I want to purchase event tickets that go on sale at a time not predisclosed. They're announced via Twitter and effectively sold out within 60-90 seconds. I only follow the handle that posts this announcement and receive no other notifications from Twitter.
Is it possible to make an arbitrary app (or even just Twitter) play a notification sound even when my phone is silenced? Alternatives, such as elevating all of its notifications to emergencies or similar solutions would suffice as well.
