This app includes much information about hypertension, such as its cause, result, treatments, etc. There are some animations in the app to help you understand some concepts like how atherosclerosis develops.
Expensive in app purchase
Though the animations are great, there are only very few animations available unless you pay in app. However, it costs more than 200 HKD and I think it is too expensive for such a short topic of hypertension.
Tips for using the product
Checkout youtube for more animations about medicine.
