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 โข Schedule, don't queue. Every task lives on a calendar-style timeline, blocked out by how long it takes. โข AI that plans your day. Tell Accomplish what to do and it suggests when, fitting tasks around your real calendar. โข Rules in plain language. "No meetings before 10am." "Deep work on Mondays." "Chores after 6pm." It schedules the way you actually work. โข One tap to commit. Accept a suggested time, or drag a task wherever you want it. BUILT TO STAY OUT OF YOUR WAY โข Fast, focused, and quiet - no clutter, no busywork, no endless settings. โข Durations and color make your whole day readable at a glance. โข A Live Activity keeps the task you're on, and the time left, on your Lock Screen and Dynamic Island. WORKS WITH YOUR CALENDAR โข Syncs with Apple Calendar and Google Calendar, so events and tasks share one timeline. โข Connects with Google Tasks to bring your existing lists along. GO FURTHER WITH ACCOMPLISH PRO โข Zoom out: see 3 days or a full week side by side. โข Repeating tasks: daily, weekly, or on your own cadence. โข 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/
