  • Good day80 to 100
  • Bearable day50 to 79

Set it up once. It watches all day.

  1. 1.

    Tell it what to watch for.

    Choose from more than 100 conditions and symptoms, from migraine to asthma, or type your own. Feelcaster suggests the triggers that matter for each, and you set how strongly each affects you.

  2. 2.

    It reads the sky and your body.

    Pressure, heat, cold, humidity, air quality, pollen, sun and storms where you are. Connect Apple Health or Fitbit and a short night counts too.

  3. 3.

    It alerts you early, with one thing to do.

    A Feelcast Watch when a rough stretch is possible in the next 2 days. A Feelcast Warning when one is likely within 12 hours. Each comes with a plain next step.

How Feelcaster works

Look out for the people you love.

Add a child at home or a parent in another city. Feelcaster forecasts for what they live with, where they are, and alerts you when a rough stretch is coming for them.

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.
