Analyse de l'application A Solar Compass pour le 13 octobre

A Solar Compass calculates the exact moment the sun aligns with any bearing on Earth — from your current position toward any target location on the globe. Set your source location (via GPS or manual coordinates) and a target location. The app computes the precise local time when the sun's azimuth matches that bearing, displays a live countdown, and — if you want them — sends reminders so you never miss the window. KEY FEATURES • Sun alignment calculator — uses real astronomical equations (Julian Day, solar declination, local sidereal time, azimuth) to find the next alignment within a 5-day look-ahead window. • Live countdown — a real-time timer counts down to the exact alignment moment, right on the home screen or Lock Screen. • Home Screen & Lock Screen widgets — keep the countdown visible without opening the app. • Share to Solar Compass — share a map pin or a link to a place from Maps, Safari, or Messages, and apply it as your position or your target in one tap. • GPS location — tap "Use GPS" to populate your coordinates automatically. • Manual coordinates — enter any latitude/longitude for full control. • Automatic timezone detection — fetches the correct UTC offset for your source location so the displayed time is always local. • Alignment reminders — turn on notifications 60, 30, 10, 5, and 1 minute(s) before the alignment, plus one when it happens, so you have time to step outside. One tap on the bell icon turns them on or off. • Report wrong calculation — send feedback directly from the result screen if something looks off. • Privacy-first — location data is stored on your device. Anonymous crash reporting is opt-in. HOW IT WORKS 1. Open the app — your last-used or IP-detected location loads automatically. 2. Confirm or adjust your source and target coordinates. 3. The next alignment time and a live countdown appear instantly. 4. Turn on reminders (the bell icon) to be notified before the moment arrives. PERMISSIONS USED • Location (when in use) — to detect your position via GPS for the calculation. Never sent to any server without your consent. • Notifications — to deliver alignment reminders (opt-in, and can be turned off in-app at any time). No account required. No sign-up. No ads.
