Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Obsidian

  • Sync is a paid add-on at $4 per month billed annually rather than part of the app
  • Publishing to the web is a further $8 per month per site
  • Commercial use asks for a $50 per user per year licence, though the vendor states it is not required
  • Collaboration is limited compared with a hosted notes tool, since the vault is local files first

Structured

  • No monthly view available, only daily and weekly views, limiting ability to preview long-term schedules
  • Cannot export to Excel, PDF, or other printable formats; only JSON export available on Apple devices
  • Calendar import requires Pro subscription (except on web where free import is available)
  • Android and web versions significantly lag behind iOS version in features and performance
  • One-way calendar sync only; cannot export Structured tasks back to Google Calendar or other external calendar apps
