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.

Wally

  • The Internet Archive's capture of wally.me on 2 January 2019 stated the app is free ('Control your money seamlessly. And, it's free.'), and claimed rankings as the #1 finance app in 22 countries and top 10 in 52 countries at that time.
