https://airdropalert.coma good site where you immediately see the status of the company, when it starts and when it is over, in addition, you immediately see the conditions on which you can get your air drop
I like Airdropalert. It is easy to track Airdrops. I also follow some groups and people that doing a good job related to airdrop tracking.
There were some other sites too, but not so good like Airdropalert.
