Recently, I tried Android app for Tumblr. At first it feels good but I found a serious feature lack in it. I was unable to search all the tags in this app. I was able to browse only featured tags. Also I can browse tagged tags of a post. But it may not have the tag I want to browse.
There is no way to browse the tags you want but there is a trick that works. You need to complete a simple workaround for it. This app let you browse tracked tags. Once a tag is tracked you can search it in the app.
How to track a tag on Tumblr?
>>Open Tumblr on your computer using favorite web browser.
>>After login search for the tag you want and click on “track”, it is opposite to the search term in search box.
Track feature on Tumblr is similar to saved searches on twitter. After tracking some of your favorite tags you can try to search them on Android app. I don’t know how many tags you can track but sure many tags.
