Sleep smarter, not longer. ShiftRest is built only for shift workers - nurses, paramedics, pilots, truckers, and anyone whose body fights their schedule. Most sleep apps assume a 9-to-5 life. ShiftRest doesn't. It uses your real shift roster and your personal chronotype to calculate the exact hours your body will rest best - even when you're working 7pm to 7am. HOW IT WORKS 1. Take a 60-second chronotype quiz 2. Connect your Calendar (or enter shifts manually) 3. ShiftRest tells you when to sleep, when to wake, and how rested you'll be BUILT FOR SHIFT WORK - Circadian Rhythm Engine - personalized sleep windows by chronotype, age, gender - Smart Shift Detection - auto-imports rosters from your calendar - Sleep Debt Tracker - see what you owe your body, track recovery - Shift Readiness Score - know if you're rested enough before clocking in - Sleep Sounds - white, pink, brown noise; rain, ocean, forest, fan - Wind-Down Reminders - smart notifications timed to your shift - Home Screen Widgets - next shift + sleep recommendation at a glance - Apple Health sync - sleep data flows seamlessly SHIFTREST PRO Calendar sync, full sound library, advanced widgets, and personalized insights. Weekly, monthly, and yearly plans. Cancel anytime. PRIVACY Your sleep data stays on your device. We don't sell, share, or upload it. Designed with input from sleep researchers.

Creatine is not a painkiller. It does not work on the day you take it ā it works by saturation. Your muscle stores fill up over weeks and drain again when you stop. Brim turns that into one number you can actually watch. YOUR SATURATION, NOT A STREAK The number rises on the days you dose and falls on the days you miss, by roughly one to two percent a day. It is not a counter that resets to zero to punish you. It is an estimate of where your muscle creatine actually stands, from a model fitted to the published research ā which means a missed day costs you exactly what it costs you, no more. A PLAN BUILT FROM YOUR BODY ⢠A daily dose calculated from your body weight, not a flat scoop line ⢠Standard or loading, with the real trade-off between them spelled out ⢠A projected curve to the day you reach full ⢠Reminders timed to when you actually take it SEE WHAT A BREAK COSTS Progress draws your saturation over time, tells you what a fortnight off would do, and counts the days back to full. Miss a day and you will see it move. That is the entire point. EVIDENCE, GRADED The library answers what people actually ask. Is loading necessary. Does creatine damage your kidneys. Does it cause hair loss. Is it different for women. Is it worth it after fifty. Every article carries a grade ā Established, Emerging, Early or Myth ā so you can tell a settled question from an open one instead of guessing. QUIET BY DESIGN ⢠A Home Screen widget with today's number ⢠Apple Health reads your weight so the dose stays right as you change; nothing is written back ⢠No account, no sign-up, no email ⢠Your log lives on your iPhone Brim Pro unlocks the full history, the forecast, protocol switching and the complete library. Logging your dose is free, always ā a tracker that locks the tracking is not a tracker. Brim Pro is an auto-renewing subscription, offered yearly (with a free trial) or weekly.
