The title covers it, really - all SWAM individual instruments and bundles are 33% off until the end of August. No coupons needed, they’re already marked down in the iOS App store - $20 or £20 GBP, or maybe 20 Euros for most individual instruments, with a small discount for buying or completing a bundle.
It’s quite hard to be sure you’ve seen them all because the App store never shows them all on one page. Look through both the individual ones and the bundles and follow each one to find the other. Eventually you should see them all.
Despite being signed up for their newsletters, I’ve never actually been notified of the iOS sales - I just look periodically.
They’re features restricted compared to the desktop ones and some have a greyed out knob on the main screen, but it’s not in a way that really matters much. Personally, I think they’re much better value and support for older versions of iOS is really quite good, so far - most run on iOS 12. My 2017 iPad Pro has iOS 16 and runs all of the ones I’ve bought well.
