SUNLIGHT: FRIEND OR FOE?
Sunlight can boost your mood, lower stress, improve sleep, and kick-start vitamin D production. It can also turn you into a walking tomato and increase your risk of skin cancer. Like most powerful forces in the universe, moderation is key.
MEET SOLA: YOUR PERSONAL POCKET SUN-NERD
Whether you're chasing a golden glow, hunting for vitamin D, or hiding from UV rays like a vampire, Sola helps you enjoy the sun without burning.
Unlike basic UV apps, Sola tracks your real UV dose over time — not just the current UV index. Smarter tanning, safer exposure, fewer regrets.
SCIENCE-BASED UV & VITAMIN D TRACKING
Sola calculates your sun exposure using real science, including:
• Current UV index forecasts
• Your skin type and existing tan
• Past sun exposure (yes, it remembers)
• Sunscreen SPF
• Whether you actually flip like a pancake instead of roasting one side…

solaWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
