Safari’s content blockers effectively block trackers and other Bad Stuff on the web, but that only works in Apple’s browser. Any other app you install on your iPhone or iPad can send all kinds of personal information to anyone, without you ever knowing. Your location, the details of your menstrual cycle, how long you spend asleep — pretty much anything.

Ulysses is therefore better than ever before. Come with me, and check out all the new stuff contained in Ulysses 17 for iOS.

Researchers built a smartphone app that can check blood pressure by simply recording a short video of someone’s face, then analyzing the blood flow under the skin.

High blood pressure can lead to heart attack or stroke so making an easy at-home test for it could save huge numbers of lives.
