## What is Flash Vocal?

Subtraction tables are practised out loud.

A subtraction 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 back on their fingers. A child who answers
out loud, at a steady pace, has no time to count back: they know. Flash Vocal
— Subtraction 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 (answers 0 to
  5, then 6 to 10) so the child is never overloaded
- Never a negative answer: every subtraction from 1 − 1 to 20 − 10, with
  an answer between 0 and 10
- A review of each table, then cumulative reviews mixing every table
  learned so far: −1 to −3, −1 to −4… up to −1 to −10
- One-minute sessions: 1, 2 or 3 stars depending on the number of
  correct answers
- A guided demo before the very first session: "5 − 2 = ?"

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 — the first tables: taking away 1, 2 or 3 without counting back
- Ages 7 to 8 — every table up to −10, crossing ten, at speed
- Remediation — filling a missing reflex, whatever the age
- Teachers — up to 30 pupils tracked separately

The natural companion to Flash Vocal — Addition: the same tables, in the same
order, read backwards.

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 — 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.
