SimpEx - Simple Exercise
Your Fitness Readiness Coach
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Know your body. SimpEx turns your Apple Health data into the right training for today — now with guided challenges and an AI coach. More at simpexapp.com
SimpEx reads your body's daily readiness — HRV, resting heart rate, and sleep — and suggests the right workout for today. Not too hard, not too easy. Just right.
TRAINS WITH WHAT YOU HAVE
Tell SimpEx where you are and what equipment is around (or scan it with your camera). Home with nothing but a mat? You get a real bodyweight session. Full gym? Everything's on the table. Your workout never asks for gear you don't have.
EVERY STYLE, PROPERLY BUILT
Strength, HIIT, CrossFit, calisthenics, boxing, tennis, Pilates, yoga and more — each generated with warm-up, main work, and cool-down from a library of 3,000+ exercises with video demonstrations. Star your favorites and they're always one tap away.
AN AI COACH THAT ACTUALLY DOES THINGS
Ask the coach anything mid-workout — and let it act: "Swap the rows for dips." "Add barbell curls." "My lower back hurts, what instead?" It adjusts your workout on the spot, respecting your equipment and your body.
CHALLENGES WITH A SCOREBOARD
Take on benchmark workouts like Cindy in guided mode: press Start, watch the countdown, tap off every round. Your result lands on your personal scoreboard so next time you beat it.
PROGRESS YOU CAN SEE
Every workout is saved. Charts grow with every session, personal records track both weights and reps, and your activity calendar shows the streak building.
MARATHON MODE
Week-by-week run training with the right mix of easy runs, long runs, and strength days — plus warm-up and cool-down stretches runners actually need.
YOUR DATA, YOUR BODY
SimpEx reads HRV, sleep, and heart rate from Apple Health — read-only and optional — including data synced there by Apple Watch, Whoop, Ultrahuman Ring, and other wearables. No manual input needed. Available in English, German, Spanish, and French.
SIMPEX PRO
Unlimited AI workout generation, all training styles, marathon plans, AI injury adaptation, and the equipment scanner. Monthly or yearly subscription, payment charged to your Apple ID account.
