Provetree Household
A one-time purchase for the whole household. The current price is shown here and at checkout.
Provetree Household is a one-time purchase for every learner in the household (up to 5). It includes all algebra-track packs (Algebra Foundations, Algebra 1, Algebra 2, Trigonometry, and future algebra packs), unlimited Solo Discovery, full household mastery tracking, and the household leaderboard. No subscription, no ads, nothing in the game asks a kid to spend money.
Infrastructure is covered by roughly five sales a month. If the service ever sunsets, entitled households receive the content as an offline export.
If a one-time purchase is not in the budget, Khan Academy remains a trusted free option for algebra practice.
Named because it is the highest-trust free alternative, not a partner.
