Where each one falls short

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

Firefly III

  • There is no official managed hosting, so a non-technical user has no easy on-ramp the way Actual Budget offers with its paid hosted sync.
  • The double-entry-influenced model is less intuitive for newcomers than simple envelope budgeting, and the learning curve is real.
  • Automatic bank sync depends on the community-run importer and third-party connectors, and coverage and reliability vary a lot by bank and country.
  • Mobile access is via a web interface rather than a polished native app, which is a step behind Actual Budget or Lunch Money on phones.
  • Because there is no company behind it, security patching and feature development depend entirely on volunteer maintainer time.

IRS2Go

  • It only covers federal IRS matters, so it is no help for state tax filing or refund status, which is a separate system in every state.
  • Refund status information is not real time and can lag actual processing, which frequently confuses users expecting instant updates.
  • It is not a full tax filing tool, so users still need separate tax preparation software or a preparer to actually file a return.
  • Its usefulness is entirely seasonal, concentrated around the US tax filing period each year, with little reason to open it the rest of the time.
  • As with any official government app, it has been targeted by lookalike phishing apps and messages impersonating it, so users need to confirm they have the genuine IRS-published app.
