ShiftForge
The science of your sleep, for ages 15–18. Pick a schedule and the two-process model shows your alertness hour by hour — when you'll be sharp, when you'll crash — plus your week's sleep debt. Then test a claim: does a later school start or a screen-free bedtime really help? Sleep as a science topic, not a tracker: nothing is recorded, and it's not medical advice.
▶ Play it nowBuilt for sittings of about 25 minutes on the screen. That is our design budget, not a measurement.
