State of Mobile App Quality 2018


What data did we analyze?

This report covers six years of our data, from when Instabug was founded in 2012 and through our journey to reach one billion devices. No personal data was analyzed.

In the charts that follow, you will see "bugs", which represents the total count of bugs in pre-production (beta) and production (live) apps, and "bugs/user", which represents those bugs normalized by the number of app testers and end users who reported those bugs. We show you both so that you can understand the volume of absolute bugs reported through Instabug, as well as their weight relative to the amount of users who experienced those bugs.

In the line charts, you will also see our raw data, represented by dark blue lines, and smoothed data, represented by blue trend lines. Smoothing the data filters out noise, anomalies, and fine-scale differences, showing you the important patterns in the data.
