Recently the tumblr app is horrible. There are ads every two posts. Ads that take up your entire screen. Ads that put themselves at the top of your screen and take up half it. Ads that play sound automatically and can't be muted without touching the ad. Ads that automatically take you to the app store if you scroll by them. It slows my entire phone down to the point of locking up and needing to be restarted before it works again. This may as well be an ad viewing app. Social media for ads.
