## The case on TickTick

Build a web-first personal subset rather than trying to clone every native app client, but expect significant engineering overhead on calendar sync and offline state.

Hardest parts:

- Cross-platform synchronization and offline-first state reconciliation
- Multi-directional external calendar integration (Google Calendar sync)
- Robust natural language date/time grammar parsing across locales
- Snappy chart rendering and smooth Kanban drag-and-drop interactions

## The case on Todoist

You can build a web-based Todoist clone for personal use with AI tools, but you will miss the native cross-device sync engine and 19 years of polish.

Hardest parts:

- Multi-platform offline-first sync engine with conflict resolution
- Robust natural language parsing engine for complex date/recurrence expressions
- Real-time collaborative project sharing with presence and role permissions
- Fluid drag-and-drop calendar and board reordering performance
