what are the coolest apps you’ve used on TON?

There are so many, the ones I use every day are Catizen and Gamee. But really, even if it's expensive to use, what I definitely prefer is the native wallet on TG. 

With the Spaces to have a wallet for each app, the transactions, the animations, everything is so well designed that it makes you want to waste your money 😅 ( Oh, I know, I'm broke, I need to top up my Space for Catizen 😂)

Maybe ton keeper ?
Or you mean other airdrop apps ?
