For gardeners
Sun exposure for gardens.
Lumavyr explains sun exposure for gardens, balconies and windows by combining the Sun’s seasonal path with the horizon that blocks it. Photography remains the primary experience; garden planning uses the same precise visual language.
Separate potential Sun from visible Sun
A compass direction alone cannot tell you how long a balcony or garden bed receives direct light. Lumavyr calculates the potential solar window for a date, then applies a scanned obstruction profile where available. That distinction makes it clear whether a six-hour theoretical interval is reduced by a neighbouring building, roofline, wall or mountain.
Understand morning and afternoon exposure
Total hours can hide the pattern that matters to plants. A spot may receive a brief cool morning interval and a much longer afternoon interval, or the reverse. Lumavyr presents morning, afternoon and total potential direct Sun as labelled durations, with visible and blocked paths drawn differently so the result never depends on colour alone.
Compare the seasons before planting
Solar elevation and day length change throughout the year. A window that receives winter light can be shaded by an overhang in summer, while a garden corner can move from deep shade to long spring exposure. Date-based offline calculations help compare the same saved spot across seasons without a weather service or continuous network connection.
Keep location decisions private
Core calculations run in the native app rather than on a remote server. The website requests browser geolocation only when you explicitly choose Match my real sky, uses it transiently for the current solar position, and does not transmit it. No account is required for the core Lumavyr planning experience.
