Questions on Parameter

Do I need an Apple Watch?

Mon, 01 Jan 0001 00:00:00 +0000

No. Everything runs on the phone. The watch is recommended, since mirroring, haptics, and wrist logging are a big part of the experience, but it is never required. On a paired FTMS machine you get live speed, distance, and grip heart rate with no watch at all.

What does the $1/month actually gate?

Mon, 01 Jan 0001 00:00:00 +0000

Only the AI connection. Logging, execution, the watch app, machine control, history, and export are free, and stay free.

What exactly can my AI see and do?

Mon, 01 Jan 0001 00:00:00 +0000

It can read your profile, equipment, and workout history, and write plans and workouts. It can never write your logs, your profile, or your equipment. The boundaries are per-tool and hard-coded.

What happens if the app crashes mid-workout?

Mon, 01 Jan 0001 00:00:00 +0000

Nothing is lost. Every check-off and transition is saved to disk before the screen advances, so reopening offers to resume or save as partial, and the recovered HealthKit session reattaches with all its samples.

Which machines work?

Mon, 01 Jan 0001 00:00:00 +0000

Bluetooth FTMS-compatible treadmills, bikes, and rowers. For everything else, the console table flattens any interval workout into numbered steps you key in by hand.

How do I disconnect an AI?

Mon, 01 Jan 0001 00:00:00 +0000

Settings → AI connection → Revoke, per client. It takes effect in about a minute. New connections trigger a “Was this you?” alert, so nothing connects quietly.

How does the trial work?

Mon, 01 Jan 0001 00:00:00 +0000

14 days, the full app including the AI connection. Apple shows the price, $1/month, before the trial starts and notifies you before it converts. No card details go to us; it’s a standard App Store subscription.

The watch isn't syncing.

Mon, 01 Jan 0001 00:00:00 +0000

Open Parameter on both devices and mirroring resumes automatically. If it doesn’t, check both are signed into the same Apple ID and that iCloud for Parameter is on.

Which AIs work?

Mon, 01 Jan 0001 00:00:00 +0000

Claude, ChatGPT, Gemini, Grok, Perplexity, Microsoft Copilot (through a Copilot Studio agent), and any client that speaks MCP. Capabilities and setup differ per client; see the connect-your-AI guide for setup steps and the Why Parameter page for what that means in practice.

Will Parameter start or stop my treadmill?

Mon, 01 Jan 0001 00:00:00 +0000

Never. It adjusts speed, incline, resistance, and power, but the machine starts and stops only when you do it. The one Stop button in the app is gated behind an explicit confirmation.

Can Parameter's developer see my data?

Mon, 01 Jan 0001 00:00:00 +0000

No, not even in principle. Your data lives in your iCloud, and Parameter runs no workout database. The full story is on the Privacy page.

Do I need a paid AI subscription?

Mon, 01 Jan 0001 00:00:00 +0000

Not necessarily. Claude’s free plan allows one custom connector, which is all Parameter needs. ChatGPT and Perplexity gate connectors behind paid plans. If you already pay for an AI you’re set; if not, Claude’s free tier is the way in.

How do I cancel?

Mon, 01 Jan 0001 00:00:00 +0000

Settings → your Apple ID → Subscriptions → Parameter → Cancel. Same as every App Store subscription. No email, no retention flow, no “are you sure” survey.

My AI can't see my workouts.

Mon, 01 Jan 0001 00:00:00 +0000

Check the connector is enabled in your AI client, then check Parameter → Settings → AI connection shows the client as connected. If in doubt: revoke and re-add. It takes a minute.

What if I change the speed on the console myself?

Mon, 01 Jan 0001 00:00:00 +0000

Parameter follows your override and records it as a deviation. It never fights you for the controls.

Can my machine's console show my heart rate?

Mon, 01 Jan 0001 00:00:00 +0000

Often. Parameter can broadcast your wrist heart rate to the console’s chest-strap pairing menu, even on machines with no FTMS support. It works with many consoles, not every one; some that accept real chest straps still won’t pair with the broadcast.

Does it work without iCloud?

Mon, 01 Jan 0001 00:00:00 +0000

The app keeps working locally: build, run, and log workouts as usual. Plan sync between devices and the AI connection pause until iCloud is back.

Starting over with a connection.

Mon, 01 Jan 0001 00:00:00 +0000

Remove the connector in your AI client, revoke it in Parameter (one tap), then add the URL fresh.

What about refunds?

Mon, 01 Jan 0001 00:00:00 +0000

Apple handles App Store refunds directly; request one at reportaproblem.apple.com. We can’t process them ourselves, but at a dollar, the stakes are low.

What happens to my data if I stop paying?

Mon, 01 Jan 0001 00:00:00 +0000

Nothing. It’s your iCloud; we couldn’t hold it hostage if we wanted to. The AI connection pauses; logging, execution, history, and export keep working, free.
