Use Rackd on more than one device

Rackd is local-first by design. Every set, every workout, every PR is written to the device you logged it on. That is the default and that is fine. When you want the same training history on a second device, Cloud Sync is the bridge. It is optional, off by default, and you turn it on the same way on every device you want in the loop.

Turn on sync on the first device

Open Settings and tap Sync. If you have not signed in yet, the screen walks you through creating a Rackd account or signing in with one you already use. Pick a sync mode while you are there. Background sync runs while the app is open or when you reconnect. Manual sync waits for you to tap Sync Now. Either is fine, pick the one that matches how you like your apps to behave.

The first sync writes your existing local history up to the server. A long history takes a minute or two. The status indicator shows progress and lands on Up to date.

Sign in on the second device

Install Rackd on the new phone or tablet. Open Settings, tap Sync, and sign in with the same account. The first sync pulls your programs, your workouts, your PRs, your training maxes, your custom exercises. Anything you logged locally on the second device before signing in stays put and gets merged in.

If both devices already had a few workouts logged, the merge keeps both sides. Same workout edited on both before either synced is the only case where a rule has to pick a winner.

How conflicts are settled

Rackd uses last-write-wins at the record level. The version with the newer updated-at timestamp is kept, the older one is replaced. Workouts with a completed status are preserved over partial ones, so a finished session on one device is never demoted by a stale draft on another. Settings always defer to the device you changed them on most recently.

If a real conflict needs your eyes, the app surfaces it in a Resolve Conflicts card on the Sync screen. You pick which side to keep, the rest goes through automatically.

Moving to a new phone

Same flow. Sign in on the new device, let the first sync land, your training history is there. Nothing gets taken away.
