Units and your data

Video, 14 seconds, with narration and captions. Units, rest timer, grading, sounds.

Switch between kilograms and pounds

Section titled “Switch between kilograms and pounds”

You pick a unit during first-run setup, and you can change it at any time.

  1. Open the Locker tab.
  2. Open Settings.
  3. Find Units, near the top just under Training, and choose Kilograms or Pounds.

Every weight in the app then shows in your chosen unit. That includes the set card, your PRs, your history, and the numbers on screen when you load the bar.

What happens to your old numbers

Section titled “What happens to your old numbers”

Nothing is rewritten. The app keeps every weight in kilograms behind the scenes and converts it only when it shows you a number. If you switch from kilograms to pounds, your history stays exactly as it was and simply reads differently. You can switch back whenever you like without any rounding creeping into your records.

Peeking at the other unit during a session

Section titled “Peeking at the other unit during a session”

The session screen has a kg/lb button in its toolbar. It shows what that screen would look like in the other unit, which is handy when you want to know what 102.5 kg comes to in pounds. It is a preview only: it ends when you leave the session, it does not change your Settings, and while it is on the working weight cannot be edited. To change the unit for good, use Settings.

Where your data lives

Section titled “Where your data lives”

Your sessions, sets and records are stored on your device, so the app works without a connection. The Data & Privacy screen shows where your training data is kept.

Bar Trace video clips are handled separately. They save to your photo library either way. You can choose in Data & Privacy whether they also sync to iCloud so your other devices can play them, and the screen shows how much space your clips use.
