Help with Perch: Posture Coach

What do I need to use Perch?

Perch works with an iPhone and a pair of AirPods that have built-in motion sensors — such as AirPods Pro, AirPods (3rd generation) or later, and AirPods Max. It reads head-motion from your AirPods to detect posture, so those sensors are required for live coaching. You can preview how it works on iPhone alone using the built-in "See how it works" demo.

Perch isn't detecting my posture or nudging me

• Make sure your AirPods are in your ears and connected to your iPhone.
• Confirm Motion & Fitness access is on (see below) — coaching can't run without it.
• Recalibrate your upright baseline in Settings → Baseline → Recalibrate while sitting tall.
• If nudges feel too rare or too frequent, adjust the sensitivity sliders (see "Make the nudge gentler or stronger").

How do I turn on Motion & Fitness access?

Open the iPhone Settings app, go to Privacy & Security → Motion & Fitness, and turn on the switch for Perch (make sure "Fitness Tracking" at the top is also on). Perch also has a shortcut to this screen if you ever land on the "Turn on Motion access" page inside the app.

Coaching doesn't start automatically when my AirPods connect

Automatic start is an optional feature you set up once. In Perch, open Settings → Auto-start when AirPods connect and follow the short guide to create a personal Shortcuts automation. Until that's set up, you can start coaching manually from the app's home screen. Perch works fully either way.

Make the nudge gentler or stronger

Everything is adjustable in Settings:

• Slouch threshold — how far your head must drop before it counts as slouching (lower = stricter).
• Grace period — how long you can be slouched before the nudge begins.
• Escalation — how quickly the nudge ramps from a first cue to full.
• Nudge tone — choose the sound, or a silent (audio-ducking only) option, and preview it.

Managing your subscription

Subscriptions are handled by Apple. To view, change, or cancel your plan, open Settings → [your name] → Subscriptions on your iPhone, or tap Manage subscription in Perch's Settings. If you were charged after a free trial, the trial converts to a paid subscription unless you cancel at least 24 hours before it ends.

Restoring a purchase

If you've subscribed before (for example on another device or after reinstalling), tap Restore on the subscription screen to re-activate your access. Make sure you're signed in with the same Apple ID you used to subscribe.

Your privacy

All posture processing happens on your device, and Perch collects no personal data. For the full details, see our Privacy Policy.
