iCloud backup
Your meals and history are backed up to your own iCloud, so a new phone does not mean starting over.
Reps 2.0on the App Store
Know how much energy you have, and why. 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
Last night’s sleep sets how much you start the day with, measured against your own usual. Moving around draws it down, and a workout shows its own cost on the curve.
Caffeine sits 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.

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.
If your iPhone supports Apple Intelligence, REX answers on your device and steps up to Apple’s Private Cloud Compute for heavier questions. It uses Google Cloud as a backup only if you allow it. Every answer shows which one replied. How REX handles your data

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.

iPhone Duo
Unfold and Reps uses both sides: your day on one, the detail behind it on the other.

Desktop AI for Mac
