SunGuard

The app dynamically adapts to your behavior: If you move into the shade or partial shade, your remaining sun exposure time is recalculated with a single tap. The same applies to activities like swimming, sweating, or spending time on reflective surfaces such as snow or sand. This ensures your estimate remains realistic and up-to-date at all times. You’ll be notified in time before your skin is damaged. The app also reminds you when to reapply sunscreen—for optimal protection all day long. Transparency is key: In the Info section, all calculations are clearly explained, and you’ll find in-depth information about UV radiation, skin types, and effective sun protection. The free version already offers all the essential features to reliably protect you from the sun. With the Pro version, you get even more out of the app: • Create multiple profiles and conveniently manage your whole family • Start tracking your sun exposure retroactively if you forgot to open the app in the morning • One-time purchase for €9.99 – ad-free for life Whether in everyday life, on vacation, or while exercising—this app adapts to you and helps you enjoy your time in the sun safely and mindfully. Not medical advice or a medical device!

Verdict
The clearest difference is update cadence: SunGuard at weekly against Horizn's every 4 months. SunGuard also leads on iOS requirement (15.1 vs 18). On price, ads, in-app purchases and device support there is nothing between them.
