Integrately is an online tool to connect different software as a service (SAAS) apps together. Their target market is primarily business customers although automations can come in handy in many different ways. It could be as simple setting an automatic task in your to-do list software when you receive a certain email, to much more complicated tasks. Basically if you work in multiple applications, software such as this can save a lot of time and manual work by connecting different apps and data together.
Please bear in mind, this is a fairly new app but they are rapidly catching up to others. The closest similar competitor would be "Zapier" (also IFTT) which has many raving fans but can get very expensive. As a comparison, this free referral offer will give both the referrer and referee 500 (+ 200 for the base plan) tasks per month while the starter Zapier starter plan will give you 750 but cost $24.95USD per month.
Worth checking out if you need something like this now or might do in the future. They have not stated how long it will run for but the referral deal is for a limited time.
Mod: Use referral system below
ifttt seems cheaper to me.
