The interface is clean and it's ux/ui is nice, really simple to use.
It's the perfect solution for growing our business by helping us to convert more leads into customers.

What I like it most:
+ It has desktop and mobile app
+ Clean and simple to use interface
+ Unlimited websites
+ Customizable chat in 20 languages (including Spanish)

Downside is it doesn't connect to WhatsApp directly, but via Twilio or mfms (they're paid service, not free). Hope they can improve this part, since other apps like Boei, Rake or Re:plain (also Appsumo deals) do offer direct connection.
