Mobile analytics software helps developers understand how users interact with their apps by tracking events, sessions, and conversions. The best solution depends on your specific needs: feature depth, platform support, and how much user data you want to collect. This guide compares the leading options.
📊 What is Mobile Analytics Software?
Mobile analytics software (also called in-app analytics or app analytics tools) tracks how users interact with mobile applications. These platforms collect event data—button taps, screen views, purchases, feature usage—and provide dashboards for analyzing user behavior.
Common capabilities of mobile analytics software include:
- Event tracking: Record specific user actions (e.g., "add_to_cart", "complete_purchase")
- Funnel analysis: Visualize conversion paths and identify drop-off points
- Retention metrics: Measure how often users return to the app
- User segmentation: Group users by behavior, attributes, or cohorts
- Real-time dashboards: Monitor current activity and trends
The platforms differ significantly in what data they collect, how they store it, their pricing models, and the depth of analysis they provide.

1️⃣ Firebase Analytics (Google Analytics for Firebase)
Firebase Analytics is Google's mobile analytics platform, tightly integrated with the Firebase suite of development tools. It's free with unlimited events, making it the default choice for many developers.
✓ Strengths
- Free to use with unlimited events
- Deep integration with Firebase services (Crashlytics, Remote Config, Cloud Messaging)
- BigQuery export for custom analysis
- Automatic event tracking for common interactions
- Google Ads integration for attribution
⚠ Considerations
- Collects device identifiers by default — Instance ID and IDFV are personal data under privacy regulations, requiring disclosure and potentially consent
- IP addresses processed for geolocation — IP is personal data; you need to document this processing in your privacy policy
- Data may be used for ads personalization — Unless explicitly disabled, this creates additional disclosure obligations
- Privacy-friendly setup requires configuration — Default settings collect more data; you must actively configure limits
- App Store Privacy Label complexity — Device identifiers require "Data Linked to You" disclosures
Data collection note: According to Firebase documentation, you can disable analytics collection temporarily or permanently, disable IDFV collection, and control ad personalization. However, these require explicit configuration.
2️⃣ Mixpanel
Mixpanel is a product analytics platform known for its powerful funnel analysis, retention reports, and user segmentation capabilities. It's popular among product teams who need detailed behavioral insights.
✓ Strengths
- Advanced funnel and retention analysis
- Flexible user segmentation and cohorts
- Real-time event stream
- Good documentation and SDKs
⚠ Considerations
- Persistent distinct_id across sessions — This is personal data that enables long-term user tracking, triggering data subject rights obligations
- $device_id merges with $user_id — Pre-login activity gets linked to identified users via "ID clusters," expanding the personal data you hold about each user
- Custom properties accept any data — Developers can accidentally send PII (emails, names) in event properties, creating unintended data collection
- Pricing scales with data volume — Not a privacy issue, but costs can grow unexpectedly
Data collection note: Mixpanel's documentation states they've built tools for GDPR and CCPA compliance including deletion APIs, opt-out methods, and data export. They offer autocapture with privacy controls to omit input elements by default.
3️⃣ Amplitude
Amplitude is an enterprise-focused product analytics platform with advanced features for behavioral cohorts, experimentation (A/B testing), and user journey analysis. It's commonly used by larger product teams.
✓ Strengths
- Behavioral cohort analysis
- Built-in experimentation and feature flags
- Session replay (Amplitude Plus)
- Data governance tools and TTL settings
⚠ Considerations
- Tracks deviceId by default — Persistent device identifiers are personal data, requiring disclosure and potentially consent
- IP addresses captured client-side — Personal data that must be documented; disabling requires explicit configuration
- Cross-domain tracking capability — Enables tracking users across different websites, which may require additional consent disclosures
- MTU-based pricing — Not a privacy issue, but enterprise costs can be significant
Data collection note: Amplitude's documentation includes guidance on Time to Live (TTL) for data retention, opt-out methods, IP address controls, and a User Privacy API for deletion requests. They provide Apple Privacy Manifest guidance for iOS SDK.
