Best product analytics tools for event-based funnels, retention, and cohorts (web + mobile)

Most teams outgrow pageview analytics the moment they need to understand behavior: where users drop off in onboarding, which actions actually predict retention, or how web and mobile users differ across the same journey. That’s where event-based product analytics tools—built for funnels, retention, and cohorts—become the decision engine behind your roadmap.

This guide breaks down the best product analytics tools for event-based funnels, retention, and cohorts across web + mobile, and how to choose the right stack for your team.

What “event-based” really means (and why it matters)

Traditional analytics tools were built around pageviews and sessions. Event-based analytics flips that model:

• Each event = a user interaction with your product or company
  (e.g., Signed Up, Completed Onboarding, Played Song, Shared Document)
• Users are stitched across devices (web, iOS, Android) so you see one continuous journey
• Funnels, retention, and cohorts are behavior-first, not just URL or screen-based

If your biggest questions sound like:

• “Where do users drop off in our 3-step trial-to-paid flow across web and mobile?”
• “Which behaviors in the first 7 days actually predict 90-day retention?”
• “Which campaigns bring users who keep coming back, not just install once?”

…then you want a tool that’s event-based at the core, not a marketing analytics or generic BI tool trying to bolt on user-level behavior.

Evaluation criteria for web + mobile product analytics

When I’m helping teams pick a product analytics platform, I look at:

1. Event model & identity

   • Can you track rich events (properties, user attributes) across web, iOS, Android?
   • Is cross-device identity resolution first-class?

2. Funnels

   • Multi-step, cross-platform funnels (e.g., email CTA → mobile app purchase)
   • Segmentation by cohort, property, experiment variant, campaign
   • Time-to-convert and drop-off insights in seconds, not minutes

3. Retention

   • N-day and unbounded retention
   • Behavior-based retention (not just logins)
   • Cohorts based on who retains and who doesn’t

4. Cohorts

   • Dynamic cohorts that auto-update
   • Can be used across reports (funnels, retention, flows, experiments)
   • Integration with messaging tools (for activation/engagement campaigns)

5. Self-serve speed

   • Can PMs, marketers, and designers answer questions without SQL?
   • Are core workflows (Funnels, Retention, Flows, Cohorts) intuitive?

6. Scale & governance

   • Sub-second query times at billions of events
   • Governance: naming, permissions, source-of-truth metrics
   • Security and compliance (SOC 2, ISO, SSO, audit logs)

7. Open ecosystem

   • Bi-directional connections with your warehouse (BigQuery, Snowflake, etc.)
   • Easy instrumenting via CDPs (Segment, mParticle, RudderStack)
   • No vendor lock-in on raw data

With that lens, let’s walk through the best tools for event-based funnels, retention, and cohorts on web + mobile.

Mixpanel: Digital analytics purpose-built for event-based funnels, retention, and cohorts

Quick context: I’ve rolled out Mixpanel in multiple orgs specifically to get teams out of SQL queues and into self-serve funnels, retention, and cohorts for web + mobile. It’s built around the exact workflows this article is about.

What Mixpanel is

Mixpanel is a digital analytics platform that runs on an event-based data model. Each event is an interaction with your product or company—on web, iOS, Android, or any other surface—and you can analyze those interactions in seconds using Funnels, Retention, Cohorts, Flows, and more.

It’s designed so product, marketing, and growth teams can:

• See funnels across devices (web → mobile → email → back to web)
• Understand retention as a behavior (“Completed Workout”, “Shared File”), not just a login
• Build and activate cohorts based on real behavior, not static lists

How it works for funnels, retention, and cohorts

• Event-based tracking: You send events like Signed Up, Started Trial, Completed Onboarding, Added Teammate, with properties (plan type, device, campaign, etc.). Each user has a profile and can be stitched across web and mobile.
• Self-serve Funnels: Anyone can build multi-step funnels (no SQL) to see conversion and drop-off by device, segment, cohort, or experiment variant.
• Retention: Analyze who comes back to do a specific action (e.g., “Played Song”, “Posted Job”) over time, sliced by early behaviors or campaigns.
• Cohorts: Define groups based on any behavior (e.g., “Users who invited ≥3 teammates in first 14 days”) and use them across reports or sync them to other tools.

