### 3/5 — quick review

*2023-07-30*

ok. elegant-looking UI style. free. basic is good.

but only runs from 100Hz to 10000Hz.

i downloaded this immediately to test my hearing above 10kHz, the numeric freq doesn't accompany the slider. it's pretty wonky. 

again love the basic, but these basics should BE there. 

BUT, i can see a GREAT utility here if it went from 20-20000Hz and ironed out the freq selection...
