If you are using the Frosty theme, you should edit the file /components/com_easysocial/themes/frosty/toolbar/default.php and remove the codes below,

		<li class="<?php echo $view == 'apps' ? 'active' : '';?>">

			<a href="<?php echo FRoute::apps();?>">

				<?php echo JText::_( 'COM_EASYSOCIAL_TOOLBAR_APPS' );?>

			</a>

		</li>

As for removing the apps on the sidebar, you can do so by editing the file /components/com_easysocial/themes/frosty/profile/default.php and remove the codes below:

				<div class="es-widget-body">

					<ul class="widget-list fd-nav fd-nav-stacked" data-profile-apps>

						<li class="<?php echo !$activeApp ? 'active' : '';?>"

							data-layout="embed"

							data-id="<?php echo $user->id;?>"

							data-namespace="site/controllers/profile/getStream"

							data-embed-url="<?php echo FRoute::profile( array( 'id' => $user->getAlias() ) );?>"

							data-profile-apps-item

							>

							<a href="javascript:void(0);">

								<i class="icon-es-genius mr-5"></i> <?php echo JText::_( 'COM_EASYSOCIAL_PROFILE_TIMELINE' );?>

							</a>

						</li>

						<?php if( $apps ){ ?>

							<?php foreach( $apps as $app ){ ?>

								<?php $app->loadCss(); ?>

									<li class="app-item<?php echo $activeApp == $app->id ? ' active' : '';?>"

										data-app-id="<?php echo $app->id;?>"

										data-id="<?php echo $user->id;?>"

										data-layout="<?php echo $app->getViews( 'profile' )->type; ?>"

										data-namespace="site/controllers/profile/getAppContents"

										data-canvas-url="<?php echo FRoute::apps( array( 'id' => $app->getAlias() , 'layout' => 'canvas' , 'uid' => $user->getAlias(), 'type' => SOCIAL_TYPE_USER) );?>"

										data-embed-url="<?php echo FRoute::profile( array( 'id' => $user->getAlias() , 'appId' => $app->getAlias() ) );?>"

										data-title="<?php echo $app->getPageTitle(); ?>"

										data-profile-apps-item

									>

										<a href="javascript:void(0);">

											<img src="<?php echo $app->getIcon();?>" class="app-icon-small mr-5" /> <?php echo $app->get( 'title' ); ?>

										</a>

									</li>

							<?php } ?>

						<?php } ?>

					</ul>

				</div>

			</div>
