Google Blogger is one of the best for those who want there own free website. They can write and share there own thinking to everyone by the blog. In case of using app in mobile, I will say don’t use app , it only consume your phone space , in case of using aap you can directly browse in google chrome and add the blogger website to your home screen or use other browsing app like opera etc. That is more effecient for you.
Thank you.
