How Can We Help?

Iron Chapter is an AI-powered fitness and nutrition app. It combines a personal AI coach (Pulse), smart meal plans, intelligent workout programming, food logging, wearable integration, and detailed progress analytics — all in one app.

Yes. Free includes core food and workout tracking, weight, sleep and water logging, and basic Progress. It does not include an ongoing allowance for AI Coach chat hosted by Iron Chapter, and no additional AI chat trial is provided after the applicable trial ends.

Pro adds advanced features and supported Connected AI (MCP); it does not by itself include AI Coach chat hosted by Iron Chapter. AI Pro includes Pro features and up to 100 Coach messages per day. Other AI features have their own limits.

Legacy purchases that include both Pro and AI Pro retain that access. An app-provided welcome Pro period is separate from a store subscription trial and does not automatically charge you or grant AI Pro. Store trials and introductory offers apply only when the store confirms the offer and your eligibility.

Iron Chapter is launching on both iOS and Android. Join the waitlist at theironchapter.com to be notified when the app is available for download.

Connection availability depends on your platform and plan. Fitbit connection is deferred for the Android launch; manual logging and saved history remain available. Use the connections enabled in your app, and check their sync status before relying on synced data.

Pulse can help with fitness and nutrition questions and prepare food or workout entries from what you tell it. Review the proposed details and confirm the save before treating an entry as logged. Verify the saved entry and totals in the app. Hosted Coach access and limits depend on your plan.

Iron Chapter uses an 8-tier nutrition lookup chain spanning verified local databases, Open Food Facts, Edamam, FatSecret, USDA FoodData Central, and AI estimation. Each lookup is cross-validated with physics checks. While we strive for accuracy, all nutritional values should be treated as informed estimates.

Yes, you can cancel anytime through your Apple App Store or Google Play Store subscription settings. Your Pro features will remain active until the end of your current billing period. After that, your account reverts to the Free tier — no data is lost.

You can delete your account from the Profile settings in the app, by emailing [email protected], or by using the web request page at theironchapter.com/delete-account. We will delete your personal data within 30 days of the request.

Your data is stored on Supabase with row-level security, meaning each user can only access their own data. All data is encrypted in transit and at rest. We do not sell your personal data. See our Privacy Policy for full details.
