HealthX is an all-in-one health and fitness app that brings adaptive training, nutrition and macro tracking, recipe import, shopping lists and an AI coach onto one screen. It works in any browser as a web app, with an iOS app that adds Apple Health and Apple Watch sync. You can start free in about two minutes, no credit card.

You pick a goal at onboarding — a weights/cardio split or Hyrox race prep — and HealthX builds a multi-week mesocycle with periodised phases. Sessions prescribe exercises and load based on your recent history; you log each set's weight, reps and reps-in-reserve, and the app tracks your estimated 1RM and detects PRs. For Hyrox, you enter a race date and it plans backwards through base, build, peak and taper. You can swap exercises, customise your split and reschedule missed sessions.

You set macro targets at onboarding, then log food by typing it in, scanning a barcode, picking from the meal library, or snapping a photo that Claude estimates into macros (photo estimate is a paid feature). Recipes import from any URL, or you can paste an Instagram or TikTok caption and the app pulls out the ingredients and macros. From your meal plan, HealthX builds a shopping list with regional price estimates.

Atlas is an AI coach powered by Anthropic's Claude. It gives a weekly recap of your training, nutrition and weight trends, sends daily nudges like a protein gap or a missed session, and answers questions in a chat that knows your plan, logs and goals. When it suggests a change to your calories, macros or training, it shows it as a proposal you choose to apply — never a silent edit. Atlas is part of the paid tiers.

Crews are private, invite-only accountability groups with a shared feed for posts and reactions. Weight is only ever shared as a relative change, never an absolute number. Your data lives in a cloud database with an offline cache on your device, sent over TLS with hashed passwords. We don't sell your data or work with advertisers, and you can export everything or delete your account at any time.

There's a free tier with basic training and nutrition logging, and paid tiers that unlock Atlas, recipe and meal tools, shopping lists, photo food estimates and custom training — every new account gets a 14-day trial. On iOS it syncs with Apple Health and Apple Watch for steps, workouts, heart rate and sleep, and barcode lookups use Open Food Facts. Billing runs through Stripe.

No. HealthX is for training, nutrition and general fitness — not diagnosis or treatment. It isn't a substitute for advice from a doctor or dietitian.
