About Vachag
A calm world for early mathematical ideas.
Vachag is a calm, playful early-math world made for children ages 4–5.
Children explore Number Grove through short, replayable journeys. Activities include counting, comparing quantities, composing and separating numbers, patterns, shapes, position words, measurement, sorting, and simple data play.
Every activity includes visible instructions, optional spoken guidance, and replay. The complete experience is available in English and Latin American Spanish. On iOS, Vachag supports VoiceOver, Dynamic Type, increased contrast, Reduce Motion, and other system accessibility settings.
Vachag is private by default. It has no ads, third-party tracking, child accounts, or gameplay analytics. Child profiles and progress stay on the device, and core play works offline.
The first three journeys are always available without a purchase. A parent or guardian can open the protected grown-ups area to choose a monthly or annual Vachag Plus subscription, restore purchases, manage sound, or erase local profile data. Both subscription options unlock every Vachag Plus journey while active. Apple handles billing on iOS, and Google Play handles billing on Android. Manage or cancel subscriptions through the store used for the purchase; subscriptions do not automatically transfer between stores.
Vachag is an educational play experience and does not promise a particular learning outcome.
