My ideal GTD app would offer:
- great native interface on Mac and iOS
- reliable fast sync
- next/later/someday split
- shared lists or even better, ability to delegate tasks
- location reminders like Checkmark (i.e. multiple physical locations for a location category, such as “Groceries”)
Nice to have:
- Reminders auto-import
- Ability for 3rd party apps to interact (mainly email clients)
Reasons why I don’t like particular apps:
- Todoist: due-date-based interface; you can do GTD but it’s clearly not the priority, Mac app is clunky
- Things: no sharing, no location reminders, limited app integration
- Wunderlist: no location reminders, no someday category
- Checkmark: location reminders can’t be in a project/list, no Mac app, no app integration
- OmniFocus: no sharing, complicated interface, Mac App especially takes way too much screen space per task, limited app integration
- 2Do: clunky interface, sync unreliable
- Asana: clunky interface (still my preference for teams but not good enough for personal GTD), no Mac app
