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 weβ¦?", "Is it true thatβ¦?") 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.

Verdict
The clearest difference is update cadence: Lucid at every 3 days against TOIDO's monthly. TOIDO's advantage is device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
