Your ADHD brain doesn't need more pressure. It needs a nudge at the right moment. Luma helps you start, keep going and finish, with Mochi, a little companion who has your back and never judges. FOCUS TOGETHER (BODY DOUBLING) Work alongside other people, live and anonymously. Seeing others get stuff done makes it easier to begin. Send and receive encouragement. POMODORO & FOCUS TIMER Short focus sessions, breaks that actually rest you. Ambient sound (brown noise, pink noise, Mochi's purr) and the screen stays on. ROUTINES Morning, evening, chores, work: break your day into small, easy steps. REMINDERS Gentle reminders to drink, move, breathe, or do what you planned. BREATHING A few minutes to reset when everything feels like too much. Built for ADHD and neurodivergent minds, diagnosed or not. Luma is not a substitute for medical care Term of Use (EULA) : https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy : https://www.privacypolicies.com/live/c29c8d15-d0fb-4e5e-8eb4-53793a63a2a4
