Your todo list keeps growing, but you still don't know what to do first? DAYBOX separates remembering from prioritizing. First write down everything for today. Then choose the three that matter most and promote them to the top. Finally, give time only to the tasks that need it. ā–  Your day with DAYBOX 1. DUMP — Write everything down No priority, no category. Just a title. As fast as they come to mind. 2. PROMOTE — Pick the important three One tap lifts a task into FOCUS. Up to three you truly want to finish today. 3. PLAN — Timebox only what matters Not everything goes on a schedule. Only the tasks that need focus. 4. DO — Run your day, then it becomes a record. ā–  Why DAYBOX is different Ā· One field to add — capture your day in 30 seconds, no setup. Ā· Today's three — because not everything is equally important. Ā· Timeboxing is optional — you're never forced to schedule everything. Ā· No auto carry-over — you decide what yesterday's unfinished tasks become. No todo debt. Ā· One day, one sheet — no projects, no folders. Just today. Ā· Lock Screen & Home Screen widgets — see your progress and what's next without opening the app. Ā· Streak — counts the days you picked three, not the days you finished them. Ā· Repeats, suggested — routines show up as candidates. Nothing gets added for you. Ā· Tomorrow's three — decide tonight, start right away in the morning. All data stays on your device. No ads, no account, no sign-in. Write all, focus on three.
