Oh maan, there are soo many awesome tools and I bet more are coming. The main 3 ones for me are:

• Steemworld- shows all the information about the account, delegations, votes, comments, follow changes, payout overview per day/week/month...everything! You can find your profile overview here: https://steemworld.org/@greendeliverence
• Next one would be GinaBot. Discord bot who sends you notifications about people commenting on your posts, so you can reply immediately. The setup is pretty easy and you can find it here: https://steemit.com/ginabot/@ilyastarar/how-to-use-ginabot-and-get-steemit-seamless-notifications-for-free
• And last but deffo not least for me is Partiko. Great and stable iOS and Android app for interaction with Steemit. It doesn't crash at all, allows you to post and comment and also partial upvote. And you earn their tokens for every action and can change them for Steemit upvote from their account once in a while! Here the android version: https://play.google.com/store/apps/details?id=io.partiko.android&hl=en_US
