Personal Calendar is a calm, beautifully themed daily companion. It unifies your calendar, assistant, notes, habits, to-dos, weather, and market rates into a single glanceable home screen β€” then gets out of your way. THREE VISUAL DIRECTIONS β€’ Morning Light β€” clean, minimal, indigo. A crisp everyday look. β€’ Almanac β€” warm editorial paper with cream, ink, and amber. β€’ Midnight β€” dark glass with electric lilac. Beautiful at night. Switch themes any time from Settings. Every surface, icon, and category color is routed through the active theme β€” no bleed, no compromise. CALENDAR THAT ACTUALLY WORKS β€’ Six views β€” Day, Week, Month, Agenda, Kanban, Timeline β€” all from one cursor. β€’ Overlapping events render side-by-side as parallel columns, like Apple Calendar. β€’ Week auto-scrolls to today. Month cells show category-colored dots; tap a day to jump to Day view. β€’ Customizable week start β€” Monday or Sunday. NATURAL-LANGUAGE QUICK ADD Type β€œDentist tomorrow at 3pm for 1h” β€” we parse the title, category, date, and duration. No forms to fill. ASSISTANT CHAT Ask for events, todos, and notes in plain English. The assistant adds them straight to your calendar, with a subtle thinking indicator while it works. CUSTOMIZABLE HOME β€’ Weather hero with conditions, highs/lows, humidity, and a live feels-like. β€’ Today / habits / todos counters. β€’ USD, EUR, and gram gold in Turkish Lira β€” refreshed automatically. β€’ Up next, habit chips, open to-dos, and a gorgeous moon phase / sunrise / sunset card. Use the pencil button in the header to toggle sections on or off. WEATHER YOU CAN TRUST Live Open-Meteo data in Β°C or Β°F, hourly for the next 24 hours and daily for 10 days. Real sun, moon, cloud, rain, snow, thunder, fog, and cloud-moon glyphs β€” no more sun icons on rainy days. PRIVATE CLOUD SYNC Your data is backed up to your private cloud in the background. Works fully offline too β€” nothing is ever required to be online. HABIT STREAKS, NOTES, WEATHER LOCATIONS Build small daily habits with streak counters. Keep lightweight notes with pin and search. Watch the weather in every city you care about. NO ADS, NO TRACKING, NO ACCOUNT REQUIRED.
