Lumeday is a calm home for your whole day. Instead of a workout app, a water app and a habit app that never talk to each other, you compose one timeline — and get one honest number for how body and mind are actually doing. ONE TIMELINE FOR THE WHOLE DAY Add workouts, hydration, mindfulness and your own custom blocks to a single day spine, reorder them, tick them off, and set a reminder before each one. Build tomorrow in seconds from a one-tap routine, or save your own. LUME BALANCE — ONE HONEST NUMBER A 0-100 daily score computed on your device from six things you actually did: activity completion, movement, hydration, mindfulness, sleep and seven-day consistency. Any dimension with no data that day is left out and the rest are reweighted, so the score is never padded and never punishes a gap. Tap it to see exactly what moved it. A STREAK THAT FORGIVES Qualifying days build a streak that survives one miss a week, with milestones grounded in real habit research rather than the 21-day myth. PROGRESS YOU CAN READ Hydration, movement, mindfulness, sleep and mood each get a trend and a plain change against your own last seven days. Set specific goals and watch a ring fill, with a projection of when you will reach the target at your current pace. A CONTENT LIBRARY THAT SCHEDULES ITSELF Guided breathing, mobility flows, focus and wind-down sessions, filterable by length, type and mood — and any of them drops straight onto your timeline. LUMEDAY PRO (optional subscription) - Cross-domain patterns: whether your mindfulness or hydration days really precede better-scoring days, each rated by strength and shown only when there is enough data to mean anything - Bio-Sync: a plain-language plan tweak grounded in your own numbers - Your full history, the weekly review ritual, a shareable summary, premium sessions and unlimited routines - 9.99 US dollars per month or 59.99 US dollars per year, with a 7-day free trial - Payment is charged to your Apple ID at confirmation. The subscription auto-renews unless canceled at least 24 hours before the end of the period; manage or cancel in your Apple ID Settings The whole timeline, your streak, reminders and today's balance stay free, forever. Lumeday offers general wellness guidance to help you organize healthy habits. It is not medical advice, diagnosis or treatment. Targets are general references and vary with your body, activity and health — talk to a clinician about your own needs.