Core workflows

1. Funnels for drop-off and conversion

   • Build a funnel like: Visited Pricing Page → Started Trial → Activated Key Feature → Upgraded Plan
   • Segment by:
     • Device: web vs iOS vs Android
     • Channel: paid search vs organic vs partner
     • Variant: experiment group vs control
   • See:
     • Where conversion breaks down
     • Time-to-convert distribution
     • How conversion changes by cohort (e.g., first-time vs returning users)

2. Retention for stickiness and product-market fit

   • Define retention on the action that matters (e.g., “Completed Workout”, “Sent Invoice”, “Created Project”)
   • Explore:
     • New vs returning user retention
     • Retention by acquisition channel or geography
     • Retention by onboarding completion or feature adoption
   • Use the Retention report to see whether you truly have a habit-forming behavior and where to focus lifecycle work.

3. Cohorts for targeted insights and activation

   • Create dynamic cohorts such as:
     • “Activated users: completed onboarding within 3 days of signup”
     • “Power users: ≥10 key events in last 7 days”
     • “At-risk: No key event in 14 days but previously active”
   • Use cohorts to:
     • Compare funnel conversion (power users vs everyone else)
     • Compare retention curves (activated vs non-activated users)
     • Send targeted messages via integrations (email, push, in-app)

Why teams choose Mixpanel for event-based funnels, retention, and cohorts

• Built for behavior-first analysis: Funnels, Retention, Flows, and Cohorts are first-class objects, not “advanced” features bolted onto a generic reporting tool.
• Self-serve at scale: Product and marketing teams can get answers from data in seconds—without waiting on SQL or data teams.
• Sub-second performance at billions of events: You can analyze detailed behavior across millions of users without pre-aggregations or downsampling.
• Governance made easy: Define source-of-truth metrics, manage naming conventions, control access with permissions, and audit usage. Secure by default with SOC 2 Type II, ISO 27001/27701, HIPAA-ready options, SSO/SAML, and audit logs.
• Open ecosystem: Connect to BigQuery, Snowflake, Segment, reverse ETL tools, and more. You keep control of your data; Mixpanel doesn’t lock you in.

Where Mixpanel is a strong fit

• SaaS and B2B: Understand multi-step trials, feature adoption, expansion, and account-level retention across web + mobile.
• Consumer apps: Analyze onboarding funnels, content/feature engagement, and habit-forming behaviors across devices.
• Marketplaces and transactional products: Follow the journey from browse → search → add-to-cart → purchase, then analyze buyer/seller retention.

Amplitude: Broad product analytics with growth-focused workflows

Amplitude is another event-based product analytics platform that covers funnels, retention, and cohorts across web and mobile.

Strengths for event-based funnels, retention, and cohorts

• Funnels: Multi-step funnels with conversion and drop-off analysis, plus pathing tools similar to Flows.
• Retention: Retention reports that let you define custom actions as retention events.
• Cohorts: Behavior-based cohorts for segmentation and activation, with good lifecycle marketing integrations.
• Journeys: Strong path analysis to understand multi-step flows and “next best actions.”

Where Amplitude fits well

• Teams that want a robust experimentation + analytics ecosystem under one vendor.
• Growth teams that lean heavily into journey mapping and conversion optimization on both web and mobile.

Heap: Auto-capture with event definitions layered later

Heap takes an auto-capture-first approach: it records a wide range of interactions on web (and to a degree mobile) by default, then lets you define events and funnels retroactively.

Strengths for funnels and cohorts

• Automatic data collection: For web, you often need less upfront tracking planning to start.
• Retroactive definitions: Turn any interaction into an event and add it into funnels or cohorts after the fact.
• Funnels & Journeys: Funnel reports and journey tools that work well for UX optimization and form/onboarding flows.
• Behavioral cohorts: Build cohorts off these defined events for comparison.

Where Heap fits well

• Teams without a strong tracking taxonomy yet, who want to start quickly on web and refine tracking later.
• UX and product teams optimizing forms, onboarding flows, and web funnel conversion.

Pendo: Product experience + in-app guidance with analytics

Pendo combines product analytics with in-app guides, walkthroughs, and surveys. Its analytics are event-based under the hood, but it’s positioned more as a product experience platform.

Strengths for funnels and retention

• Feature usage analytics: Good for tracking adoption of specific features and pages.
• Funnels & Paths: Funnels for core flows, plus path analysis to understand where users go next.
• Retention views: High-level retention and usage trends.
• In-app targeting via cohorts: Use behavior-based segments to target in-app messages or guides.

