+<h3>
+  Background
+</h3>
+
+<p>
+  Aftenposten is one of the largest newspapers in Norway. Their <a class=
+  "external-link" href=
+  "https://play.google.com/store/apps/details?id=no.cita&amp;e=-EnableAppDetailsPageRedesign">
+  news app</a> was released on Android in 2013.
+</p>
+
+<p>
+  Aftenposten found that sending too many notifications, with no user control
+  over the default <em>on</em> setting or differentiation between general and
+  breaking news, caused many people to uninstall their app. They changed the
+  user controls for notifications and used the native Android share button in
+  the app, <strong>which reduced user uninstalls</strong>.
+</p>
+
+<h3>
+  What they did
+</h3>
+
+<p>
+  Aftenposten created a new onboarding flow that explained what notifications
+  were available, allowing readers to manage their preferences and customize up
+  to three topics. They also changed their custom share icon for the native
+  Android app.
+</p>
+
+<h3>
+  Results
+</h3>
+
+<p>
+  The results showed that with the new notifications management onboarding
+  screen, <strong>uninstalls decreased by 9.2% over 60 days</strong>. And with
+  the option to customize notifications, 51% of readers decided to keep two out
+  of three topics turned on. This led to a <strong>28% decrease over 60 days in
+  the number of users muting notifications completely</strong>. It also
+  provided insight into users’ content preferences, with <em>Sport</em> being
+  the least-favored notification.
+</p>
+
+<p>
+  Aftenposten also increased share interactions by 17% just by replacing their
+  custom share icon with the native Android share icon.
+</p>
+
+<p>
+  Aftenposten commented that: <em>Many of our users who see the onboarding
+  screen interact with it by turning off at least one notification topic. This
+  means that users are accepting push from one or more topics, instead of
+  turning it off completely. Moreover, readers are sharing more articles since
+  we added the standard share Android icon.</em>

+  rating and improve user engagement.
+</p>
+
+<h3>
+  What they did
+</h3>
+
+<p>
+  El Mundo decided to completely redesign their app to provide a higher quality
+  user experience, making it easier for their readers to engage with news
+  content. By implementing material design guidelines, they created a
+  consistent look and feel throughout their app.
+</p>
+
+<p>
+  After analyzing user comments, El Mundo discovered that readers considered
+  their app to be complicated and out-of-date. Therefore, they decided to
+  simplify the app’s functionality by removing features that were redundant.
+  They also removed sections of their app that were less relevant to their
+  readers, such as weather updates and movie trailers. Finally, they applied a
+  brand new internal development framework that they now use consistently
+  across all of their apps.
+</p>
+
+<h3>
+  Results
+</h3>
+
+<p>
+  Following the re-launch of their material design app, El Mundo saw a
+  <strong>45% increase in the weekly install rate</strong>. Readers now spend
+  more time in the app, with the average time spent in-app increasing from one
+  to three minutes.
+</p>
+
+<p>
+  Additionally, this redesign resulted in more readers providing positive
+  feedback around the new experience, increasing the app rating in the Google
+  Play store by 25.8%, from 3.1 to 3.9.

+  a mobile game publisher in São Paulo, Brazil. With a mission of <em>creating
+  fun for everyone</em>, Tapps has a portfolio of over 200 titles on the Google
+  Play Store, with roughly 70% of their installs coming from Android. Store
+  listing experiments have provided invaluable metrics to help their growing
+  team understand what makes the most effective product listings.
+</p>
+
+<h3>
+  What they did
+</h3>
+
+<p>
+  Tapps has increased their use of store listing experiments in the Developer
+  Console. They recently expanded their marketing team to allocate greater time
+  and designated resources to the Developer Console tools. <strong>"We can’t
+  stress enough how much value the store listing experiments have brought us
+  over the past months. Right now, our marketing team has a substantial time
+  allocated to these tests every week,"</strong> said Felipe Watanabe, head of
+  marketing at Tapps. With icons and screenshots, Tapps tested variations in
+  color, character positioning, and the overall amount of graphic detail. In
+  the description tests, they found that shorter messages with clear calls to
+  action and appropriate language localizations were most successful.
+</p>
+
+<h3>
+  Results
+</h3>
+
+<p>
+  By frequently conducting store listing experiments, Tapps gained valuable
+  insights that they have applied across their greater portfolio of games.
+  Results showed that shortening messaging, using contrasting colors,
+  reordering screenshots, and simplifying graphics often led to variant results
+  representing an average increase in performance between 5% and 50%. After
+  making changes based on the test results, Tapps saw <strong>install rates
+  increase beyond 20-30%</strong>.
