❓ FAQ
Is this a real auditory test?No. It is a sequential visual digit stream with an optional beep. It is not a spoken Wechsler digit-span administration.
Why one digit at a time?Spoken span never shows the whole string at once. This lite copies that timing idea, not a licensed item bank.
Does a long span mean a high IQ?No. Span toys wobble with sleep, noise and strategy. This site never reports a deviation IQ.