4️⃣ PostHog
PostHog is an open-source product analytics platform that combines event tracking, session replay, feature flags, and A/B testing in a single platform. It can be self-hosted or used as a cloud service.
✓ Strengths
- Open-source with self-hosting option
- All-in-one: analytics, session replay, feature flags, A/B testing
- EU hosting available
- Autocapture with privacy controls
⚠ Considerations
- Person identification and cross-session tracking — Persistent user profiles are personal data with associated rights obligations
- GeoIP enrichment processes IP addresses — Even if you only store country, IP processing must be documented
- Self-hosting requires infrastructure work — You gain data control but take on operational and security responsibilities
- Feature-rich platform — More capabilities means more configuration decisions and potential data collection points
Data collection note: PostHog's documentation describes cookieless tracking options, session replay masking for sensitive data, and custom apps for privacy controls (such as country-only geolocation). Self-hosted deployments give full data control.
5️⃣ Respectlytics
Respectlytics takes a fundamentally different approach: instead of collecting data and then managing privacy, it avoids collecting personal data in the first place. Built around the Return of Avoidance (ROA) philosophy, it stores only 5 fields per event while still providing automated conversion intelligence to discover user behavior patterns.
✓ Strengths
- Strict 5-field architecture: event_name, timestamp, platform, country, session_id—nothing more
- No data deletion workflows needed: No personal data stored means no deletion requests to handle
- Defensible by design: API rejects extra data, so developers can't accidentally collect PII
- Simple privacy posture: Straightforward to explain, audit, and defend
- Clean App Store Privacy Label: "Data Not Linked to You" with minimal categories
- Automated conversion intelligence: Discovers funnels and drop-offs without manual configuration
- Session-based insights: Still get feature adoption, conversion rates, and engagement patterns
⚠ Trade-offs
- No cross-session user tracking (by design)
- No cohort retention analysis (no persistent user IDs)
- No custom properties (by design—prevents PII leaks)
The Return of Avoidance (ROA) Philosophy
Traditional analytics platforms let you collect anything—then you manage privacy afterward. Respectlytics inverts this: the strict 5-field architecture means you can't accidentally collect personal data through custom properties. The result is analytics that's transparent (clear about what's collected), defensible (minimal data surface), and simple (no data deletion workflows to maintain). You still get conversion funnels, feature adoption metrics, and drop-off analysis—just without the ongoing privacy management burden.
🔒 Data Collection Comparison
Understanding what each mobile analytics software collects is critical for privacy considerations and App Store compliance. Here's a comparison based on default configurations:
| Data Type | Firebase | Mixpanel | Amplitude | PostHog | Respectlytics |
|---|---|---|---|---|---|
| Device IDs | Default | Supported | Default | Supported | None |
| IP Address Storage | Processed | Optional | Default* | GeoIP App | Transient only |
| Custom Properties | Unlimited | Unlimited | Unlimited | Unlimited | Blocked |
| Persistent User IDs | Yes | Yes | Yes | Yes | No |
| Cross-Session Tracking | Yes | Yes | Yes | Yes | No |
* Can be disabled via configuration. Check each platform's documentation for current options.
⚠️ Important Note on Custom Properties
Custom properties are powerful but risky. Developers can accidentally log email addresses, phone numbers, or other personal data in custom event properties. Respectlytics blocks custom properties at the API level to prevent this risk entirely.

💡 The Hidden Cost of Personal Data in Analytics
When analytics platforms store device IDs, user IDs, or IP addresses, you take on ongoing obligations:
- Data deletion workflows: You need engineering time to build, test, and maintain deletion request handling via each platform's API
- Response time requirements: Privacy regulations often require responding to deletion requests within 30 days
- Audit trail maintenance: You need to prove deletions were completed across all systems
- Ongoing vigilance: Custom properties can accidentally capture PII if developers aren't careful
Respectlytics sidesteps this entirely. With session-based analytics and no personal data storage, there's nothing to delete—and you still get actionable conversion insights.
