Your Stats tab isn't just a snapshot of last night — it's a window into how your body performs over time. Here's how to read it.
Your baseline range
The shaded blue area behind each metric is your personal normal range — built from a weighted 12-week average of your data. If you're newer to AlterMe, it uses all the data you've collected so far and expands as you build history. This range is yours specifically, not a population average.
The white bar shows last night's result (or today's, for activity). When it sits comfortably inside the shaded range, your body is performing as it typically does. When it falls outside, something shifted.
The trend arrows
Next to each metric you may see a green or red arrow. Green means the value is trending up, red means it's trending down. Importantly, you don't need to be outside your normal range to receive an arrow — the arrow reflects directional movement in your data, not just whether you've crossed a threshold. This is intentional. Small shifts over time are worth paying attention to before they become bigger ones.
What to look for
HRV trending down over several days — often a sign your body is under stress, not recovering well, or fighting something off
RHR trending up — can indicate accumulated fatigue, illness, or lifestyle factors like alcohol or poor sleep
Deep or REM sleep consistently below your range — worth examining lifestyle habits like stress, caffeine, or alcohol
Activity trending below your range — a signal to check in on your consistency
Stats vs. Today tab
The Stats tab and the Today tab serve different purposes. Stats shows your longer-term baseline and how last night compares to your 12-week history. The Today tab compares more recent data — last night's sleep or yesterday's activity against the last two weeks — to surface meaningful short-term shifts. Use both together for the fullest picture.
Changing your view
Switch between 1, 7, 30, and 365-day views using the dropdown in the top right to see how your metrics move over time. Longer views are best for spotting gradual trends. Shorter views help you connect specific nights or days to how you felt.
