Auscultation School — CSD Labs peaked at #8 on July 27, 2026, which remains its best rank over the last 30 days, though its 30-day average is a more modest #20. Today the app is only charting in smaller markets, led by Bosnia and Herzegovina at #37 and Brunei at #39/#40, with Zambia (#66), Honduras (#68/#72), Uruguay (#68), and El Salvador (#74) further behind. Movement is essentially flat to slightly negative — most positions show a 0 or -1 change versus the prior reading. Overall, the app has clearly faded from its mid-July peak and is now holding steady at low double-digit ranks in niche countries, with no signs of a rebound.
