Device cohorts
A product can look healthy overall while a device model, platform, OS version, or app version quietly carries lower engagement, longer sessions, crashes, ANRs, or rage taps.

From signal to answer
Device-specific friction hides inside average product metrics
2. Issue pressure
Issue pressure
Rejourney's device insights show the device portfolio, platform mix, engagement leaders, issue pressure, and device-version hotspots so teams can find friction that averages hide.
3. Engagement quality
Engagement quality
When device data stays connected to replay and stability context, engineering can reproduce issues faster and product can avoid treating a device-specific problem like a broad UX failure.

FAQ
Questions, answered.
What do device insights show?
They show which devices, platforms, app versions, and device-version combinations carry session volume, engagement, duration, crashes, ANRs, errors, and other issue pressure.
Why does device analytics matter for mobile apps?
Mobile issues often appear only on certain devices, operating systems, or app versions. Device analytics helps teams find those pockets before they distort retention or support volume.
Can device insights connect to replay?
Yes. Rejourney keeps device and stability context near replay evidence so teams can inspect the sessions behind device-specific friction.
