You coach. FitX tracks. No middleman between you.

Full export, not summaries.

Elite-tier athletes export their complete training history as structured JSON or CSV — every session, every RPE entry, every Critical Force measurement, sleep and HRV logs, lever progression steps, MEV/MAV/MRV compliance. Straight from their phone to your inbox. Schema stable across versions. Pull it into your coaching spreadsheet, Notion database, or whatever you already use.

CSV available for anyone allergic to JSON. Same fields, flat structure, Excel-safe.

Because it’s as important as what we do.

No data sales.

Not to insurers, not to sponsors, not to aggregators. No line item of our revenue is data. The only money moving is from your athlete to us, for the app.

No unsolicited leaderboards.

We don’t surface "top climbers in your gym" or "this week’s heaviest squat" to athletes who didn’t opt in. Training logs are private by default and stay that way.

No coach marketplace.

FitX isn’t building a platform where coaches bid for athletes or collect leads. You already have the relationship. We don’t get in the way of it.

No AI coach.

We don’t replace you with an algorithmic coach, and we don’t let your athletes replace you with one either. The app prescribes load, not programs. Programming is your job.

If you need any of these, FitX isn’t the right app. That’s a deliberate narrowing, not a roadmap item.

Five steps. No CRM.

1. 01

   Your athlete installs FitX and upgrades to Elite.

   Install is free. Elite unlocks export and is the tier coaches need. See /pricing for the current rate.

2. 02

   In Profile → Coach Integration, they enter your coaching email.

   No login for you. No invite flow. Just your email on their device.

3. 03

   They choose export cadence: weekly, monthly, or on-demand.

   Default is monthly. Enough for longitudinal coaching, not so frequent it becomes noise.

4. 04

   You receive a signed export email with JSON + CSV attachments.

   Signed so you know it’s actually from FitX and not a spoofed sender. Same format every time.

5. 05

   You coach. They train. FitX disappears between the two of you.

   No coach dashboard. No messaging feature. No comment threads inside the app. Those belong in whatever tool you and your athlete already use.

We aren’t building a coaching product. We’re building the training tool underneath one.
