Your data lives on your device

Open Rackd, skip the welcome flow, and start lifting. There is no account to make and no email box to fill. Your training history lives on the phone in your pocket, and that is the whole story.

Local-first, by design

Rackd is built on WatermelonDB, a local database that runs inside the app on your device. When you log a set, the weight, reps, RPE, and timestamp are written to that database before anything else happens. No round trip to a server, no spinner waiting on a network call. The set is saved the moment you tap the check.

Every workout, every program, every PR, every Coach Note is the same. It writes locally first. The app stays fast on subway rides, in basement gyms with no signal, on flights, and at home with the router rebooting. The data is already where it needs to be.

This is not a feature that got added later. It is how the app was put together from the first commit. Local-first from day one, not as a selling point but because it is the right way to build it.

No signup required

You do not need an account to use Rackd. The welcome flow has a sign-in option for Cloud Sync and a Skip button next to it. Tap Skip and you are in. The full app opens up, all 15 programs, all 11 progression systems, all 453 exercises, every chart in the Progress tab. Nothing is held back behind an email gate.

If you decide later that you want sync across two phones or a backup off the device, you can add an account from Settings whenever you like. The data already on your phone moves with you.

Cloud Sync is optional

Cloud Sync is the one feature that talks to a server, and it is off by default. It exists for lifters who carry a phone and a tablet, or who replace a device once a year and want their history to follow. The how-it-works page for Cloud Sync covers the details in its own article.

Until you turn it on, nothing about your training leaves the phone. No telemetry, no analytics tied to your name, no third-party tracker reading your reps. Your training data belongs to you.

That's not changing.
