Easy way to keep track of deadlines! Instead of a cluttered list, this shows you only one task. Insanely useful for high priority deadlines. I usually keep the app open while focusing on work as it shows me a ticking timer. It also keeps track of tasks done.
Just scroll through your agenda to see the great things you've done in the past or plan far into the future. Oh, and if you didn't check something off today, Supreme will automatically bump it forward for you. Super simple.
