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.; Gaggle pricing is quoted per student per year with no published rate, and because it is charged on total enrolment rather than on accounts actually monitored, small districts pay a markedly higher effective rate than large ones.
  • They diverge on capability: Anki covers Spaced repetition scheduling, Gaggle covers Content scanning.
  • 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  • Shared decks, especially large medical school decks, can carry factual errors or become outdated, and there is no editorial review process verifying their accuracy.

Gaggle

  • Pricing is quoted per student per year with no published rate, and because it is charged on total enrolment rather than on accounts actually monitored, small districts pay a markedly higher effective rate than large ones.
  • False positives are structural, not a tuning problem: fiction assignments, song lyrics, health coursework and jokes between friends all trigger review, and each escalation consumes counsellor time the district funds itself.
  • The service reads children's private writing on school accounts, and civil liberties groups have documented cases where flagged content led to outing LGBTQ students or to discipline rather than support, which is a governance risk a board must accept explicitly.
  • Coverage is limited to district-issued accounts, so a student using a personal phone, a personal email address or an encrypted messaging app is invisible, which is where much of the behaviour the district worries about actually happens.
  • Escalation depends on the district maintaining accurate contact lists and staff who answer calls; when a named contact leaves and the list is stale, the service escalates into a void and the district only discovers it after an incident.

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.

Gaggle: How much does Gaggle cost?

It is quoted per student per year based on enrolment and requirements. No rate card is published, and effective rates fall substantially with district size.

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.

Gaggle: Is the tipline an extra charge?

No longer. From 1 July, districts on the full Safety Management solution get SpeakUp for Safety and the web filter safety integration at no additional cost; each previously carried a per-student charge.

Anki: Do I need to pay for sync?

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

Gaggle: Do humans read every alert?

Trained reviewers assess flagged items before escalation. That human layer is the core of the service, not an optional tier.

Gaggle: Does it monitor personal accounts or phones?

No. It covers district-issued Google or Microsoft accounts. Personal devices, personal accounts and encrypted apps are outside its reach.

Gaggle: What are the privacy obligations?

Districts sign a data processing agreement covering FERPA and applicable state student privacy law. Negotiate retention and scope in that document rather than relying on the marketing page.
