I am using IFTTT since it was in Beta and I am still using it. Very awesome app to automate social media stuff and now they have included Android and iOS automation too, which is awesome.
You can automate with just a few clicks. Make a recipe, share it or use shared recipes. It works like a charm!
This really the only service you will ever need. It focuses on business apps like quickbooks and so on, where as ifttt is more on IOT and social.
I'm a massive fan of Zapier, been using it since it launched and have intergrated so many services together using it, I honestly dont think my business could run with out it.
