Asterfold is a sunset planner for the places you actually watch from. See where the Sun will set, aim your viewpoint, plan the evening, then record what the sky really did. LIGHT PATH STUDIO • A sky dome draws the Sun's real path for any place and date, coloured by golden hour, blue hour and twilight • Scrub through the day for the Sun's altitude, bearing and shadow length • The year's range of sunset and sunrise directions on the rim, plus shortcuts to the year's key dates • Calculated on your iPhone, so it works offline AIM YOUR VIEW • Save the exact spot you shoot from, then turn toward your shot on a first-person horizon, like turning your head • Pick your lens (14 mm to 200 mm, or your phone's camera) and the frame widens or narrows to match • Jump straight to today's sunset or the year's most northerly or southerly sunset, or point your phone at the view • See the dates this year when the Sun sets or rises inside your frame, and the next seven sunsets against it PLAN THE SESSION • Choose the light window: golden hour, sunset or blue hour • Add composition notes, gear, a reminder and a short checklist • Open the spot in Maps when it's time to go FIELD JOURNAL • After sunset, rate what you saw in two taps, then add colours, clouds, a note and, if you like, a photo kept privately on your device • Each check-in is compared with the forecast Asterfold saved before the sunset, never a later one • After three check-ins, your colour ratings adjust to your own sky, in small, capped steps • Filter your history by viewpoint, season, rating or cloud type; patterns show how many entries are behind them TONIGHT • Sunset, Stars and Sunrise ratings with plain-English reasons • Hour-by-hour low, mid and high cloud from MET Norway • For tonight, point forecasts 60 km and 180 km toward the setting Sun, where low cloud can cut off the light • Golden hour, blue hour, Moon and planets HONEST BY DESIGN • Calculated, forecast, estimated and observed data are labelled differently • Ratings are a rule-of-thumb estimate, not a probability or a guarantee • Sun positions assume a flat horizon; hills, buildings and trees are not modelled PRIVATE • No account and no analytics • Viewpoints, journal entries and photos stay on your iPhone • Only a position rounded to about 1 km is sent to MET Norway for the forecast ASTERFOLD PLUS Free includes the Studio, aiming and plans for 2 viewpoints, the journal, check-ins and tuning, tonight's ratings, the next 3 evenings and 45 days of events.
