IFTTT Maker for Cortana was removed from the Windows Store due to copyright concerns, but we're happy to relay that the app is once again available on the store under a different name. Say "Hey" to Cortana Triggers. The app is pretty much identical to what was previously available for everyone to use, but without the IFTTT association in the branding.
Should you be unfamiliar with what exactly IFTTT Maker for Cortana (and now Cortana Triggers) actually does, it's essentially a neat tool to extend the functionality and capabilities of Cortana. With this app installed, you'll be able to control Hue lights, Nest, SmartThings, Dropbox, OneDrive, and more by connecting to and using IFTTT 'recipes' that can be created to automate tasks. It's all driven by the name of the free service, 'If This Then That'.
Better yet, Cortana Triggers is a Universal app, meaning you can download and install on both your PC and smartphone. Cortana Triggers is free to download, though is monetized by ads and there are some limitations such as the number of commands one can create and a window pop-up when Cortana executes IFTTT actions. This can be rectified by making a one-time in-app purchase of $4.99.
