Your to-do list should be the answer to a question. When everything feels urgent and nothing moves forward, it's usually because your tasks have drifted away from why they exist. TOIDO is a to-do app that starts with the question. You frame the real issues as questions, hang tasks beneath them, and focus on the few questions that actually change things. WHY IT'S DIFFERENT β€’ Start with the question Write issues as questions ("How do we…?", "Is it true that…?") and give each one a working hypothesis. Tasks become the moves that test that hypothesis β€” not a pile of disconnected chores. β€’ Prioritize by impact, not urgency Rank issues by leverage β€” how much changes once the question is answered. Pick one or two questions to own this week and go deep. β€’ GO β€” today's moves first Launch straight into your open to-dos, paired with the questions they serve. Today's moves sit on top, ordered by impact. β€’ Answer the question When the work is done, turn your hypothesis into a conclusion and close the question for good. Answered questions stay, with their answers. β€’ Inbox β€” capture without sorting Dump any thought straight into the Inbox. Later, ask "what's the question?" and connect it to an issue β€” or let it go, guilt-free. β€’ Weekly review Clear floating tasks, revisit your questions, choose next week's focus. Anything you drop is logged and can come back anytime. β€’ iCloud sync Your issues and tasks stay in sync across iPhone and Mac on the same Apple ID. β€’ English & Japanese. Light & dark. Sidebar and keyboard shortcuts on Mac. You do the thinking. TOIDO just hands you the structure β€” and the question.
