Addition tables are practised out loud. A sum appears, the child says the answer, the app listens and validates. Table after table, the answer becomes a reflex. A child who taps a digit can count on their fingers. A child who answers out loud, at a steady pace, has no time to count: they know. Flash Vocal โ€” Addition only validates an answer that is genuinely spoken, something no multiple-choice exercise can check. A path of 38 steps - All 10 tables, from +1 to +10, each split in two halves (0 to 5, then 6 to 10) so the child is never overloaded - A review of each table, then from +3 a cumulative review of the tables learned (+1 to +3, +1 to +4โ€ฆ up to +1 to +10): 38 steps - One-minute sessions: 1, 2 or 3 stars depending on the number of correct sums - A guided demo before the very first session: "2 + 1 = ?" What you follow - Result screen: a pace indicator (animals, bikes or racing cars, the child's choice) and how the child felt about the session - Statistics per table and per session, with the reaction and pronunciation time of every answer - Optional daily reminder, which only fires on days without a session Who it is for - Ages 6 โ€” the first tables, building numbers up to 10 - Ages 7 to 8 โ€” every table up to +10, at speed - Remediation โ€” filling a missing reflex, whatever the age - Teachers โ€” up to 30 pupils tracked separately Free and subscription Tables +1, +2, +3 and the first half of +4 are available without a subscription, with no time limit and no cap on sessions, for one profile. The subscription opens the whole path and several profiles. Family (3 profiles) and Education (30 profiles) plans, for 1 month, 3 months, 6 months or 1 year. Auto-renewable, cancel anytime in your App Store account settings. Privacy Speech recognition runs entirely on the device. No speech is ever transmitted, no recording is kept. The app works 100% offline, with no ads, no account and no tracking. Only anonymous crash reports are sent in case of a failure, to fix bugs โ€” never any personal or voice data. Available in English, French, German, Spanish, Italian, Portuguese, Dutch, Polish, Czech, Turkish, Catalan, Ukrainian and Russian: the app speaks the device's language. French is built in; the other voices download once, then everything works offline.
