Too many tasks, not enough clarity? Plinth cuts through the noise by sorting every item into the four Eisenhower quadrants — so you always know exactly what deserves your attention right now. — KEY FEATURES — • 2x2 Matrix View — see all four quadrants (Do, Schedule, Delegate, Delete) at a glance as a color-coded grid, with up to five tasks previewed per quadrant. • Quick-Add from Any Quadrant — tap the Add button inside any quadrant card to create a task already sorted to the right place. • Task Notes — attach optional notes to any task to capture context alongside the title. • Completion Tracking — check off tasks with a single tap; completed items are struck through and moved out of your focus. • Today View — surfaces your top five Do-quadrant tasks (urgent and important) so you can open the app and start working immediately. • Full Task List — browse every task across all quadrants in one flat list, filter by quadrant, and swipe to delete anything you no longer need. • Priority Ordering — tasks within each quadrant are sorted by the order you added them, keeping the most important items at the top. • Fully Offline — all data is stored locally on your device using UserDefaults. No account, no ads, no cloud sync required. Plinth is built for anyone who needs a fast, structured way to decide what to work on — whether you are managing a team, building a product, studying, or navigating daily life. Open the matrix, place your tasks, and get back to doing the work that matters. — Plinth Priority Matrix PREMIUM — Premium unlocks the full Plinth experience: unlimited tasks across all four quadrants, drag-and-drop reprioritization, the Today view, and a completely ad-free, fully private workspace — so nothing stands between you and your priorities.
