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.; UltraCamp per-reservation pricing scales linearly with growth, so a large camp pays substantially more than it would under a flat licence and has little leverage until it passes 2,000 reservations and enters quoted territory.
  • They diverge on capability: Anki covers Spaced repetition scheduling, UltraCamp covers Per-reservation registration.
  • 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  • Shared decks, especially large medical school decks, can carry factual errors or become outdated, and there is no editorial review process verifying their accuracy.

UltraCamp

  • Per-reservation pricing scales linearly with growth, so a large camp pays substantially more than it would under a flat licence and has little leverage until it passes 2,000 reservations and enters quoted territory.
  • UltraCamp retains 30% of photo gallery sales, a revenue share far above the 3% it takes on merchandise, which turns a parent-facing nicety into a meaningful cost of doing business.
  • Health and medical record handling is thinner than CampMinder's, so camps with a staffed health centre and daily medication rounds often find it insufficient.
  • The interface and reporting are functional rather than modern, and building the unlimited custom reports on offer takes administrator time the camp has to fund itself.
  • The $1,200 annual minimum means very small camps pay for reservations they never make, so the effective per-reservation cost for a camp of two hundred is closer to $6.

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.

UltraCamp: What will it actually cost us?

Take your reservation count times $4.00, or $3.75 above a thousand, subject to a $1,200 annual minimum, plus $299 setup and any data import. Then add card processing at roughly 2.5% plus $0.35 on tuition.

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.

UltraCamp: Is there a contract?

No. UltraCamp sells without a term contract, which is unusual in this market and materially reduces switching risk.

Anki: Do I need to pay for sync?

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

UltraCamp: What does the photo gallery cost?

UltraCamp keeps 30% of photo sales. If parents spend heavily on photos, price that before enabling the module.

UltraCamp: How does it compare to CampMinder on health records?

CampMinder is stronger. If you run a health centre with a nurse and medication logs, test that area carefully before choosing UltraCamp.
