Start using the app today! --SARTRE INCLUDES-- DASHBOARD Your go-to operations center for managing each day. Instead of a looming and overwhelming list of tasks, this page is split into the following sections to maximize productivity: 1) Today’s Main Goal – the most important thing you want to achieve that day 2) Three important tasks – additional vital things you want to get done 3) Something that gives me joy – an activity that will de-stress and relax you, preventing you from getting overwhelmed 4) Tasks and activities – everything else you want to get done You can categorize your tasks and activities, and simply tick them off once complete! FUN SECTION This page is purpose-built to help you relax and have fun. You can add your favorite fun activities from a pre-built list, or create your own, and then add these to your daily activities section with ease. The page also contains a Quote of the day, and a riddle to get your brain moving. It even includes recommendations for Books, Movies, and TV Shows which updates regularly! PROJECTS SECTION Here, you’ll be able to manage all the long-term projects you want to get done – from reorganizing your room, to learning to code, to getting great exam grades! Simply split each project into achievable steps, and tick them off as you go along – moving projects into the Completed section. ASSIGNMENTS SECTION Whether for work or school, stay on top of your assignments with this page. Give each assignment a description, a due date, and a category, and see it through to completion. REFLECTION SECTION At the end of each day, it’s vital to take a moment to reflect. With Sartre, you can rate each day from 1-10 in terms of Happiness, Productivity, Personal Development & Learning, Family & Relationships, and Overall. You can then fill in the best and worst things about that day, and what you’re grateful for, before writing a journal entry as short or long as you would like.
