Built by 47 Industries
Production cross-platform mobile app. Real-time shared calendar system with AI schedule scanning, custom work templates, and multi-user synchronization.
Context
Traditional calendar apps are designed for individuals, not relationships. Couples and families struggle to coordinate schedules across separate apps, leading to missed events, double-bookings, and communication breakdowns. Workers with variable schedules waste time manually entering the same shifts week after week.
Production System Deployed
CalPal reimagines the calendar as a shared experience. Real-time sync keeps everyone on the same page. Shared events display as "Us" so you know at a glance what's happening together. Work Templates let users define their schedule once and apply it to any week in seconds. AI Schedule Scanner reads paper schedules and creates events automatically.
Operational Scale
A complete calendar ecosystem built for real relationships. Shared calendars with permission controls, Quick Schedule for fast weekly planning, custom fields for tracking what matters, break tracking with net hours calculation, recurring events, categories, and both light and dark modes.

Context
Multi-user scheduling coordination across heterogeneous calendar platforms represents persistent operational friction. Standard calendar applications lack shared event visualization, automated schedule generation from templates, and rapid data capture from physical schedule documents.
Variable shift workers execute repetitive manual data entry operations weekly. Healthcare professionals, shift-based workers, and service industry personnel invest significant time transcribing paper-based schedules into digital calendar systems. No existing calendar platform addressed these specific operational requirements.
Production System Deployed
Cross-platform mobile calendar application engineered for multi-user scheduling workflows. System implements real-time data synchronization across users, AI-powered optical character recognition for schedule extraction, reusable template architecture for recurring events, and extensible custom field schema. Production infrastructure serving couples, families, and shift-based workforce segments.
Shared Calendars
Invite your partner, family, or coworkers to share calendars. Everyone sees the same events in real-time with customizable permission controls.
Shared Events ("Us")
Mark events as shared and they'll display as "Us" on the calendar. Perfect for date nights, family activities, or team meetings.
Quick Schedule
Create a week's worth of work events in seconds. Select days, fill in details, and generate all events at once with reusable templates.
Work Templates
Define your work hours once with custom fields like Provider, Assignment, or any variable you need. Reuse them every week.
Custom Fields
Track what matters to you with dropdown menus, text fields, or duration pickers. Fields are stored separately and editable on each event.
AI Schedule Scanner
Snap a photo of a paper schedule and let AI automatically create all your events. Works with work schedules, class schedules, and more.
Break Tracking
Log lunch breaks and see your net working hours automatically calculated. Know exactly how much time you actually worked.
Recurring Events
Set up daily, weekly, monthly, or yearly recurring events. Complex patterns supported with easy-to-use interface.
Architecture & Infrastructure
Cross-Platform Mobile
React Native with TypeScript for iOS and Android deployment from a single codebase. Native modules for platform-specific features, optimized performance, and smooth animations.
Real-Time Backend
Node.js/Express API with PostgreSQL database. Real-time synchronization via WebSockets ensures shared calendar updates propagate instantly across all connected users and devices.
AI-Powered OCR
OpenAI Vision API integration extracts structured event data from photos of paper schedules. Parses dates, times, locations, and custom fields, then creates calendar events automatically.
Flexible Schema Design
JSONB storage for custom event fields enables user-defined data structures. Work templates with dynamic variables support any scheduling workflow without schema migrations.
Operational Scale
Production deployment through iOS App Store and Google Play Store distribution channels. System executes real-time multi-user calendar synchronization with immediate cross-device propagation. AI schedule scanning pipeline processes photographic input of paper schedules and generates structured calendar events automatically.
Freemium revenue model with native in-app subscription infrastructure. Custom event field architecture and reusable template system enable flexible scheduling workflows for healthcare professionals, shift-based workers, and service industry personnel managing variable schedule patterns.
