostHog's current mobile SDK docs and pricing because the platform changes frequently.
Migration path to AppMetricsKit
- Identify which PostHog events are mobile subscription metrics versus broader product analytics you may keep in PostHog.
- Map mobile events to AppMetricsKit's taxonomy and retain any custom properties that support current reports.
- Run AppMetricsKit in test mode alongside the existing setup and verify in Live Events.
- Connect revenue provider webhooks, choose one source for each transaction, and then decide whether PostHog remains for other product surfaces.
The lowest-risk migration is not a one-day analytics swap. Keep the existing tool running, add AppMetricsKit in test mode, confirm the event taxonomy, then switch production reporting only after live events and dashboards match your product questions.
Frequently asked questions
Is PostHog good for mobile app analytics?
Yes. PostHog has native iOS and Android SDKs with events, identity, funnels, retention, feature flags, experiments, error tracking, and optional session replay. AppMetricsKit is more specialized around subscription taxonomy, provider event ingestion, and store disclosure workflows.
When should I choose PostHog over AppMetricsKit?
Choose PostHog when you want session replay, feature flags, experiments, or warehouse-level SQL access in the same product as analytics, or when your product spans web and mobile. PostHog also publishes most of its code, although its own documentation notes that self deployment can be complex.
Can I use both PostHog and AppMetricsKit?
Yes. A team can keep PostHog for broader product analytics, experiments, or replay while using AppMetricsKit for mobile subscription events and provider event ingestion. Account for the event volume, startup behavior, consent flow, and privacy disclosures of both SDKs.
Why subscription apps compare analytics tools differently
A subscription app does not only need page views or generic custom events. It needs to answer whether onboarding produces activation, whether the paywall is shown at the right moment, whether trial users convert, whether provider renewals and refunds appear without accidental duplicate client records, and whether analytics payloads can pass a privacy review. AppMetricsKit is built around those questions, so the comparison should weigh event taxonomy, SDK privacy defaults, revenue-provider support, retention windows, export needs, and the developer setup path.
