 <p>
   Android Wear aims to provide users with just the right information at just the right time. Great
   Android Wear experiences are launched automatically, glanceable, and require zero or low user
   interaction. Designing apps for wearables is substantially different than designing for phones or
   tablets. There are different strengths and weaknesses, different use cases, and different
   ergonomics to take into consideration.
 </p>

 <p>
   The first step toward creating a great experience for users on Wear is to read the
   <a href="{@docRoot}design/wear/index.html">Android Wear design guidelines</a>, which provides
   instructions on how to build the best user experience for Wear apps. You should also review the
   <a href="{@docRoot}training/building-wearables.html">Building Apps for Wearables</a> training, to
   understand the basic implementation requirements for a Wear app.
 </p>

 <p class="caution">
   <strong>Important:</strong> To ensure a great user experience, apps for wearables must meet
   specific requirements for usability. Only apps that meet the following quality criteria will
   qualify as an Android Wear app on Google Play. Qualifying as a Wear app will make it easier for
   Android Wear users to discover your app on Google Play.
 </p>

 <p class="note">
  <strong>Note:</strong> For information about how to publish your Wear apps in Google Play, see <a
  href="{@docRoot}distribute/googleplay/wear.html">Distributing to Android Wear</a>.

   Frequently Asked Questions
   </h2>
 </div>

 <p style="margin-top:30px;">
   <strong>After I submit my app for Android Wear review, how will I find out if my app does not meet
   all the requirements for Wear?</strong>
 </p>
 <p>
   If your app does not meet the usability requirements described on this page, the Play Store team
   will contact you through the email address specified in the <a href=
   "https://play.google.com/apps/publish/">Google Play Developer Console</a> account associated with
   the app.
 </p>
 <p class="caution">
   <strong>Caution:</strong> Make sure your app meets the <a href="#fn">functionality
   requirements</a>, otherwise your app will not be considered a Wear app and will not be reviewed
   for Wear <a href="#ux">design and interaction</a>.
 </p>
 <p class="note">
  <strong>Note:</strong> For information about how to publish your Wear apps in Google Play, see <a
  href="{@docRoot}distribute/googleplay/wear.html">Distributing to Android Wear</a>.
 </p>


 <p style="margin-top:30px;">
   <strong>If my app does not meet the Wear requirements, will my new or updated app still appear on
   Google Play for phones and tablets and still be installable on wearables?</strong>
 </p>
 <p>
   Yes. The requirements described above only determine whether your app will be identified as an
   Android Wear app on Google Play and easier for Android Wear users to discover. If your app is not
   accepted as a Wear app, it will still be available to other device types, such as phones and
   tablets, and it will still be installable on wearables.

	<strong>After I submit my app for Android Wear review, how will I find out if my app does not meet
	all the requirements for Wear?</strong>
	</p>
	<p>
	If your app does not meet the usability requirements described on this page, the Play Store team
	will contact you through the email address specified in the <a href=
	"https://play.google.com/apps/publish/">Google Play Developer Console</a> account associated with
	the app.
	</p>
	<p class="caution">
	<strong>Caution:</strong> Make sure your app meets the <a href="#fn">functionality
	requirements</a>, otherwise your app will not be considered a Wear app and will not be reviewed
	for Wear <a href="#ux">design and interaction</a>.
	</p>
	<p class="note">
	<strong>Note:</strong> For information about how to publish your Wear apps in Google Play, see <a
	href="{@docRoot}distribute/googleplay/wear.html">Distributing to Android Wear</a>.
	</p>


	<p style="margin-top:30px;">
	<strong>If my app does not meet the Wear requirements, will my new or updated app still appear on
	Google Play for phones and tablets and still be installable on wearables?</strong>
	</p>
	<p>
	Yes. The requirements described above only determine whether your app will be identified as an
	Android Wear app on Google Play and easier for Android Wear users to discover. If your app is not
	accepted as a Wear app, it will still be available to other device types, such as phones and
	tablets, and it will still be installable on wearables.
