Flash Vocal — Addition

Why out loud?

“7 + 5 = ?” — “twelve”. No keyboard, no fingers to count on, no answer to pick from: out loud, you have to know it. Session after session the answer comes faster, until it is truly known by heart. The app measures the response time of every calculation: that is what tells whether the answer is truly known by heart.

How does it work?

1. 1

   Pick a table

   38 steps: every table from +1 to +10 in two parts (0 + n to 5 + n, then 6 + n to 10 + n), its review, and cumulative reviews from the +3 table onwards.

2. 2

   The equation appears

   A simple card: “7 + 5 = ?”. No distraction.

3. 3

   You say the answer

   Speech recognition validates in real time. The next card appears immediately.

4. 4

   Mastery stars

   Based on speed and accuracy: 1, 2 or 3 stars. The next table unlocks when you master the previous one.
