First of all, thanks for your reply.
Can you explain the following:

"and on top of that, it offers a built-in bowser. And the only way users can access Hive.blog, Peakd.com or Waivio.com is through this built-in bowser in the Keychain app."
What is the downside to using this built in browser in the app?

"limited to using Hive apps via a dedicated browser, which they don't have."
Why don't they have it? You just said the browser is built into the app.
