One number for how today may feel.
Feelcaster turns the day ahead into your Feelcast: a score from 0 to 100, set by the hardest waking hour coming and tuned to what you watch for.
- Good day80 to 100
- Bearable day50 to 79
- Bad day0 to 49
The same score runs hour by hour and across the 10-day forecast, so you can plan the week.

Get early access
It gets sharper every time you check in.
Once a day Feelcaster asks how you’re feeling: Good, Okay or Not great. Each answer keeps the weather from the hours before it, and Report shows what your bad days have in common.
- Log a symptom with when it started, how bad it was and what else was going on.
- Feelcaster learns the pressure swing you actually react to and adjusts your forecast.

Questions people ask
Is Feelcaster medical advice?
No. Feelcaster gives informational forecasts. It doesn’t diagnose or treat anything. Talk to your doctor about your symptoms and treatment.
How does Feelcaster know what affects me?
It starts from what research says tends to bother each condition, then adjusts to you. How strongly you say each one affects you, the triggers you pick and your own logs all shift it.
How early do alerts arrive?
A Feelcast Warning means a rough stretch is likely within the next 12 hours. A Feelcast Watch means one is possible within the next 2 days. Quiet hours, 10 PM to 7 AM, hold both back.
Do I need a smartwatch?
No. Feelcaster works from the weather alone. With Feelcaster Plus you can connect Apple Health or Fitbit, and readings from Apple Watch, Oura, WHOOP and Garmin come through Apple Health.
Does it work where I live?
Weather, air quality and pollen forecasts work worldwide. Radar and official National Weather Service alerts cover the United States.
What does it cost?
Weather, radar and alerts are free, with no ads. Feelcaster Plus is free for 14 days, then $5.99 a month or $39.99 a year. Plus Family covers up to 6 people for $59.99 a year.
