IMPORTANT
MySun provides model-based educational estimates—not medical advice, a diagnosis, a UV measurement, or a guarantee against skin damage. Sunscreen does not make UV exposure risk-free. Follow local guidance and consult a qualified clinician for health concerns.
Some features require an optional Sun+ subscription.

Really impressed with MySun. I’ve tried a few UV/sun tracking apps and this is the first one that feels genuinely useful day-to-day rather than gimmicky. The live UV index plus hourly forecast makes it easy to plan when to head outside, and the sun session tracker with reminders to reapply sunscreen is such a simple idea done really well. Love that it’s built around my actual skin type instead of generic advice. Also a big plus that everything stays private on-device — no ads, no tracking. Highly recommend if you spend time outdoors.
