Mobile apps are more important to business growth than ever before because
they are powering an increasing number of customer interactions. Users have high expectations from
their mobile apps, like stability, speed, and availability of new capabilities and
To help you understand how your app compares to other leading mobile apps, BugSnag has compiled benchmarks including an analysis on how stability impacts app store ratings, and industry trends for stability and release frequency. We invite you to explore them.
Mobile app stability
can be impacted by factors such as the value and volume of user interactions. As a
key indicator of user experience, app stability is a vital business metric encompassing conversion,
engagement, and retention, all of which are tied to revenue and business growth. That’s why leading
engineering organizations across industries are actively working to manage and improve their app
Stability is a percentage of app sessions that are
crash-free. Stability scores are used to gauge app health and user experience.
Overall Median of Apps Analyzed
For mobile apps to lead the market and stand at the forefront of business growth,
companies should execute on the following insights.
The more 9s in an app’s stability score, the higher the app store
There is a tradeoff between the value of the interaction, customer
loyalty, and app stability. The value of the interaction may be the strongest predictor
of app stability.
Weekly releases are replacing the bi-weekly norm as apps are being
updated more frequently.
The nines of stability are similar to the five-nines that
infrastructure and operational teams use to measure uptime and availability. More nines in a
stability score indicate more stable app experiences.
Users rate apps on
the Google Play and Apple App Stores based on their overall experience. Depending on the type of
app, some factors weigh heavier than others. Examples include usefulness, design, engagement, and
stability. Analyzing app store ratings for different stability cohorts provides insight into how
stability impacts user experience.
Apps that achieve more 9s in their stability score have higher app store
ratings. This demonstrates how apps that are more stable drive more exceptional user
experiences, maximize retention, and build competitive advantage.
Frequently occurring stability issues and bugs disrupt an app experience
and can motivate users to submit a lower rating. This explains the wider spread of ratings and
the lower median app store rating for apps with a stability of less than 99%.
Depending on the
industry, different factors have varying effects on stability. Understanding these factors will help
engineering organizations develop effective strategies for delivering higher quality apps.
Trailblazers: For just one important task, you need this app.
B2B SaaS apps, which generally have fewer and higher paying users
compared to B2C SaaS apps, have a higher median stability. It is costlier to attract
customers and thus more important to retain them with stable app experiences.
eCommerce, Travel & Hospitality, and Finance & Banking
apps, whose users open the app with the intention to spend or manage money, need to
maintain a higher stability because crashes directly impact revenue.
Old Faithfuls: It does the job, but there’s room for
B2C SaaS/Consumer Mobile, Consumer Goods, and Health & Wellness
apps have loyal users. When faced with app stability issues, they are slower to switch
to a competitor. These apps can afford to balance stability initiatives with other
A Dime a Dozen: If you don’t like it, there are plenty of
Mobile games can attract millions of users, but these users can be
less loyal, and retaining them requires consistent engagement like updating games
frequently with new content and game modes. Frequent code changes can introduce more
bugs, explaining the lower median stability score and wider spread of scores for the
Media & Entertainment apps also serve a mass market and tend to
have lower ARPU (Average Revenue Per User), making it essential to deliver new
capabilities often. Many in the industry who have not historically been
technology-driven are quickly building their mobile streaming initiatives in an attempt
to remain competitive.
This research cohort also shows that apps are falling short of the four 9s of
apps to deliver new features and address software bugs. Understanding how frequently high
stability apps release a new version can help development teams benchmark their app’s release
cadence and decide if it needs to be adjusted to boost retention.
Our research shows that leading mobile apps have shifted to a 1x per week release cadence compared to a previously popular trend of 1x per two weeks.
Based on 4x / 30 days
Release frequency measures the number of times an app
updates to a new version within a 30-day time span.
Bi-weekly releases were once the norm, but data across industries indicates
that apps are being updated with a new version more frequently.
Data on more frequent releases proves that more and more engineering
organizations have adopted CI/CD and automated their deployment pipelines to ship new versions
Approaches like release progressions and feature flags
are helping teams build more confidence in developing and shipping new features to users
Usage of eCommerce apps surged during the COVID-19 pandemic, and that may explain why
they are updated more frequently with new capabilities and bug fixes.
