The short version

  • Only Anki has a free tier, so it costs nothing to try first.
  • 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.; GoGuardian beacon generates alerts that a human must act on, often outside school hours, and districts that buy it without agreeing who responds at 11pm have created a liability rather than resolved one.
  • They diverge on capability: Anki covers Spaced repetition scheduling, GoGuardian covers Admin.
  • Prices and features above were last checked on 1 September 2026.

  • A teacher running an online assessment who needs pupil browsers locked to a single site for the duration without provisioning a separate lockdown browser.not Anki

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  • Shared decks, especially large medical school decks, can carry factual errors or become outdated, and there is no editorial review process verifying their accuracy.

GoGuardian

  • Beacon generates alerts that a human must act on, often outside school hours, and districts that buy it without agreeing who responds at 11pm have created a liability rather than resolved one.
  • Detection is language-pattern based, so it produces false positives on coursework about difficult subjects and misses coded or oblique expressions, meaning it should never be presented to parents as a safety net.
  • Filtering on school-issued devices follows pupils home, which surveils domestic internet use on a household's own connection, and districts have faced public objections when this was not disclosed clearly in advance.
  • No pricing is published, and the multi-year reseller bundles make it hard to compare against a filtering-only competitor without running a full procurement.
  • Coverage is strongest on Chrome OS and thinner on Windows, macOS and iOS, so mixed-device districts get uneven enforcement and end up running a second filtering product for the non-Chromebook estate.

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.

GoGuardian: Is GoGuardian required for CIPA compliance?

No. CIPA requires a filtering policy and technology, not a specific vendor. GoGuardian is one of several products that satisfy it.

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.

GoGuardian: Does Beacon monitor pupils at home?

On a school-issued managed device, yes, including outside school hours, unless the district explicitly limits the policy. This should be disclosed to families.

Anki: Do I need to pay for sync?

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

GoGuardian: Is Beacon included with Admin?

A starter level of Beacon is included with an Admin subscription. The 24/7 human triage service is a separate paid tier.

GoGuardian: Is Pear Deck part of the same licence?

No. Pear Deck Learning products are sold separately from the Admin, Teacher and Beacon suite even though the same company owns both.

GoGuardian: Can teachers view screens outside lesson time?

That depends on how the district configures sessions. Leaving screen viewing available at all hours is a configuration choice, not a product limitation, and it is the setting most worth reviewing.
