Biorhythm

Biorythm brings four everyday rhythms together in one calm, carefully crafted place: your biorhythms, the Moon, the Sun and space weather. Enter your first name and date of birth once. That's it: no account is needed for the free app, and your details stay on your device (and in your own device backups, if you use them) and are never sent to us. BIORHYTHMS See your physical, emotional, intellectual and intuitive cycles on an interactive chart covering the past week, today and the week ahead. Drag across the chart to explore any day, read what each cycle traditionally stands for, and spot critical days, when a cycle crosses the zero line (including double and triple critical days). MOON Today's phase and illumination, rendered live. Moonrise and moonset for your location, the next new and full moon, supermoon and micromoon notes, and upcoming solar and lunar eclipses through 2040. SUN First light, sunrise, golden hour, solar noon and sunset, with a countdown to the next moment of light. An estimated UV level, calculated on your device from the height of the sun (a clear-sky estimate for general context). SPACE WEATHER The current Kp index of geomagnetic activity, solar wind speed, the strongest solar flare of the past 24 hours and a 24-hour trend, based on public data from NOAA's Space Weather Prediction Center. Plain-language notes explain what the numbers mean and when auroras may be seen further from the poles. READINESS A daily readiness score from 0 to 100 on Home, combining your biorhythms, the Moon, space weather and daylight, with a short briefing and a clear "why this score" breakdown. WIDGETS Two large home-screen widgets (your cycle curves, or the next three days with the Moon and space weather) and, on iPhone, lock-screen widgets for your next critical day. Free, drawn from a snapshot that stays on your device. OPTIONAL EXTRAS Add what you want, each on its own: • Mood logger: two quick check-ins a day, a calendar and a chart of your mood next to your cycles. Entries stay on your device. • Notifications: a calm morning brief, a heads-up before a critical day and a space weather alert, all on your device. • Extra waves: six more rhythms, from Aesthetic to Mastery. Plus (monthly) unlocks every extra. PRIVATE BY DESIGN • No account needed for the free app; your personal details never go to our server. • Your name, date of birth and location are stored on your device (and in your own device backups, if you use them) and are never sent to us. • Location is optional: use your device's location or search for a city offline. Sun and Moon times are calculated on your phone. • Usage statistics and crash reports, linked only to a random app ID, are sent only if you allow them. You can switch them off at any time in Settings. • "Delete my data" in Settings removes your details from the device and resets the app ID. • Mood entries stay on your device. Purchases go through Apple and RevenueCat; an account is needed only to buy an extra or claim a free week. Plus is an auto-renewing monthly subscription. Payment is charged to your Apple ID at confirmation and renews unless cancelled at least 24 hours before the period ends. Manage it in your App Store account settings.
