About this app

📅 Pattern Calendar is a visual pattern tracker built around dates.
No long typing like a complex scheduler. Just tap a date and log recurring things — symptoms, habits, schedules, pet care, or chores. Add color dots or emoji tags, snap a photo, and see a whole month's flow at a glance.
Create your own topics: 💊 medication 🏃 exercise 📚 reading 🐾 pet care 🌱 watering plants ⚖️ weight
━━━━━━━━━━━━━━━━━━━━
📝 DATE-CENTERED LOGGING • Tap a date to add a quick entry or a detailed schedule • Attach one photo per entry — take one or pick from the gallery • Single-day or multi-day period entries • Local reminders for schedules that need them
🔴 DOTS & 😀 EMOJIS ON THE CALENDAR • Color dot tags and emoji tags • Single entries show as marks inside the date cell • Period entries show as color bars across the calendar • Read a busy month at a glance, no long text
🏷️ RECORD TYPES YOUR OWN WAY • Build your own topics: health, symptoms, exercise, pets, plants, and more • Count type — counts how often something happens • Number type — stores a value + unit (65 kg, 5 km, 1800 kcal, 7 h sleep) • Pick a color or emoji per type; edit name, unit, and style anytime
📊 PER-TYPE PATTERN ANALYSIS • This month's counts, totals, and most-logged type • Number types: latest, average, max, min, sum + trend graph • Plain-language insights: "18 times this month · 4 more than last month" • Streaks, average interval, first entry date, next expected date • Day-of-week chart and a ~6-month density heatmap • Time-of-day (morning/afternoon/evening/night) and day × time patterns • Compare two record types side by side
🏠 ANDROID HOME SCREEN WIDGET • Monthly widget: this month's dates, markers, schedules, and holidays • Today widget: today's date and what you logged • Number entries show as value + unit (e.g. 65 kg) • Tap to jump straight into the app
📥 IMPORT DEVICE CALENDAR • Pull in schedules from your phone's calendar — no re-typing • Choose a range and get an auto color tag per calendar • Read-only: never modifies your original events
🎌 HOLIDAY DISPLAY • Pick a country and region to sync holidays • Holidays show as named red dates, set up from first launch
💾 BACKUP EXPORT & IMPORT • Export calendars, types, and entries (values, memos, images) as one file • Save anywhere via the share sheet — Drive, Files, email • Restore with a tap; no server signup or cloud account
🌍 MANY LANGUAGES • Korean, English, Japanese, Spanish, Portuguese, German, French, and more • App text follows your device language automatically
🔒 LOCAL-FIRST & PRIVATE • Use without signup or login • Entries and images stay on your device • Reminders are local notifications • Backups are exported by you — no automatic upload
━━━━━━━━━━━━━━━━━━━━
WHO IT'S FOR • Track symptoms, pain, or condition changes by date • Build habits — exercise, reading, studying, medication • Log numbers — weight, distance, calories, sleep — and see trends • Follow a pet's meds, baths, or vaccination cycles • Capture changes best seen in photos • See patterns more visually than a plain calendar
📅 Log life by date with photos & tags — see patterns in charts & widgets
