Soluna puts any two calendars on every day. Gregorian and Hijri, Persian, Hebrew, Chinese, Coptic, Ethiopian, Indian, Thai or Japanese: pick two, and each day shows both. THE CALENDAR • Today, large, in both calendars, with the moon's phase • A month you swipe through, with the second calendar's day under every date • Holidays from each calendar as coloured ribbons: Eid, Nowruz, Rosh Hashanah, Chinese New Year and more • Your own events under each day, and new ones added in plain words: "Lunch with Sara tomorrow at 1pm" • A converter that reads any date in all ten calendars WORLD CLOCKS • Drag a ribbon of time to see any hour in every city • Good time for everyone: Soluna finds when you and every city are free at once, and marks it in green • Good hours per clock, so a card says when it is a good time to reach someone OCCASIONS • Birthdays, anniversaries and trips in any calendar, counted down • Reminders a day, a week or a month ahead • Move a holiday a day for the moon sighting, this time only PRAYER TIMES, IF YOU WANT THEM • Prayer times for where you are, or for a city you choose, with 23 calculation methods • The adhan at each prayer, with five voices to choose from • A Qibla compass that turns with you • Ramadan: the day of the fast, imsak and iftar, and a suhoor reminder • The next prayer, or iftar in Ramadan, counting down on the Lock Screen and in the Dynamic Island EVERYWHERE • Widgets for the Home Screen and the Lock Screen • iPad, with the month, your day and what comes next side by side • Apple Watch, with today's dates, the next prayer, the Qibla and complications for your watch face • English and Arabic, right to left, in your choice of digits The live Qibla compass needs a compass: on iPhone and Apple Watch it points the way, and on Apple Vision Pro Soluna shows the Qibla as an angle from north. One purchase covers Soluna on Mac, iPhone, iPad and Apple Watch. Your calendars, occasions and clocks stay on your device. For prayer times, only a rounded location is sent to the prayer times service.
