The following are apps that can help you with your habits. Some of them are free, other are freemium (free for some features, but paid for pro features), and other are fully paid. Paying $ for apps is always odd. The way I encourage you to think about it is, if its providing value to you, and actively helping achieve a habit, then investing in it is not a bad idea. You can also pay for a little bit, and then stop paying once you think you are not getting enough value.
Tool Finder - this is a webpage that helps you find an app for a particular need
Rize - This app “tracks” your activity on the PC. It can give you reports on how much time you are spending on email vs. word, vs certain websites. It’s good to assess how distracted or focus you can be during the day.
Freedom.to - This app is simple. Blocks distracting websites for a period of time on all electronic devices you would want.
Todoist - A to-do app with a lot of neat feature. My favorite is that it can sync with your calendar and has natural language processing. This means that you can write on your to-do app “Meeting with Econ group 3pm to 5pm on Wednesday” and it will create a to-do an a calendar event. It’s a great combo for quickly scheduling stuff in your calendar AND also having to-do’s in your calendar. There are other apps that do this btw. Here is a video of explaining how I use todoist.
Notion - this is a note-taking app, or you personal way to organize a bunch of stuff. There are a number of videos on YouTube about how to use it and set it up. Because it is so flexible, it can be overwhelming, so my recommendation is to look online for set-ups that other people have and copy theirs, then start adjusting to your needs. Here is a good place to start
Background Music for Work - Is just a bunch of links of playlist of cool music to work with.
