I haven't used esteemapp yet and I have no phone until next week hahaha. But seems like an amazing app (and contest) so I'll try to find a way to participate.
No matter what, I didn't know about that app so I'll explore it deeply. Seems promising.
Thanks again for your comments, always bring good vibes and results hahaha
it's not necessary to have used the app, you could draw something inspired by eSteem (like @dunsky does) and write about it. there is minimum 350 words :) all the best!
