Shift - Jet Lag Sleep

Shift helps you plan light, sleep, and caffeine timing around trips across time zones. PLAN YOUR TRIP Choose your departure and arrival airports and enter your flight times. Shift creates a schedule before, during, and after your flight, with a predicted adjustment timeline. Edit your trip, plan a return, and save a completion summary when your trip ends. FOLLOW YOUR PLAN • See local time alongside an estimated body clock. • Review cues for today and the next two days. • Follow action windows that stay visible while they are in progress. • Mark cues complete, skip a cue, or set a reminder. • Add Home Screen and Lock Screen widgets for your next action. Complete cues directly from a Home Screen widget. • View your next cue on a paired Apple Watch. BETWEEN TRIPS Shift+ includes an everyday light, sleep, and caffeine schedule, cue-completion summaries, an adaptation profile, and PDF export. APPLE HEALTH With your permission, Shift reads wrist temperature, sleep, heart-rate variability, and resting heart rate from Apple Health. Available readings can inform estimates and appear in the app. Sleep totals cover the last 24 hours with overlapping records counted once. HRV and resting heart rate include sample dates. If data is unavailable, Shift uses population-based estimates or shows no reading. Body-clock alignment and adaptation timelines are forecasts, not direct measurements of recovery. PRIVACY No account is required. Health and trip data are stored on your iPhone. Schedule and completion data are shared on-device with Shift widgets; health readings are not included in widgets. Cue snapshots can be shared with your paired Apple Watch. Shift reads from Apple Health and does not write health data back. ACCESS • Free access includes a trip-plan preview. • Trip Pass unlocks the full trip protocol and cue logging for 14 days on this iPhone, with individual cue reminders. It is a one-time consumable purchase; completed purchases cannot be restored after reinstalling or on another device. • Shift+ offers monthly or yearly subscriptions with unlimited trips, Everyday mode, reports, PDF export, and opt-in automatic cue reminders. Shift keeps up to 48 upcoming reminders scheduled and refreshes them when you use the app. Family Sharing is supported where available. • Any eligible free trial, the price, and the billing period are shown with the plan. Subscriptions renew automatically unless canceled in your App Store subscription settings. Shift is a wellness planning tool. It does not diagnose or treat medical conditions.
