You work on multiple projects (for multiple clients) on multiple browser tabs at the same time.
Time tracking app that lets you assign each browser window to a particular project. This way when you are multitasking (because you are waiting for something to complete on one browser while doing something in another), the app will automatically track all your work time on all projects simultaneously.
It drains your energy and the quality of your work also suffers.
A small app is running in the background and monitoring your activity. When it detects signs that might indicate you are multi-tasking, it will alert you and give you options to make it “shut up” momentarily, or help it learn what you are doing is not multi-tasking. The objective is for you to have a reminder not to multi-task.
Many time I’m listening to a video and my mind wanders as a result of what I hear. I would like to check something that came into my mind, then until the browser downloads the content and renders it, I would also like to jot a short note. I can’t do it today not only because multitasking on smartphones is not very good (or doesn’t exist), but the screen is too small to see it all.
Push the display to an external large screen device like a TV or monitor, a laptop etc. because of the large screen it could be split up and showing multiple apps’ output.
Many times you’re doing things in parallel. If you want to do your best you should really only concentrate on one thing at a time. There are, however, many tasks that can be done in parallel. Buying groceries and listening to an audiobook or a lecture. Doing 2 or 3 maintenance chores on your computer, switching between them when there’s a wait etc.
Have an online app that can track many tasks in parallel. You can start one task and a timer for it, then when you have to wait and switch to a new task you can start another timer for that as well. Both timers running in parallel until you stop them.
