Creating an app is exciting. Seeing the first downloads happening is magical. But soon after comes the question: "Are they enjoying it? Where are they clicking? Why are they uninstalling?".
If you are new to the world of applications, the term "Analytics" may seem daunting, full of complex graphics and English terms. Calm. Analytics is just a fancy way of saying “paying attention to what users do.”
This is a step-by-step guide, free from complicated jargon, for you to implement your first data analytics strategy in a mobile app.
Step 1: Choose Your Tool (Weapon)
Don't try to build your own analysis system. Use what the market offers. For beginners, the recommendation is almost unanimous: Google Analytics for Firebase.
- Why?: It's free, unlimited, made by Google (integrates natively with Android and well with iOS) and is the industry standard.
- Alternatives: Mixpanel (best for funnels, has a limited free plan) or Amplitude.
Action: Create a Firebase Console account, register your app, and ask the developer to install the Firebase SDK. It's fast.
Step 2: Define “Success” (Key Events)
Firebase collects some things automatically (like "app_open" or "first_open"), but it doesn't know what's important to YOUR business. You need to teach.
List the 3 most important actions a user can do in your app. Examples:
- Complete the registration (
sign_up). - Watch a video (
video_completed). - Buy an item (
purchase).
Action: Define these names. Use lowercase letters and underline (ex: adicionar_carrinho). Ask the developer to put the code that "triggers" this event when the action happens.
Step 3: Understand the Conversion Funnel
Imagine a leaky bucket. You throw water (users) on top, but the water leaks through the holes before reaching the bottom. The funnel helps to find the holes.
Create a sequential view in your Analytics:
- Opened the App
- Clicked on "Register"
- Filled in the data
- Confirmed the registration
If 100 people open the app, but only 10 confirm their registration, you have lost 90% of users in minutes. Where? If 80 people click on register, but only 20 fill in the data, the "hole" is in the form. Maybe it's too long or difficult.
Action: Set up a "Funnel" in Firebase with your top events.
Step 4: Retention (The Truth Metric)
Forget the total number of downloads. This is a “vanity metric.” The metric that tells you whether your app is good is Retention.
Go to the Retention tab and look at the cohort graph.
- Day 1: How many % of people who downloaded yesterday opened the app today?
- Day 7: How many returned after a week?
If your Day 1 retention is below 20%, stop spending money on marketing. You need to improve the product (the app) first. No one wants to go back to a bad restaurant, no matter how much advertising it does.
Step 5: Use Data to Improve (Iteration)
Analytics are not just for looking; serves to act.
- Scenario: You saw in Step 3 that many people give up on the registration screen.
- Hypothesis: "If I put the option 'Log in with Google', it will make it easier."
- Action: Implement social login.
- Measurement: Wait two weeks and look at the funnel again. Did the conversion go up? If so, congratulations! You used data to improve your app.
Golden Tips for Beginners
- Less is More: Don't try to track everything (every click, every scroll). You will drown in useless data. Start with 5 to 10 main events.
- Test Before: Before launching, open the app in "Debug" mode and see if the events are appearing on the panel in real time. It's horrible to find out after a month that the purchase event wasn't being counted.
- Segment: Do iPhone users behave the same as Android users? Do users who came from Instagram act the same as those who came from Google? Use filters to compare.
Conclusion
Analytics for apps is a superpower. It gives you X-ray vision. Instead of guessing what users want, you watch what they do.
Get started today. Install the SDK, define your core events, and start hunting for the "holes" in your bucket. Your app (and your pocket) will thank you.
