💡 Things to Consider

When Choosing Capacities

  • →Learning curve required for object-based thinking and custom property setup

  • →Free tier has storage limitations and lacks AI features compared to competitors like Notion

When Choosing Due

  • →Ideal for quick, forgettable time-based alerts but should be paired with other apps for complex project management

  • →Only available on iOS/Mac platforms with no Android, Web, Windows, or Linux support

  • →Persistent nagging notifications may annoy some users rather than motivate them - test if this approach fits your workflow

⭐ User Reviews

Capacities

"Strong for networked knowledge management with object-based structure and calendar integration. Praised for daily notes workflow and AI features. Limited by pricing constraints on free tier, iOS app still in development, and some planned features like OCR not yet available."

Due

"Due is praised for its persistent nagging alerts, quick setup, and clean design, ideal for time-based tasks. Users love its reliability for critical reminders like medications or bills, with some using it daily for 8-10+ years. However, it has limited advanced repeat options and sync can be inconsistent (~80% reliability). Best for simple, forgettable time-based alerts rather than complex project management."

🎯 Conclusion

Both Capacities and Due are excellent productivity tools with their own strengths.

Capacities excels in Object-based notes with custom types, templates, properties, and bi-directional links, while Due shines with Persistent reminders that continue until acknowledged. The best choice depends on your specific needs, workflow preferences, and budget.

We recommend trying both tools to see which one fits better with your productivity style.
