FocusStack helps you stop drowning in tasks and start finishing what matters most. Built around a simple idea: you can't do everything, but you can do the right thing right now. FOCUS ON WHAT MATTERS The "Right Now" card surfaces your single most important task for the current hour - no decision fatigue, just clarity on what to work on next. SMART PRIORITY SYSTEM Tasks are ranked High, Medium, or Low. If you have no High priority tasks today, your Medium tasks automatically promote to the top - so you're always working on what matters most without touching a setting. PLAN YOUR WEEK & MONTH See your tasks across a 7-day week view or a full calendar month grid. Overdue days are flagged so nothing slips through the cracks. BACKLOG THAT WORKS Tasks without a date live in your backlog, sorted by priority. Schedule them to today, tomorrow, or next week with a single tap. BUILD MOMENTUM WITH STREAKS Every day you complete at least one task counts toward your streak. Watch it grow and stay motivated to show up every day. DAILY WRAP-UP At the end of your day, review what you finished, what you missed, and reschedule or move tasks to backlog in seconds. MORNING REMINDERS Get a gentle notification each morning with a count of your tasks for the day - so you always start with intention. FULLY OFFLINE Everything stays on your device. No account, no sync, no subscriptions. Your data is yours. FocusStack is for people who want to be deliberate about their time - freelancers, founders, students, and anyone who needs more than a basic to-do list.
