Most Healthkit apps are single-mindedly practical, created with the sole aim of making you healthier or tracking your sleep. This app is the opposite. This app wants to creep you out big time. Deadline is an iOS app that uses a short quiz and the new Healthkit functionality in iOS 8 to create a timer that counts down towards your death.
If you need a stark reminder of your mortality as Day of the Dead approaches, the new Deadline app for iOS will do the trick. The $0.99 app combines the new HealthKit SDK from iOS 8 with a bit of personal information in order to estimate how much time you have left in life. This is basically the quantified self version of The Death Clock. Of course, Deadline can’t promise accuracy, but developer Alaric Cole, who also created the Fitly app for tracking your steps, told me he used algorithms similar to the ones insurance companies use to generate the estimate. If you make any changes to your lifestyle and measurements, you can recalculate the figure at anytime.
