  • Each has a real cost: Akiflow no native data export feature - tasks cannot be exported to CSV, JSON, or other standard formats; HEY there is no free tier and no monthly billing option, so trying it beyond the trial means committing to a full year upfront.
  • They diverge on capability: Akiflow covers Universal inbox, HEY covers The Screener.

Where each one falls short

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

Akiflow

  • No native data export feature - tasks cannot be exported to CSV, JSON, or other standard formats
  • Mobile app integrations limited to 7 native apps compared to 30+ on desktop and web versions
  • Designed for individual users only with no team collaboration features or shared workspaces
  • No native project management capabilities to group related tasks or track project-level progress
  • Limited task-to-event conversion functionality restricting workflow flexibility

HEY

  • There is no free tier and no monthly billing option, so trying it beyond the trial means committing to a full year upfront.
  • Adopting HEY means changing your actual email address, not just installing a new client, which is a bigger migration than switching apps on an existing address.
  • The Screener and categorisation model is a real departure from a standard inbox, and some users take time to adjust or find it gets in the way for high volume mail.
  • Short vanity addresses carry steep additional annual fees, up to 999 US dollars a year for a two character address.
  • It does not connect to or manage existing Gmail, Outlook or iCloud accounts, so it cannot be used as a general client the way Mimestream or Apple Mail can.
