another thing i have tasker do is write down the hours i work every week by detecting the bluetooth tv in work and then the times my car stops in the morning and starts when i head home. then on friday if there are any hours that haven't been sent, tasker puts them into an email and i review it before sending.
i often think about switching to an iphone for the camera or some other reasons, but then i think about all the stuff ive made in tasker and how i probably won't be able to replicate it all on ios
Apple's Shortcuts app supports a number of automation scenarios — for example, I would implement the feature you mentioned with a rule which tells Toggl to start an entry when my location is within a certain radius of work and stop it when I leave. You can also create or add to a note, send emails, etc. Since I have the Pythonista app, that could even extend to running arbitrary code.
1. By default my phone remembers the last media volume level used with headphones. This does make some sense, but it is easy to accidentally get maximum volume blasted in your ear. I use Tasker to automatically reset the volume to a safe level when I plug in my headphones.
2. I find that the automatic screen brightness on my phone doesn't work well at all. In a dark room, it would not set the brightness to its minimum level. It also would not turn the brightness to maximum even in direct, bright sunlight. I prefer to just set the brightness manually, and avoid the poor guesses of the automatic brightness algorithm (which is claimed to be "smart" and aware of my preferences). The only problem with manual brightness control is that it's common to end up in bright sunlight with a very dim screen. It is impossible to use the phone under such conditions. So, I used Tasker to add a gesture. If I shake my phone relatively hard, twice, in an up and down motion, it sets the screen to maximum brightness. I use this all the time.
