Paice

pace + ai

Your workout should know how you slept.

Paice reads your recovery, adjusts today's session to match it, and moves your food targets with the training you actually did.

The idea

One loop, not three trackers.

Recovery, training and nutrition are one system in your body. In your phone they live in three apps that never talk. Paice is the connection between them.

01

Recovery sets the training

Sleep, HRV and resting heart rate from Apple Health decide how hard today should be, before you pick up the bar.

02

Training sets the food

A heavy leg day and a rest day don't get the same number. Calories and protein follow the load that caused them.

03

What you did shapes tomorrow

Every set you log and every night you sleep feeds the next plan. It learns from you, not from a formula.

The gap

Everyone owns one leg of the loop.

The apps people already use are good at what they do. None of them can see the other two parts, so you end up being the integration.

Workout apps

Program a hard session without knowing you slept five hours.

Recovery wearables

Know you slept five hours, and can't change your session.

Diet apps

Set the same target for a leg day and a rest day.

Paice

Sees all three, and makes the call so you don't have to.

The logging

A set in two taps.

Mid-set, with one sweaty thumb, the log has to keep up. Paice uses the layout lifters already read and gets out of the way.

  • Last session in viewThe weight and reps you did last time sit beside every set.
  • Rest timer starts itselfCheck the set and the clock is already running.
  • 1,500 exercises, animatedSearchable by muscle and equipment, each with a short loop of the movement.

The rule

Never a number it can't stand behind.

Food data is only useful if you can trust it. Every entry in Paice shows where its number came from: verified sources by default, and estimates clearly marked as estimates, with one tap to correct them.
