Apps that are also capable to auto-execute operations when specific events occur.
What I'm not able to find is a solution that doesn't need a running "daemon" to work.
For example in tasker, I can execute a task by clicking on its shortcut only if tasker is enabled as a running app (correct me if I'm wrong), which is not needed since I'm not using triggered tasks.
Is anyone aware of something capable to execute e certain task-list (e.g. in car: start gps, start bt, set media volume to high, start navigation software) by user interaction and thus without the need to have an always running app?

Among a dozen tried, many have the option to use task-lists via shortcut, but found only Trigger is able to work without its own service running.
