Most to-do apps hand you a longer and longer list. Accomplish hands you a day you can actually do. Instead of stacking tasks in a queue, Accomplish places them on a real timeline, so you see when you'll do something, not just that you should. Add a task, give it a duration, and let AI schedule it into the open space around your meetings. Planning becomes doing. WHY ACCOMPLISH IS DIFFERENT โ€ข Schedule, don't queue. Every task lives on a calendar-style timeline, blocked out by how long it takes. โ€ข AI that plans your day. Tell Accomplish what to do and it suggests when, fitting tasks around your real calendar. โ€ข Rules in plain language. "No meetings before 10am." "Deep work on Mondays." "Chores after 6pm." It schedules the way you actually work. โ€ข One tap to commit. Accept a suggested time, or drag a task wherever you want it. BUILT TO STAY OUT OF YOUR WAY โ€ข Fast, focused, and quiet - no clutter, no busywork, no endless settings. โ€ข Durations and color make your whole day readable at a glance. โ€ข A Live Activity keeps the task you're on, and the time left, on your Lock Screen and Dynamic Island. WORKS WITH YOUR CALENDAR โ€ข Syncs with Apple Calendar and Google Calendar, so events and tasks share one timeline. โ€ข Connects with Google Tasks to bring your existing lists along. GO FURTHER WITH ACCOMPLISH PRO โ€ข Zoom out: see 3 days or a full week side by side. โ€ข Repeating tasks: daily, weekly, or on your own cadence. โ€ข Unlimited new tasks (the free plan includes 20 a day). Subscribe monthly or yearly, or buy Pro once and keep it forever. Schedule. Do. Accomplish. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
