Creatine is not a painkiller. It does not work on the day you take it — 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 — 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 — Established, Emerging, Early or Myth — 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 — a tracker that locks the tracking is not a tracker.
