How can we help?

Choose a membership on the website and create your account there. Then download the app and sign in with the same details.

Yes. If you signed up with Apple or Google, use the same button on the app’s sign-in screen. Use the same method every time so you land in the same account.

Tap “Forgot password” on the sign-in screen and we’ll email you a reset link. If it doesn’t arrive within a few minutes, check your spam folder or contact us.

Yes. The app runs on iPhone and Android. Sign in with the same account on each and your training syncs between them.

No. Memberships are bought on candjstrength.com and paid securely through Stripe. The app is sign-in only, so there are no in-app purchases.

Sign in to your account on candjstrength.com and choose a different membership. The change shows in the app next time you open it.

There are two ways:

1. Sign in to your account on candjstrength.com and cancel your membership there.
2. Or email support@candjstrength.com from the address on your account and we’ll cancel it for you.

Monthly renews every month. Yearly is paid once a year and works out at two months free.

Every membership gets the session runner, rest timer, plate loader and offline training. Mini gives you a hand-picked selection of programs. Super matches you to a program from a short form. Max unlocks the full library and the coach, with technique reviews on Silver and Gold and custom programs on Gold.

Yes. Your program, weights and logged sets are stored on your phone. Train with no connection and everything syncs when you’re back online.

Rest starts as soon as you log a set and counts up to the rest set for that exercise. It keeps running if you leave the session or lock your phone, and shows live on the lock screen and in the Dynamic Island.

Choose your bar (15, 20 or 25 kg), your plate type, and whether you have change plates under 5 kg. If a weight can’t be made exactly, the app shows the nearest one you can load.

No ads, no tracking and no analytics. The app only stores what it needs to run your training.

That depends on your membership. Programs you don’t have access to show a lock in the library. Upgrade on the website to open them.

Technique reviews come with Max Silver and Gold. Upload a lift from your camera roll in the app and your coach replies with written feedback. Silver includes 2x per month; Gold is unlimited.

Custom programs come with Max Gold. Fill in the detailed questionnaire and your coach builds a program for you, which then appears in your app.

1. Check you have signal or Wi-Fi and that airplane mode is off.
2. Open the app and leave it on screen for a few seconds so it can sync.
3. Make sure you’re signed in to the same account on every device.

Your sets are safe on your phone in the meantime. If they still don’t sync, contact us.

1. Use the same method you signed up with — email, Apple or Google.
2. Check the email address for typos.
3. Reset your password from the sign-in screen.

1. Make sure you’re signed in with the account you used on the website.
2. Close the app fully and open it again.

If it’s still not there after a few minutes, email us with the address you signed up with.

1. Check notifications are allowed for C&J Strength in your phone’s settings.
2. In the app, check the notification switches are on for what you want — coach replies, technique reviews, new programs, rest timer.
3. Turn off Focus or Do Not Disturb, or allow the app through it.

Email support@candjstrength.com from the address on your account and ask us to delete it. We’ll remove your account and training data and confirm by email when it’s done.

If you have an active membership, cancel it first so you’re not charged again.

Only what the app needs to run your training: your account details, your programs and the sets you log. See the terms and privacy policy for the full detail.
