Janssen TimeKeeper app for iPhone and iPad

Time Keeper is the first clock that bends time when you feed it with an open mind. Designed to empower people with blood cancer to reclaim time from cancer, Time Keeper encourages users to explore novel things. This puts your brain into learning mode and makes new memories, which makes time seem to last longer. Time Keeper has 14+ activities to try, anything from log drumming to origami to beatboxing.

Personalised based on your interests.
Simple to get started and use.
Easy to follow tutorials.

Time Keeper uses HealthKit to read your heart rate and oxygen saturation. This is used to determine a visualisation of how your perception of time changes as you complete activities. Data is not accessible by Janssen Pharmaceutica NV and is never stored.
