Calendari is an iOS productivity app that combines a personal calendar with an AI assistant, shared groups, and smart notifications. It helps users manage their schedule by text or voice, share events with others, and get reminders based on travel time and context. Core features: Smart calendar * Month view with events for the selected day; switch between personal calendar and any group calendar. * Tap a date to open a day sheet with events grouped by time (All Day, Morning, Afternoon, Evening). * Create and edit events with title, date, start/end time, location, and notes. * Mark events as completed; events are stored locally with SwiftData. AI assistant * Chat with an AI planning assistant (Claude) via text or voice. * Create events by natural language (e.g. “Add dentist tomorrow at 2pm”, “Bible study at 7pm for the Bible Study group”). Events go to the personal calendar by default; you can say a group name to add to that group. * Schedule questions: “What’s on my calendar today?”, “Am I free tomorrow at 4pm?”, “Do I have plans in the morning?” * Planning: “Would next week be good for vacation?”, conflict checks and alternative times. * Recurring schedules: “I work Monday–Friday 7am–6pm” creates recurring events; the AI can bulk-edit or bulk-delete when you say your schedule changed. * Reschedule: “Move my 10am appointment to 9am” or “Reschedule dentist to Friday.” * Travel: Get driving time between two places; the AI can suggest route order and when to leave when you have multiple stops. * Smart reminders: For events with a location, the app can schedule “time to leave” alerts using travel time; for events without a location, the AI can set reminder minutes (e.g. 15, 30, 60) based on event type. * Supports English and Spanish (responses follow app language). Groups and collaboration * Personal calendar vs group calendars: each group has its own calendar; the bottom bar shows a “Personal” option plus group avatars to switch views. * Create or join groups via a sheet: create a group (name + invite code) or join with an invite code; invite code can be copied with “Copied” feedback. * Group details: view group name, invite code, share link, members, shared events; optional group image and pin color (for the map); leave group or delete (owner only). * Event creation policy per group: who can create events—Everyone, Admins only, or Owner only. * Shared events: events added to a group are synced via CloudKit so all members see them on the group calendar and map; only the creator can edit a group event (unless policy allows). Map and location * Map view shows event locations with pins; pins can be colored by group. * User location and traffic; tap a pin for directions (MapKit). * Events can have a location string; coordinates are resolved for travel time and map display. Notifications * Location-based: for events with a location, “time to leave” alerts are scheduled using current location and driving time (with buffer). * AI-timed: for events without a location, the AI can set “reminder X minutes before” (e.g. 15–120) based on event type. * Notifications are requested and scheduled via UserNotifications; background location is used for departure alerts. Account and sync * Account sheet: sign in with Apple ID (iCloud); profile picture and display name; view iCloud status and list of groups; delete account option. * CloudKit: groups, shared events, and membership are synced through CloudKit; personal events stay local. Personalization * Themes: five color themes (e.g. Warm Brown, Deep Purple, Emerald Teal, Crimson Rose, Ocean Blue) with matching gradients and accent colors for the UI. * Language: English or Spanish; onboarding and AI responses follow the selected language. * First-launch onboarding introduces: AI assistant, smart calendar, groups, map/notifications, and personalization.