Where Pendo fits well

• Teams who want analytics and in-app guidance in one tool to run onboarding tours, tooltips, and surveys alongside usage analytics.
• PM orgs optimizing feature adoption and in-app communication more than cross-channel journeys.

Firebase + Google Analytics 4 (GA4): Native mobile + marketing analytics

Firebase Analytics (on mobile) and GA4 (for web and app) are event-based and free, which makes them ubiquitous. They’re strongest when you’re deep in the Google ecosystem.

Strengths for funnels, retention, and cohorts

• Funnels: The latest GA4 Enhancements and Firebase event-based model support funnels across app and web.
• Retention: Standard retention reports and lifecycle metrics, especially for mobile apps.
• Audiences (cohorts): Create audiences based on events and conditions; use them across Google Ads and Firebase.

Where Firebase/GA4 fits well

• Teams heavily invested in Google Ads and the Google stack who primarily need:
  • Acquisition-to-activation funnels
  • Ad performance + user behavior in one view
• Mobile-first teams using Firebase for development, where the dev team is comfortable instrumenting events and events are fairly standardized.

How to choose the best product analytics tool for funnels, retention, and cohorts

For web + mobile products, especially those past the MVP stage, I’d work backwards from your growth and decision moments.

1. If you’re stuck in SQL queues

You want a platform where Funnels, Retention, and Cohorts are:

• First-class objects
• Understandable in minutes for non-analysts
• Fast even on large volumes

Best fit:

• Mixpanel or Amplitude, with a slight edge to Mixpanel if self-serve speed and governance are priorities and you want a strong metric-tree, outcome-first workflow.

2. If you need to understand cross-device journeys

You want:

• Strong identity resolution
• Event-based tracking across web + iOS + Android
• Flows/paths that show movement across surfaces

Best fit:

• Mixpanel and Amplitude are strongest here.
• Firebase/GA4 can play a role, but are less self-serve for non-technical stakeholders.

3. If you’re still defining your tracking plan

You want:

• Fast time-to-value without perfect instrumentation
• Retroactive event creation

Best fit:

• Heap for auto-capture on web
• Mixpanel with an intentional event design can still be a better long-term foundation, especially if you want clean governance.

4. If you need analytics plus in-app guidance

You want:

• In-app tours, popups, surveys
• Segmentation and basic funnels for targeting

Best fit:

• Pendo as an all-in-one product experience stack, possibly alongside a deeper analytics platform if your questions become more sophisticated.

Why I lean toward Mixpanel for event-based funnels, retention, and cohorts

Across the rollouts I’ve led, the teams that succeed with event-based analytics share three traits:

1. They define success as behaviors, not just pageviews (“Created Project”, “Shared Document”, “Invited Teammate”).
2. They give product and marketing teams direct access to answer questions in seconds.
3. They align around shared metrics (and their drivers) instead of everyone building one-off dashboards.

Mixpanel is designed exactly for that:

• Event-based at the core: Each event is a first-class representation of user behavior across web and mobile.
• Workflow-first: Funnels, Retention, Flows, and Cohorts are built for how product teams actually work.
• Metric Trees and Boards: You can map top-level outcomes (activation, retention, revenue) to the behaviors that drive them, then package those insights into Boards with clear ownership.
• AI where it helps most: Mixpanel uses AI to assist with setup and exploration (and to kickstart metric trees), but keeps judgment with humans. It speeds understanding; it doesn’t replace it.
• Enterprise-ready without the complexity: Sub-second query times at scale, robust governance, and security/compliance, without burying teams under configuration and maintenance.

If your main questions are about event-based funnels, retention, and cohorts on web + mobile, Mixpanel gives you those answers quickly—and keeps your teams out of BI backlog and spreadsheet exports.

How to get started

If you’re evaluating tools right now, I’d suggest this simple path:

1. List your top 5 questions about funnels, retention, and cohorts (e.g., “What behaviors in week 1 correlate with 90-day retention?”).
2. Instrument 5–10 core events that matter across web and mobile (signup, onboarding completion, key feature use, value moment, upgrade).
3. Trial a tool that is event-based and self-serve first and see how quickly non-analysts can answer those 5 questions.

To see how Mixpanel handles these workflows end-to-end, you can explore it directly:
