How can we help
with Postural?

Postural Age is your chronological age plus a penalty contributed by each of five measurable postural deviations — forward head posture (CVA), rounded shoulders (FSA), trunk lean (SHK), shoulder asymmetry (Sym), and lateral head tilt (Tilt).

Each marker can add up to 2–6 years depending on severity, for a maximum total penalty of +20 years. It's a wellness trend indicator designed to give you a motivating, trackable number — not a clinical diagnosis.

• CVA (Craniovertebral Angle) — measures forward head posture. Max +6 years.
• FSA (Forward Shoulder Angle) — measures how far your shoulder rolls forward. Max +5 years.
• SHK (Shoulder-Hip-Knee Alignment) — measures trunk lean in the sagittal plane. Max +4 years.
• Sym (Shoulder Symmetry) — measures left-to-right shoulder height difference. Max +3 years.
• Tilt (Lateral Head Tilt) — measures sideways head tilt from horizontal. Max +2 years.

At least 3 of the 5 markers must be measurable from your photos for a valid scan. If fewer are detected, you'll be asked to retake the photo.

Postural uses Apple Vision Framework's 2D body pose detection to locate 13 body landmarks. The scoring thresholds are grounded in five peer-reviewed physiotherapy research papers.

Accuracy is affected by lighting, phone positioning, clothing, and whether you're standing perpendicular to the camera. For best results: stand 2–3 meters from the phone on a flat surface, wear fitted clothing, and ensure even lighting with no strong backlight.

Treat your score as a consistent trend indicator across time, not an absolute clinical measurement. Postural Age is not a medical diagnosis.

A scan result requires at least 3 of the 5 posture markers to be measurable with sufficient confidence. This can fail if:

• The photo is blurry or taken in poor lighting
• You're too close or too far from the camera
• Loose clothing obscures key landmarks (hips, shoulders, ears)
• You weren't standing perpendicular to the camera for the side view

If this keeps happening, try a brighter environment, wear fitted clothing, and ask someone to help position the phone for you.

No. All posture photos are stored exclusively on your device. Each file is flagged at the filesystem level to exclude it from iCloud backup — enforced by an automated test on every build. Your photos are never uploaded to any server.

Deleting the app removes all stored photos permanently.

Postural sends the following data externally:

• Anonymous analytics events via Firebase (e.g. "scan completed") — no photos, no scores, no personal identity.
• Crash reports via Firebase Crashlytics — device model, iOS version, and a stack trace. No personal data.
• Account data (if signed in) — your scan scores are stored in Firebase Firestore, associated with your Google account, so you can preserve history across reinstalls.
• YouTube video traffic — when you play an embedded exercise video, your device connects directly to YouTube's servers. We don't send your posture data to YouTube.

Your posture photos are never transmitted. See our Privacy Policy for full details.

You can delete your account at any time from Settings → Delete Account inside the app. This permanently removes your Firebase account and all associated scan history from our servers.

Local data (photos, local history) is removed when you uninstall the app.

If you need help, email support@srstech.in and we'll process your deletion request manually.

After each scan, Postural analyzes which of your five posture markers scored highest and selects the most relevant stretches from a library of 19 curated exercises. Each stretch targets a specific postural issue.

Your routine is reassembled after each new scan, so it evolves as your posture changes over time.

Day 7 shows your baseline and consistency streak — but meaningful postural change takes longer than one week. Per a 2024 BMC meta-analysis, 21 minutes of mobility work over 7 days produces near-zero measurable structural change.

Day 28 is where real improvement typically becomes visible in your score. Stick with it — consistency is the only variable you control.

No. Postural is a consumer wellness app, not a medical device. Postural Age is a geometric trend indicator — it does not account for pain, strength, hypermobility, or individual anatomy. It cannot diagnose or treat any condition.

If you have posture-related pain or dysfunction, please consult a qualified physiotherapist or healthcare provider.

Postural is currently in active development with a target launch of late 2026. Join the waitlist on the Postural page to be notified the moment it's live on the App Store.

Postural requires iOS 18.0 or later. It is designed for iPhone. iPad support may follow in a future update.
