About

Kizy

Most goal apps cheer you on while you get nothing done. Kizy doesn't. Kizy messages you first — every day — and it already knows what you committed to. Set one goal and a deadline. From then on, Kizy checks in with a message that references your actual goal, your actual history, and whatever you said last time. Miss a commitment? It notices. Say "almost done"? It treats that as the deflection it is. This isn't a chatbot you have to open and prompt. It's an accountability partner that stays on you until the deadline — counting down, escalating when you slip, and going quiet only when the goal is actually done. Kizy is for people who don't need another motivational quote. You know what to do. You keep not doing it. Kizy applies the pressure to close the gap. What Kizy does: - Messages you first, daily, at a time you choose - Remembers your goal, your reasons, and your excuses - Calls out deflection instead of applauding effort - Escalates when you break commitments - Tracks your deadline and asks, straight up, whether you hit it What Kizy won't do: plan your work for you, or bury you in questions. It watches, it remembers, it pushes. That's the point. Kizy is free to download with a 3-day free trial. After that it's an auto-renewable monthly subscription, charged to your Apple Account. It renews automatically unless canceled at least 24 hours before the period ends. Manage or cancel anytime in your Apple Account settings.
