A trio of dedicated task-automation apps for the iPhone released on the App Store back in February by the IFTTT (If This Than That) service are available on the Apple Watch as of today.
The refreshed Do Button, Do Note and Do Camera apps now feature compatibility with the Apple wearable, empowering users with the ability to assign complex actions to the virtual button on the Watch's tiny screen, including actions that tie into third-party services that have not yet rolled out first-party support for the Apple Watch.
In addition to Apple Watch support, these apps have also gained native iPad interface in today's update while adding the following new channels: Scout Alarm, ecobee, iSmart Alarm, Zubie, Mojio, Moni.ai, Nimbus Note, Harvest, WallyHome, HomeSeer, ThermoStat and Wireless Tag.
