Heliophilia: Daylight Tracker is an elegant iOS application crafted by product designer Yannis Abelas that combines solar tracking with mindful daily reflection. Designed for individuals who align their routines with the natural rhythm of the sun, the app calculates and visualizes day length, sunrise and sunset times, and live UV Index metrics for any selected location. Through interactive annual daylight graphs and soft sky gradients, users can observe how daylight shifts day over day and season across the year. Beyond solar observation, Heliophilia integrates a thoughtful gratitude journal designed to anchor the end of your day. Users are prompted each evening to reflect and record one thing they are thankful for, transforming daylight tracking into a peaceful daily ritual. The application also supports iOS Home Screen widgets, custom daylight cards for social sharing, and smooth multi-location swiping. Built with an uncompromising stance on digital wellness and privacy, Heliophilia functions completely offline without requiring accounts, sign-ups, or third-party trackers. Offered as a clean, one-time purchase with no subscriptions or in-app ads, it delivers a calm, self-contained experience tailored for slow mornings, golden hour enthusiasts, and mindful living.
