How it works

The knowledge layer stays free.

Reference, citations, safety content and your own records cost nothing. Pro adds optional tools, which differ by app — monthly, annual, or lifetime.

Knowledge stays free

Every app includes a free tier with full access to the reference library — the plain-language guides, cited sources, and educational content that make professional knowledge readable. No account required, no time limit.

That isn't marketing language. It is a constraint we build against. "For everyone" would be hollow behind a paywall. The knowledge layer — what the professional actually knows — stays free.

Free

$0

The knowledge layer — reference, citations, safety, and your own records.

  • Complete reference library
  • Plain-language guides and cited sources
  • Your own records, whatever the app lets you keep
  • Raw export
  • No account required, no time limit

If a subscription lapses, the free raw export still works.

Pro

$4.99–$7.99
per month, or annual / lifetime

Optional tools that differ by app — never access to knowing.

  • Everything in Free, plus:
  • Monthly, annual (best value), or lifetime
  • The Pro tools listed on that app's page
  • OmniMathematics: one feature, the formatted study report of your marks

Restore Purchases in the app. Cancel a subscription in Settings. Apple processes the payment.

Per-app prices (US)

Same structure on every app. Most household and learning apps: $4.99 / month · $29.99 / year · $79.99 lifetime. OmniAvia and OmniCadence: $5.99 / $39.99 / $99.99. OmniLex (a professional tool): $7.99 / $49.99 / $129.99.

OmniMathematics: $4.99 / month, $29.99 / year and $79.99 lifetime. Monthly and annual include a 7-day free trial for eligible new subscribers, and Family Sharing is on for all three.

Annual is about half of twelve months. Lifetime is a one-time unlock of the same Pro tools — not a second paid product. You only pay for Pro in the apps you use. There is no bundle.

Why this model?

We chose this structure because it respects three commitments:

  1. The knowledge layer is free. If you just want to understand how legal codes work, or read plain-language medicine labeling, or learn physics — that costs nothing.
  2. Your records stay yours. Each app keeps its raw export free, so it still works if Pro lapses.
  3. The tools can be subscribed or owned outright. Lifetime Pro is the one-time. The knowledge layer is not for sale.

Availability

All eleven apps have been submitted to App Review. An app's page shows its App Store link once the app is available there.
