Since I don’t use Android and never have in the past, I’m obviously not familiar with the app and only took a quick look at its Play Store page, but it looks like Apple’s Shortcuts app might be at least somewhat similar to that (but likely a bit more limited).
Sure, the OS is closed source and so is the review process, you kinda have to trust them to actually do what they promise. For everyday normal life stuff, it’s likely safe enough though. Obviously, if you’re a spy or a whistleblower operating in some high stakes scenarios, you’ll probably want something else, but you also probably don’t want Android unless it’s been seriously hardened (i.e. something like Graphene).
