Down Dog Yoga App offering 60% off annual subscription, bringing it down from $60 USD to $24 USD (c. $37 AUD)
I used the app a fair bit during the free period in April and really enjoyed it. Excellent customisation of length, type, complexity, goals for your Yoga sessions whether you're a beginner like me or more advanced.
It does also have HIIT, Barre and other workout style classes on. Haven't tried them myself but may be handy if gyms stay shut!
Payment is by Paypal or Credit Card, so FX fee may apply
