How can we help?

BFF - Be Fit and Functional is an AI-powered accountability coach that helps you reach your health and fitness goals. You pick an AI persona (Bro, Bestie, Queen, or Ride or Die), set your goals, and your BFF checks in with you daily - tracking your diet, celebrating wins, and calling you out when you slip.

Unlike generic fitness apps, BFF focuses on accountability. It's not just logging data - it's having a best friend in your corner who actually keeps you honest.

Bro - High energy, zero tolerance for excuses. Great if you want someone to push you hard.

Bestie - Warm, supportive, and honest. Perfect if you want encouragement with a dose of real talk.

Queen - No nonsense, high standards. Ideal if you respond well to high expectations and sharp motivation.

Ride or Die - Day one energy, always in it with you. Best if you want consistency and loyalty above all.

You can switch personas at any time from your settings.

BFF is currently available on iOS (iPhone). An Android version is on our roadmap. Email us at support@bff-app.me to join the Android waitlist.

BFF requires iOS 16 or later. We recommend keeping your iPhone updated to the latest iOS version for the best experience.

The free version includes limited BFF Chat messages, basic diet tracking, access to one AI persona, and your dashboard overview. It's a great way to experience BFF before committing to Premium.

BFF Premium unlocks the full experience: unlimited BFF Chat, advanced diet and macro tracking, all 4 AI personas, progress charts and insights, the Wins Wall, and priority support.

Premium is $9.99/month or $59.99/year (saving you 50% vs monthly).

Since BFF subscriptions are managed through Apple, you cancel through your iPhone settings. Open Settings, tap your name, tap Subscriptions, find BFF, then tap Cancel Subscription. Your Premium access continues until the end of your current billing period.

All purchases are processed through the Apple App Store. Refund requests are handled by Apple directly at reportaproblem.apple.com.

If you're having an issue that led you to request a refund, please reach out to us at support@bff-app.me first - we'd love to help resolve it.

Try these steps: go to Settings in BFF and tap Restore Purchases, then force-close and reopen the app. Make sure you're signed into the same Apple ID used for the purchase. If none of those work, email us at support@bff-app.me.

You can delete your account in the app via Settings - Account - Delete Account, or visit our account deletion page. All your data is permanently deleted within 30 days. Note: deleting your account does not automatically cancel an active subscription - cancel that separately through iPhone Settings first.

Yes. Your health and fitness data is encrypted both in transit and at rest. We never sell your data to advertisers or third parties. Read our Privacy Policy for full details.

BFF can optionally connect to Apple Health to read activity and nutrition data. This is entirely opt-in. You can revoke access at any time through iPhone Settings - Privacy & Security - Health - BFF.

BFF is powered by Claude, an AI model built by Anthropic. Each persona (Bro, Bestie, Queen, Ride or Die) is a distinct character built on top of Claude, giving each one a genuinely different voice, tone, and coaching style.

Yes. Your conversations with your BFF are private and treated with the same sensitivity as health data. We do not use your personal conversations to train AI models.

No. BFF is a wellness accountability tool, not a medical service. Nothing in the app should be taken as medical, nutritional, or clinical advice. Always consult a qualified healthcare professional before making significant changes to your health routine.
