The short version

  • Each has a real cost: Anki the interface is functional rather than polished, and new users often find the initial setup, deck creation and add-on ecosystem confusing compared with a guided app like Memrise.; RawTherapee there is no catalogue, only a folder browser, so any library management, keywording or search has to happen in a separate application.
  • They diverge on capability: Anki covers Spaced repetition scheduling, RawTherapee covers Selectable demosaicing.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Anki

  • The interface is functional rather than polished, and new users often find the initial setup, deck creation and add-on ecosystem confusing compared with a guided app like Memrise.
  • iOS users pay a one-time fee of around $24.99 to $29.99 for AnkiMobile while every other platform is free, which is an unusual asymmetry that surprises new users comparing app store prices before they understand it funds development.
  • Anki has no content of its own; a new user gets an empty deck and either has to build cards manually or trust the quality of a community-shared deck of unknown accuracy.
  • The default scheduling algorithm requires understanding concepts like ease factor and interval to tune effectively, and default settings are not optimal for every subject or workload.
  • Shared decks, especially large medical school decks, can carry factual errors or become outdated, and there is no editorial review process verifying their accuracy.

RawTherapee

  • There is no catalogue, only a folder browser, so any library management, keywording or search has to happen in a separate application.
  • The default rendering is deliberately neutral and looks flat next to the camera JPEG, which means every user has to build their own processing profiles before the tool is pleasant to use.
  • Support for new camera models and for Fujifilm X-Trans sensors arrives later than in commercial converters because it depends on volunteer work and upstream library updates.
  • The interface presents several hundred controls across many tabs with little guidance about which ones interact, and the learning curve is measured in weeks rather than hours.
  • Batch export is slow compared with commercial converters and there is no GPU acceleration, so processing a large wedding shoot ties up the machine for a long time.

Answered from the vendors’ own pages

Anki: Why is the iOS app not free when everything else is?

AnkiMobile is a paid one-time purchase, commonly around $24.99 to $29.99, that the developer states directly funds ongoing development of the free desktop apps, AnkiWeb sync and infrastructure used by every platform.

RawTherapee: Does RawTherapee support Fujifilm X-Trans files?

Yes, but support arrived later than in commercial converters and results on fine detail still trail Capture One and Adobe on some bodies.

Anki: Is Anki really free on Android?

Yes. AnkiDroid, the Android app, is free and open source, built and maintained by a separate volunteer development team from the desktop project.

RawTherapee: Can it replace Lightroom entirely?

It replaces the develop side. It does not replace the catalogue, so you will need digiKam, darktable or something similar alongside it.

Anki: Do I need to pay for sync?

No. AnkiWeb, used to sync decks and review history across devices, is free.

RawTherapee: Are my edits stored in the raw file?

No. Edits are written to sidecar profile files next to the raw, so originals are untouched and profiles can be copied between images.
