Track sunlight, UV and vitamin D. Explore seasons and your daily light rhythm
Your day, in a different light. Solis brings sunlight, local UV forecasts and your vitamin D journal into one calm, considered space. Record time outdoors, log supplements and explore how daylight changes around you. A CLEARER VIEW OF TODAY See your local UV forecast alongside a sky that follows the day. Choose your city or use optional location access to put the conditions in context. A JOURNAL FOR SUN AND SUPPLEMENTS Record outdoor sessions and keep estimated vitamin D from sunlight separate from the supplements you log. Save supplement routines and confirm each dose after you take it. Look back through your calendar to see your recorded days in order. TOOLS FOR FOLLOWING THE LIGHT Use Sun Compass to explore the sun's direction and height. Turn the Season Wheel to see changing day length, sunrise and sunset throughout the year. Explore daylight alongside your planned sleep schedule with Circadian Rhythm, including everyday and travel views. HOME, YOUR WAY Pin the tools you use most and arrange your Home pages around your routine. Choose your preferred scenery and appearance. START WITHOUT AN ACCOUNT Use Solis as a guest. Your journal is stored on your device. Optional sign-in and personal-cloud backup let you choose how to keep a copy of your records. ESTIMATES, WITH CONTEXT Solis is a wellness journal, not a medical device. Vitamin D and light figures are estimates, not blood measurements. Solis does not diagnose or treat medical conditions, recommend a supplement dose, or establish a safe duration of sun exposure. Never extend sun exposure to meet a target. Use sun protection and seek advice from a qualified healthcare professional about health or supplement decisions.
