Built overnight
Last night's sleep sets how much you start the day with, measured against your own usual rather than a generic target.
Reps 2.0on the App Store
Reps builds your energy from how you slept, draws it down with what you do, and shows what your coffee is covering up. REX, your coach, explains any of it in plain words.
For iPhone, iPad and Apple Watch.


Energy
Reps follows your energy through the whole day and keeps caffeine on its own band, so you can see when a coffee is carrying you and when it will wear off. Tap why, and you get the answer in words, not another dial.
Last night's sleep sets how much you start the day with, measured against your own usual rather than a generic target.
Moving around draws it down, and a workout shows its own cost on the curve, so an afternoon dip has a visible reason.
Coffee makes you feel more alert, not have more energy. Reps shows the two apart, and when the caffeine wears off.

Wear Apple Watch overnight and during workouts and the picture sharpens.
Sleep
Forgot to wear it, or it was charging? Reps says so instead of guessing a score, and shows what it can and cannot tell you about that night.
You can log sleep yourself, so a night without your watch still counts toward your usual and your sleep debt.


REX, your coach
Ask REX whether to train hard and it answers from your own sleep and training load, then offers to build the session. It checks in only at the moments you pick: after a meal, after a short night, after a hard workout.
REX uses Apple Intelligence on your iPhone and Apple’s Private Cloud Compute. Google’s cloud AI is only used if you turn on “Allow Google’s AI for REX”, and you can turn it off any time in How REX thinks. Every answer shows which one replied.

Nutrition
Snap, say or type what you ate. Reps tells you what is left for the rest of the day in a sentence, not just a ring, and counts what Health says you have burned so far.
Every number on a meal says how sure it is: Sure, Likely or Rough. Correct a meal once and Log again logs it your way next time.

Training
Reps tracks how long each muscle group has rested and lines up the next session. Ask for a workout and it is built around how you slept, what you have eaten today and how recovered you are, not a generic template.
On walks and runs, REX coaches you live while you are out there.

Widgets
Interactive widgets let you log from where you already are, and Lock Screen widgets keep today’s numbers one glance away.

From the App Store
Sentences from real App Store reviews, quoted exactly as their authors wrote them.
“My favorite thing about reps is it is a place that conglomerates all of the data my Apple Watch is creating and turns it into useable information for me.”
“I love the nutrition features (snap to analyze, descriptions to help the model understand what you ate, etc) and the summaries are top tier.”
“This app integrates seamlessly with your Health app and gives you a clear, all-in-one view of your workouts and overall health.”
“It replaced my previous 2 apps.”
Also new in 2.0
Your meals and history are backed up to your own iCloud, so a new phone does not mean starting over.
Start a walk or a run and REX coaches you while you move, in short prompts that fit the effort you are actually making.
