Let me tell you another way in which the app is dangerously horrible. When you add a stocks widget to the home screen, the ticker value of the stock actually takes some time to update. Sometimes you gotta click it to see the updated value and then when you come back to the home screen, the widget has the same value. There were instances where I wondered how the price stayed the same for so many hours - turns out the value in the widget was not getting refreshed.
This was my only source of truth doing intraday trading (when i was not near a computer) until i figured out the bug
