A daily symptom scan
Spot early signals you're run down by comparing resting heart rate, HRV, sleep, temperature and respiratory rate against your own baseline.
Data you need:
- Sleep and recovery: oura or garmin or whoop or polar or withings or ultrahuman or apple-health or health-connect
Run the daily scan
One prompt does it. freddy compares last night and the past three days with your 30-day baseline across the signals that often move first when you are coming down with something or carrying too much load, then tells you whether today is a day to take it easy.
Use freddy to compare last night and the past three days with my 30-day baseline. Flag changes in resting heart rate, HRV, sleep, temperature and respiratory rate, note any missing data, and tell me whether to take it easy today.
Works best after your ring or watch has synced last night's data.
What you'll see
You'll get something like: resting heart rate a little high for the third morning, HRV below your baseline, sleep a touch short, skin temperature and respiratory rate still near your norm. The short sleep and elevated resting heart rate are the main flags, so today reads as an easy day. Gaps are called out rather than filled in.
The example here is illustrative, not from a real day.
Good to know
Not every source records temperature or respiratory rate. If a signal is missing, the scan should say so rather than inventing a value.
HRV is not comparable across brands. Different devices use different HRV measures, so compare your HRV to your own history on the same source, never to another device.
Schedule or run this after your sources have synced. Last night's sleep does not exist anywhere until the ring or watch uploads it, so a very early run reports on the night before last.
This is not a clinician. It is good at noticing when your own signals drift from your baseline. Do not use it to diagnose illness.
