Clarity for Mobile Apps Overview
What is Clarity Mobile SDK?
The Clarity SDK for Android allows you to capture essential information about user interactions with all parts of your app. This can help you replay user sessions, view heatmaps, and monitor key application signals via the metrics dashboard. Integrating Clarity SDK into your mobile application requires minimum development effort.
Clarity Mobile SDK uses innovative technology to reconstruct user sessions by capturing low-level drawing commands to create a walkthrough-style video. This technology has minimal effect on network consumption and creates nearly perfect session replays.
How does Clarity Native Android SDK work?
Once the SDK is integrated and initialized, it starts capturing data. The captured data include:
- User screens/visuals to recreate user sessions.
- User interactions (taps, double taps, touches, ...etc.)
- Captured data buffers on the mobile device and is periodically uploaded to Clarity's servers if the device is connected to the internet. The default configuration for Clarity is to send data over an unmetered network. However, this setting also can be changed.
Note
The data might take 30 minutes to 2 hours to show up on the dashboard.
Supported Features
The following features help you identify user requirements by allowing you to study user behavior:
- Session Recordings
- Heatmaps
- User interaction insights such as Rage taps, Dead taps, Taps, and Double taps.
Important
- System dialogs aren't captured.
- Notifications, navigation bars, and the keyboard are external components of the app and are not captured.

Performance
The Clarity Mobile SDK is designed to be lightweight with minimal performance impact on your app.
Main Thread Usage
The Main (UI) thread usage by Clarity highly depends on the nature of your application. Testing on a representative set of applications and device configurations produced the following results.
Key results:
Note
These numbers may vary across users' sessions or apps.
| Results | Performance |
|---|---|
| Clarity initialization time | 3-5 ms |
| Percentage of increase in frame time at P95 | 3-5% |
Bandwidth Usage
On unmetered networks, the SDK streams the recording data directly to Clarity's servers. You can expect to see around 10 KiB (per second of recording) going to Clarity. If your app is image/graphics-heavy, it may experience higher outgoing traffic at first due to asset uploading.
Disk Usage
Clarity buffers the data on the disk before sending it. The data is written to temporary storage that the OS can retrieve later when needed. Moreover, the SDK deletes the data periodically.
Size
The Clarity Android SDK increases your APK download size by around 400 KB.
