Tasker has a similar companion app, it just doesn’t work with as many things on my Pixel 8 Pro as Macrodroid. The only phone automation I rely on anymore is Wifi hotspot toggling based on connected Bluetooth devices, which Tasker is incapable of now even with the companion app. I really don’t know how Macrodroid does it.
Of the automation apps my preferred UI Automate with its flows. It allows the complexity of Tasker without becoming unreadable as the automations become big. It’s harder to edit and even worse without root than Tasker.
Without a distro to rally behind I’m personally somewhat skeptical. Ubuntu was the best shot we had but since switching everything over to SNAPs it’s on the slow side. With the number of Windows ads and early end of support for Windows 10 there’s a real opportunity for desktop Linux, but until there’s a well supported distro that genuinely doesn’t require using the terminal I can’t see there being mass adoption.
