Create an account

You can register with your email address or with Google.

With email

1. Open the app at app.blaksfit.com and choose Sign up.
2. Enter your email and set a password.
3. Tick the required consent checkboxes (terms and privacy) to continue.
4. We email you a 6-digit verification code (OTP). Enter it to confirm your email.

The code expires after 10 minutes. You can request a new one after 60 seconds. If it doesn’t arrive, check your spam/junk folder.

With Google

Choose Continue with Google and pick your account — no separate password needed. You’ll still confirm the consent checkboxes the first time.

Invited by a trainer, gym, hotel or company?

You may not sign up here at all — you’ll receive an activation key or an invite code instead. Follow your persona’s guide:

• Activate as a client
• Join a gym
• Corporate employee onboarding
