Hola: Tanning Journal

A smart tanning tracker designed to guide your process—not just store photos. From the very first step, you select your Fitzpatrick skin type (I–VI), and the app calculates your recommended SPF along with a personalized safe sun exposure window in minutes. You define the areas you want to track—face, shoulders, back, legs, arms, chest—and capture a true baseline for each one: an honest starting point before any sun exposure.

Before heading out, start a Sun Session. A built-in timer tracks your time under the sun while logging SPF and location, with a clear progress bar showing your safe window in real time. As you approach your limit, the interface shifts from calm to caution—orange turns to red—signaling it’s time to step into the shade. Once you're done, you take a quick snapshot and rate your tan level from 0 to 10, automatically linking it to that session.

Each body zone evolves into a visual story of your progress. Baseline on the left, latest on the right, along with a day counter and a subtle sparkline graph that tracks your tan level over time. What your eyes might miss—a gradual shift in tone across days—the data makes visible. It’s not about guessing anymore; it’s about seeing real change.

With Compare mode, you can take any two snapshots of the same zone—baseline versus yesterday, or week one versus week two—and slide between them to reveal the difference. The transformation becomes undeniable. Context-aware reminders keep you consistent: no baseline? You’ll be prompted to create one. Spent time in the sun yesterday? You’ll be nudged to capture your progress. Everything works together to make your tanning journey intentional, safe, and trackable.
