Ever wondered why the number of people using your app suddenly dropped? Or why your app isn’t generating as much revenue as you thought it would? Blind guessing will not help. But if you implement an analytics tool in your app, the answer could be revealed to you quickly and effectively. Just like analytics tools for websites, app analytics solutions track a huge number of metrics that help you to understand the behavior of your users and to improve your app accordingly. But with so many available, it can be difficult to know where to start. We take a look at nine of the top app analytics tools.For ease of use, we will only be looking at analytics platforms that work for both iOS and Android apps, and that are available to use without paying hundreds of dollars a month. 1. Firebase Firebase is Google’s free, unlimited mobile app analytics solution which provides all the tools you need to improve your app and grow your user base in one place. Once installed, it will automatically start collecting data on insights such as who your users are, how much time they spend using the app and how much revenue they have generated. This is just the tip of the iceberg. Google includes 500 distinct events that you can use to drill down into your users’ behavior which will help you to improve your app as a result.Price: Free for unlimited use 2. Fabric Fabric is a real-time mobile analytics platform that combines an intuitive dashboard with events tracking, crash reporting, payments tracking, growth reports, user segmentation and more to deliver an all-in-one solution. Acquired by Google in January of this year, Google will continue to run the platform alongside Firebase.Price: Free 3. MixPanel MixPanel is another great, all-in-one option that lets you easily track assigned events, create user funnels so you can see the journey of your users at a glance and carry out A/B testing to help you improve the performance of your app. All of this data can be displayed in dashboards and in charts which can be as simple or as detailed as you like. The platform comes with a free mobile app that sends custom alerts to your smartphone.Price: Free to track up to 25,000 data points per month 4. Flurry Flurry is the analytics solution from Yahoo! that is used by over 800,000 apps. Like the previous platforms, you can track events, create user funnels, segment your audience by demographic and interests, and track ad performance. It can be used on apps for Blackberry smartphones, as well as Android and Apple phones, and has unlimited free use. With this free app, all of your app’s metrics are available on your own phone anywhere, at any time.Price: Free 5. Countly Countly provides a 360-degree view of your customers’ journeys through your app. Similar to the other solutions, it offers a suite of tools that will enable you to track events, user retention, advertising performance, user journeys and crashes. The only downside with this solution is the price tag. It is free to use for non-commercial apps, but using it for any business-related app will require you to purchase the Enterprise Edition which starts at $250 per month.Price: Free for non-commercial use / $250 per month for Enterprise 6. Amplitude Amplitude’s analytics offering focuses on user behavior to help you to improve your app, rather than other vanity metrics. It is easy to install and will let you track things such as drop-off points in your conversion funnel, retention drivers and detractors as well as customer journeys.Price: Free for up to 10 million monthly events 7. Apsalar Unlike the other apps discussed so far, Apsalar focuses on improving the return on investment (ROI) of your app through effective advertising. It still provides all of the tracking features you’d expect, but the focus is on making your advertising and marketing campaigns as profitable as possible. Unfortunately, Apsalar puts a two-year cap on data retention, so it may not be the best choice for long-term projects.Price: Free 8. Appsee Appsee is another all-in-one platform that lets you track a huge range of events, understand your audience better, and optimize your A/B tests. What separates Appsee from the other solutions listed here, however, are some of the features provided. Appsee lets you record users and provides touch maps so you can understand exactly how your users use the app and the problems they are experiencing. Unfortunately, these extra features mean Appsee is not available for free. Still, there is a 14-day free trial that will give you a taste of the platform.Price: 14-day free trial. After the trial, pricing will depend on number of platforms and estimated number of events per month. 9. Localytics Localytics provides all of the user insight data you could need (session tracking, retention rates, funnels and user profiles) but the focus here is on marketing. Localytics lets you reach your users with highly target campaigns that utilize push notifications, in-app advertising, personalized messages and A/B testing. Price: Free for up to 10,000 eventsSo, use one of these tools to optimize your app and expand your digital footprint. If your app is live, every second you waste without analytics is costing you data that could be used to improve your app. If you don’t know which to choose, start by installing Firebase and go from there.
