Contentsquare vs. Amplitude vs. Fullstory: which is best for mobile and app analytics?

The information on this page is correct as at 27/05/2026 to the best of Contentsquare's understanding.

Most mobile analytics tools force you to choose between quantitative depth and behavioral context. Amplitude gives you the numbers, but only for events you remembered to tag. Fullstory captures more behavior, but buries mobile behind an enterprise paywall. Neither gives you a clear understanding of what’s happening on your mobile app, why it’s happening, and exactly where to focus next to drive growth. 

And, unless you're an app-only company, mobile analytics rarely live in a vacuum. The real value comes from understanding mobile in the context of the full customer journey alongside web, support, and every other touchpoint where users meet your brand.

Contentsquare (which now includes Heap, hello! 👋) gives you the complete picture: every tap, swipe, and scroll captured automatically, connected to the full cross-device (and offline) journey, with advanced AI that surfaces friction, quantifies impact, and prioritizes what you need to work on next. 

Here's a closer look at how Contentsquare, Amplitude, and Fullstory compare for mobile and app analytics, and why we’re confident that Contentsquare is the best choice for turning mobile data into business growth.

Key takeaways

• Amplitude delivers strong quantitative mobile analytics (including funnels, cohorts, and retention curves) but it relies on manual tracking for business-critical events. If you forgot to track something, that data is gone forever. It also lacks clear ways to visualize mobile behavior, like mobile app heatmaps

• Fullstory has high-fidelity session replay and autocapture, but mobile app analytics sit behind an enterprise paywall as a separate add-on. Even with full access, Fullstory is better suited to replay-first troubleshooting than macro-level visualizations

• Only Contentsquare combines complete autocaptured mobile analytics with experience intelligence that reveals the why behind every behavior, connects mobile to the full customer journey across devices (and offline), and catches issues before users churn—all powered by a shared AI layer that surfaces friction and quantifies impact automatically, giving every team the full picture of mobile performance and a clear path to growth

• That's why Contentsquare delivers 602% ROI and $3.2M in recovered revenue over three years, according to a Forrester Total Economic Impact™ study, compared to Fullstory’s 451% and Amplitude’s 217%

How Contentsquare vs. Amplitude vs. Fullstory compare for app analytics

Mobile analytics features tend to look similar on paper: retention charts, session replay, AI agents. If you only compared features, you’d never make a decision. 

Instead, consider how you’ll use the platform, like: What happens when you forget to tag something? Who on your team can actually use the data? And can you connect what a user did in your app to what they did on your website an hour later?

Use the below table to see how Contentsquare vs. Amplitude vs. Fullstory compare in terms of the popular questions your team needs to answer about mobile experience and performance.

What Contentsquare, Amplitude, and Fullstory do differently (and what to ask to find out)

Contentsquare, Amplitude, and Fullstory all provide basic mobile event analytics, funnels, and session replays. Those are all useful features, but when you’re choosing a platform for mobile growth, you need to think beyond cookie-cutter dashboards and tools and think about what’s going to give your team an edge over competitors. 

Here are the three main questions to consider when choosing the right platform to drive mobile growth.

Is your mobile data complete enough to act on?

Mobile analytics data is only valuable to the business if it can be relied on to tell you what’s happening, why users are taking action (or bouncing), and what to do next to drive growth. 

For that, you need complete data: every screen, every tap, every flow, captured and analyzed without excessive engineering resources or worrying about missing insights. 

Amplitude is the weakest here because even with recently added limited autocapture, business-critical events like revenue transactions and custom user properties still require manual setup. You need to plan every tracking event at the start and then have to maintain your setup and check tracking is working when things change (which can be often). If, in the future, you find an interesting mobile behavior you want to dig into that wasn't tracked, that data is lost forever and there’s nothing you can do to get it back. 

Fullstory is better than Amplitude for data completeness because it has autocapture analytics they call ‘Fullcapture™’, which is essentially a server-side script that automatically tracks all events. However, Fullstory’s mobile autocapture is heavily limited by what plan you’re on (mobile app support is an enterprise-tier feature, priced as a separate add-on) and many reviews state that the setup process is complex, which could become a blocker for non-technical teams.

Contentsquare’s Smart Capture collects every interaction on your app and website from day one

Contentsquare improves on Amplitude and Fullstory’s mobile offerings with easy-to-install, complete mobile data tracking, from day one (even on our free plan):

• We have the best web and mobile autocapture analytics on the market (Smart Capture), proven over +10 years (thanks to our acquisition of Heap)

• Use our lightweight client-side SDK to deploy quickly across iOS, Android, React Native, and Flutter and start gaining insights immediately with mobile-specific, out-of-the-box dashboards and reports

• Retroactively analyze any mobile or cross-device pattern anytime

• Keep dashboards clean with robust data governance features, including a data dictionary, naming conventions, and visual labeling

Contentsquare measures every app install and what users do next from day one

In short, choosing Contentsquare over Amplitude and Fullstory means your mobile data is complete, trustworthy, and ready to act on from the moment you install the SDK.

"With Smart Capture, if I forgot to track it, CSQ tracked it anyway. If I get a question two months later, I never need to worry—because the data is there.” - Matthew Gomes, Director of Marketing at OppLoans

Of course, even complete mobile data collection is only useful if your platform can go beyond just reporting on what’s happening and give you the full picture of your mobile experience, which brings us to question number two:

Do you see the experience or just the numbers?

Knowing that 60% of users dropped off during onboarding is useful. Knowing exactly which element(s) confused them, how long they hesitated, and what it cost you in revenue is what actually lets you fix it. 

