Kaper is a companion app that helps people with executive functional challenges do the next one thing to fulfill a task as small as getting out of bed to a task as big as launching a product. Built for ADHD and every kind of executive function struggle — heavy days, burnout, the mornings when nothing moves. Kaper doesn't hand you a list, a streak, or a schedule. It hands you one step — small enough to do right now, in your body, where you are. When that step is done, the next one appears. Set a destination, and Kaper walks you there: one move at a time, eight steps at a sitting. No tracking. No guilt. No noise. Just the next one thing, every time you open it. — One step on screen at a time, never a list — Steps small enough to start from a frozen state — Works for a single hard morning or a years-long goal — Quiet by design: music only, no voice, no notifications begging you back Your first month is free. Then $19.99/month. Start where you are. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
