immune.fit

For athletes with an immune system that argues back

Find your active‑life sweet spot.

Push too hard and you flare. Rest too much and you lose ground. immune.fit tracks your energy, symptoms and training side by side, so you can do more of what you love without paying for it tomorrow.

Free to start. Works on any phone, no download needed.

A training plan that listens to your body

  1. 01

    Check in by text or voice

    Tell immune.fit how you slept, what hurts and what you did. Thirty seconds, in your own words.

  2. 02

    See energy next to effort

    Your energy, symptoms and training land on one timeline, so cause and effect stop being a guess.

  3. 03

    Train in your zone

    Set goals that fit the week you're actually having, and build from a baseline you can hold.

Symptoms

Log a flare in a sentence. See the week at a glance, and bring a one-page report to your next appointment.

Energy

A daily energy check, plus Garmin Body Battery and WHOOP recovery and strain in the same place.

Activity

Walking, lifting, yoga, sauna: set it, count it, and see how your energy responds week over week.

A companion that listens

Talk it through like you would with a friend who remembers everything and never gets tired of asking.

Walk in with the data

After a week of check-ins, immune.fit turns your logs into a one-page report for your rheumatologist, GI or PT.
