Train smarter.

SimpEx reads your body's daily readiness — HRV, resting heart rate, and sleep — and builds the right workout for today, with the equipment you actually have.
Built on Apple Health
HRV, sleep & heart rate, read-only
Works without a watch

AI workout builder
Your workout, built in seconds.
AI generates complete sessions — warm-up, main work, cool-down — and it only uses equipment you actually have.
Home with just a mat? Real bodyweight session. Full gym? Everything's on the table. Scan your equipment with the camera if you don't feel like typing.
Readiness
Know when to push. Know when to rest.
Every morning SimpEx scores your recovery from HRV, resting heart rate and sleep, and matches today's intensity to it.
Not a fixed template — your body sets the pace.

AI coach
An AI coach that doesn't just talk.
Ask mid-workout and it acts — “Swap the rows for dips.” “Add barbell curls.” “My lower back hurts, what instead?”
It edits your workout on the spot, respecting your equipment and your body.
Challenges & progress
Beat your own scoreboard.
Benchmark challenges like Cindy in guided mode — countdown, round counter, result saved to your personal scoreboard.
Every workout feeds your charts, records and streak calendar.

No. SimpEx reads from Apple Health, so iPhone alone works. If you wear an Apple Watch, Whoop, or Ultrahuman Ring, that data makes your readiness score sharper.
