AnchorShift is the first intelligent scheduler designed to sync your sleep, energy, and life with your work rosterβusing the science of circadian rhythms. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://anchorshift.ca/privacy.html Whether you are a nurse, first responder, or industrial worker, switching between days and nights often leads to "Shift Drag"βthat brain fog and exhaustion that ruins your days off. AnchorShift fixes this by calculating exactly when to sleep, use caffeine, and block light to flip your internal clock faster. KEY FEATURES: The Night Shift Algorithm Stop calculating sleep math in your head. Simply input your shifts, and AnchorShift generates a minute-by-minute biological plan. We tell you the optimal "Anchor Sleep" windows, when to blast bright light for alertness, and the exact moment to put on sunglasses to protect your recovery. Energy Analytics You canβt improve what you donβt measure. Log your daily energy levels (1-5) and visualize your performance trends over time. Our analytics engine detects patterns in your fatigueβalerting you to "Post-Shift Crashes" before they happen so you can adjust your routine.

Import your personal Google Calendar directly into the app. See your work roster alongside family events, doctor appointments, and social plans to identify conflicts instantly.