And for that, you need to choose a platform that shows you the full experience behind the numbers, not just a bunch of unconnected mobile usage charts.

Amplitude gives you strong quantitative depth: funnels, cohorts, retention curves, and behavioral segmentation. But (assuming you’ve set up your tracking perfectly and nothing ever changes in your UI), Amplitude is not designed for mobile experience analytics.

Choose Contentsquare over Amplitude for mobile app heatmaps—use them to see what drives app engagement

Fullstory is stronger than Amplitude on the visual experience side thanks to its high-fidelity session replay tool, but it’s not designed for comprehensive mobile-app analytics. That’s probably why they’ve siloed mobile analytics as an optional add-on.

Choose Contentsquare over Fullstory for connected mobile app feedback—use it to find friction and opportunities to improve retention

With Contentsquare, your team gets the numbers and the full experience behind them, all connected to real business impact:

• Understand exactly how your app is performing: track retention, funnels, feature adoption, user acquisition, and engagement with complete Mobile App Analytics across every mobile audience and cohort

• See how users interact with your app: use Mobile Heatmaps and Session Replay to visualize where users tap, scroll, and hesitate, and watch exactly how individual users navigate your app to spot friction, confusion, and bugs in context. Select any element to view exact tap counts so you know what drives engagement (and what people skip)

• Understand what mobile users are actually thinking: use Voice of Customer tools to collect behavior-triggered in-app feedback and run user tests and interviews, connected directly to replays so you know exactly what users experienced before they shared their opinion

Choose Contentsquare for all-in-one mobile insights

• Measure the business impact of push notifications: understand what type of notifications re-engage users the most, and which drive conversion and retention

• Understand cross-device and cross-channel journeys: visualize complete journeys from your app to your website and back, identify dropoffs, and bring offline events like in-store purchases or physical touchpoints into the analysis

• Catch and fix app issues before they cost you users:detect crashes, API errors, and slow screens with Experience Monitoring and calculate their exact impact on mobile behavior and revenue

• Quantify the impact of mobile experience: use Impact Quantification to see exactly how any screen, interaction, or error affects conversions and revenue

Choose Contentsquare to get the complete picture behind your app: what users did and why

In short, Contentsquare covers the full mobile experience by combining what users did, why they did it, and what it’s costing you, in one place.

Now you know what the full mobile experience looks like in practice, the next question is whether your platform of choice will leave you drowning in all that data or help your team make sense of it all.

How easily can your team turn mobile insights into action?

You don’t want a mobile analytics platform that just dumps data into dashboards: you need one that guides your team to action, saving time and reducing manual errors along the way. 

And that’s where AI features and workflows become important. 

Amplitude has AI agents that automate analysis, build dashboards, and recommend app optimizations. But it's severely limited by what was tracked: if the data isn't there, the AI can't help you fill in the gaps.

Fullstory has StoryAI, which also has agentic capabilities to proactively find opportunities. But it’s heavily influenced by Fullstory’s focus on front-end interactions and session replays.

Contentsquare’s AI, Sense is designed to surface what matters most on mobile, automatically:

• Query your mobile data in plain language: ask Chat with Sense anything, like ‘Why did mobile conversions drop yesterday?’ and generate the right charts and recommendations in seconds

• Run expert mobile analysis on autopilot: Sense Analyst pulls data from across your mobile experience (like Heatmaps, Mobile Analytics, and Feedback) and tells you exactly what’s happening and what you need to do next. Just ask it a question or select a use case like ‘reduce mobile churn’ and it does the rest

Contentsquare Sense Analyst gives every team expert-level mobile analysis on autopilot

• Spot where mobile users are struggling: Frustration Score automatically detects rage taps, repeated actions, and hesitation signals across every screen

• Get notified when something changes: set up AI and manual Alerts to automatically flag significant shifts in mobile behavior, conversion rates, or error rates

• Understand any mobile audience without writing SQL: Smart Segmentation lets you filter behavior by device, channel, campaign, or audience in seconds

• Turn mobile feedback into action:AI-powered Voice of Customer analysis generates survey questions, tags open text feedback, analyzes sentiment, and connects it to replays and quantitative datapoints

• Make sense of every customer conversation: Conversation Intelligence analyzes support chats, calls, and emails at scale, connecting what mobile users say to what they did in the app

• Bring mobile insights into your existing workflows: use the Contentsquare MCP server to pull mobile insights directly into your favorite AI agent (like Claude or ChatGPT) and get updates where you work (like email, Slack, MS teams)

Final take: the best mobile analytics platform for complete data, fast answers, and real business impact

Amplitude and Fullstory are capable mobile analytics tools, but both force you to accept trade-offs that limit your team's ability to drive mobile growth.

Amplitude gives you quantitative depth, but only for the events you remembered to track. If your tracking plan has gaps (and it will), so will your insights. Fullstory is stronger on behavior insights, but the platform is focused on replay-first issue troubleshooting. And mobile app features sit behind a premium enterprise add-on, putting them out of reach for most growing teams.

Only Contentsquare gives you 360 experience intelligence across the full mobile journey, from first tap to support chat. You get complete cross-device data from day one. Sense AI analyzes trends and finds opportunities for you so every team can act fast and prove their impact without technical training or ongoing engineering resources. 

That's why we drive 602% ROI and $3.2M in recovered revenue over three years, and are trusted by +3,000 enterprise and mid-market brands, including the mobile teams at Alo, Leonardo.ai, and John Lewis & Partners.
