Mobile App Analytics Tools Comparison: Mixpanel vs Amplitude vs PostHog (2026)

If you're shipping a mobile app in 2026, you'll use one of three analytics tools: Mixpanel, Amplitude, or PostHog. (Or Firebase Analytics, which we'll cover as the lightweight default.)

This is the honest comparison.

TL;DR

• Mixpanel: best free tier (1M events/month). Industry standard. Easiest onboarding.
• Amplitude: best for cohort analysis + retention curves. Enterprise polish; generous free tier.
• PostHog: open-source. Best for self-hosting and full data control. Includes feature flags + A/B testing.
• Firebase Analytics: free, integrated with Google. Limited but fine if your needs are basic.

For most indie devs at indie scale, all four are free. Pick based on user experience and roadmap fit.

What you actually need from analytics

Three jobs:

1. Funnel tracking — install → activate → engage → convert → retain.
2. Cohort retention — plot retention curves by acquisition source, country, plan.
3. Event flow analysis — which sequences of actions correlate with retention?

Plus optional but useful:

4. A/B testing — built-in or via integration.
5. Push notification triggers — via integration.
6. Feature flagging — for staged rollouts.

Mixpanel

Strengths

• Most generous free tier in 2026: 1M events/month, 1k user profiles.
• Best documentation for cohort + funnel analysis.
• Industry standard — engineers and analysts know it.
• Strong integration ecosystem (Segment, RevenueCat, etc.).

Weaknesses

• Pricing scales sharply once you exceed free tier.
• Cohort analysis is good but less deep than Amplitude.
• Some advanced features behind paid tiers.

Pricing (2026)

• Free: 1M events/month.
• Growth: $25/month + usage above free.
• Enterprise: custom.

Best for

• First-time mobile apps.
• Teams that need broad event-based analytics.
• Apps that integrate with many other tools.

Amplitude

Strengths

• Best-in-class cohort retention analysis. Visual retention curves out-of-box.
• Strong "Pathfinder" for event flow analysis.
• Generous free tier.
• Better for product analytics than acquisition analytics.

Weaknesses

• Steeper learning curve than Mixpanel.
• More expensive at scale.
• Less generic event-tracking flexibility.

Pricing (2026)

• Free: ~10M events/month (varies by plan).
• Growth: $40+/month, usage-based.
• Enterprise: custom.

Best for

• Subscription apps where retention is the key metric.
• Product teams who care about cohort analysis depth.
• Apps at scaling stage (post-launch, pre-Series A).

PostHog

Strengths

• Open-source. Self-host for full data ownership.
• All-in-one platform: analytics + feature flags + A/B testing + session replay.
• Generous free cloud tier.
• Predictable pricing when self-hosted (only your infra costs).

Weaknesses

• Self-hosting overhead if you go that route.
• Less mature mobile-specific docs vs Mixpanel/Amplitude.
• Smaller community for mobile use cases (PostHog is web-heavy).

Pricing (2026)

• Cloud free: 1M events + 5k recordings/month.
• Cloud paid: usage-based, often cheaper than Mixpanel/Amplitude at scale.
• Self-hosted: free + your infra cost.

Best for

• Privacy-conscious teams (self-host).
• Teams that want analytics + A/B testing + feature flags in one tool.
• Indie devs who outgrow free tiers and want predictable pricing.

Firebase Analytics

Strengths

• Free forever.
• Tightly integrated with Google ecosystem (Crashlytics, Cloud Messaging, Remote Config).
• Good enough for basic tracking.

Weaknesses

• Limited cohort analysis vs paid tools.
• Event limits can be restrictive for complex apps.
• Reporting interface less polished than Mixpanel/Amplitude.

Pricing

Always free for core analytics.

Best for

• Earliest-stage apps just getting started.
• Apps already heavily using Firebase (Cloud Messaging, etc.).
• Backup or supplementary analytics alongside Mixpanel/Amplitude/PostHog.

Feature comparison

Decision matrix

Stage / Need              Recommend
----------------------------------------
Pre-launch / indie         Mixpanel free tier
Subscription app launch    Amplitude free tier
Self-host / privacy        PostHog
Already on Firebase        Firebase + supplement
Mobile B2B                 Amplitude (cohort depth)
Cost-conscious at scale    PostHog
First experience           Mixpanel (easiest docs)

Migration cost

Switching analytics tools requires:

1. SDK swap in your app.
2. Event-name remapping.
3. Historical data is lost (unless you export carefully).
4. Re-building dashboards.

Plan 1-2 weeks to fully migrate. Pick early, stick with it unless really unsatisfied.

What to track from day 1

Regardless of tool, instrument these events at minimum:

app_open
onboarding_step_1_complete (through N)
first_value_action
paywall_seen
trial_started
trial_paid_conversion
subscription_renewed
subscription_canceled
feature_used (with feature name)
session_end
crash_occurred (handled by Crashlytics/Sentry)

Plus user properties:

user_id
acquisition_source (organic, search-ads, meta, tiktok, google-ads)
country
device_class (iphone, ipad, pixel, samsung)
app_version
locale
subscription_status (free, trial, paid)

These cover 80% of typical analyses.

What NOT to track

• Every UI interaction. Tap-level tracking explodes event volume and rarely informs decisions.
• PII (email, phone) — analytics tools aren't the right store.
• Anything that can identify a single user uniquely without consent (privacy compliance).

Common mistakes

• Tracking nothing. Most common mistake. Even Firebase free tier is better than nothing.
• Tracking everything. Explodes events. Track meaningful actions only.
• No user property setup. Can't segment cohorts effectively.
• Inconsistent event naming. Mixed snake_case, camelCase, abbreviations.
• No integration with subscription tool. Mixpanel/Amplitude + RevenueCat is essential for subscription apps.
• Picking the most expensive tool prematurely. Indie scale doesn't need enterprise plans.

Pair with subscription analytics

For subscription apps, your analytics tool sits alongside your subscription tool (RevenueCat / Adapty / Apphud). They should integrate. See RevenueCat vs Adapty vs Apphud.

Common stack:

Subscription state: RevenueCat
Product analytics:  Mixpanel
ASO audits:         ASOhack
Crash reporting:    Crashlytics or Sentry
Push:               OneSignal or Firebase Cloud Messaging
Attribution:        SKAN direct + per-network dashboards (or MMP at scale)

For most indie apps, this stack is $0-$25/month and covers everything.
