The Reliable Teammate for Shift Workers. Shift work shouldn’t cost you your health. AnchorShift is the first intelligent scheduler designed to sync your sleep, energy, and life with your work rosterβ€”using 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"β€”that 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 can’t improve what you don’t measure. Log your daily energy levels (1-5) and visualize your performance trends over time. Our analytics engine detects patterns in your fatigueβ€”alerting you to "Post-Shift Crashes" before they happen so you can adjust your routine. Smart Calendar Sync Your life doesn't stop just because you work nights. 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. Precision Notifications Get nudged at the exact right moments. β€’ "Caffeine Window Closing" (Protect your sleep) β€’ "Light Blast" (Boost alertness mid-shift) β€’ "Wind Down" (Prepare for recovery) WHY ANCHORSHIFT? Standard calendars just tell you where to be. AnchorShift tells you how to be your best self when you get there. We don't just track your sleep; we optimize it. SUBSCRIPTION PRICING AnchorShift offers a Pro subscription to unlock the full Nightshift Algorithm, advanced Analytics, unlimited tasks feature, and custom notification settings.
