Sit tall, without thinking about it. Plumb is a calm, private posture-awareness companion. It learns the comfortable "tall" you set for yourself, gently notices when your head drifts forward, and nudges you to ease back β€” at your desk, or hands-free through your AirPods. A prompt to notice, not a verdict. Plumb learns your neutral, not a textbook ideal β€” and the fastest way to lose your trust would be to overclaim, so it stays plain-spoken about what it can and can't do. TWO WAYS TO USE IT Hands-free with AirPods β€” the everyday mode. Plumb reads your head position from compatible AirPods or Beats, so your phone can stay pocketed or locked. A soft tone cues you the moment you drift past your own threshold, and goes quiet the instant you ease back. Camera at your desk β€” the screen-attended alternative. The front TrueDepth camera reads your head position at desk distance β€” and your shoulders when they're in view. Frames are processed in the moment and immediately discarded β€” never previewed, saved, or uploaded. It can't see your lower back, and we won't pretend otherwise. CALM BY DESIGN β€’ A gentle nudge β€” a soft tone, a tap, or both. It gets slightly more insistent on a long slump, and stops the moment you ease back. β€’ Breathing and small shifts inside your neutral zone never count. β€’ A "held tall" timer tracks your time in a comfortable position. β€’ A stylised living figure reflects how you're holding your head β€” no camera image or video is ever stored or shown back. β€’ Insights answers one honest question: am I improving? A clear average, an honest change once there's enough history, and quiet days left as blank space, never guessed. β€’ Learn β€” six short, evidence-anchored reads on why noticing your posture matters, each with its limits stated plainly. YOUR POSTURE NEVER LEAVES YOUR PHONE β€’ Everything is analysed on your device. There are no Plumb servers and no backend β€” there's nothing to send. β€’ No account, ever. No sign-up, no email, no login. β€’ No ads, no trackers, no analytics, no third-party SDKs. β€’ iCloud sync is off by default and opt-in; it goes only to your own private iCloud. β€’ Apple Health is write-only β€” Plumb can log a Mindful Minutes session and never reads your health data. SIMPLE, TIME-METERED PRICING Time is the only free meter β€” no feature walls. Free, forever: one check-in a day across both modes, up to five minutes, with the full nudge experience, the pain log, your two-week Insights window, and the whole Learn library. Plumb+ unlocks unlimited check-ins at any length, the hands-free Live Activity on your Lock Screen and Dynamic Island, Month and Year Insights, and CSV / PDF export. Plumb+ comes three ways: Weekly, Annual (with a 7-day free trial), or a one-time Lifetime unlock. You'll always see the exact price for your region on the subscription screen before anything is charged. Subscriptions are billed through your Apple Account; cancel anytime in App Store β†’ Subscriptions. Trial eligibility is decided by Apple. Made with care, and localised into nine languages. Plumb is a wellness and posture-awareness tool, not a medical device. It does not diagnose, treat, cure, or prevent any condition. If you have a health concern, please speak to a qualified professional. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Posturely: Posture Reminder turns your iPhone into a private desk posture coach. Position it near your monitor, complete a quick calibration, and receive a gentle nudge only when posture drift persistsβ€”not for every small movement. Why Posturely? Long desk sessions make it easy to lean, slouch, or lose alignment without noticing. Constant reminders quickly become annoying. Posturely learns your natural seated baseline and focuses on persistent changes, helping you build awareness without interrupting your flow. What you can do Live posture monitoring β€’ Use the front camera to monitor head position, shoulder balance, torso alignment, and centering. β€’ Calibrate to your natural sitting position instead of relying on a one-size-fits-all pose. β€’ Place your iPhone above or below your monitor and select the matching setup. β€’ See a live alignment score and clear posture signals during each session. Smart, customizable nudges β€’ Receive visual, haptic, or sound feedback when posture drift continues. β€’ Adjust sensitivity, persistence time, cooldown, sound, and haptic strength. β€’ Keep small natural movements from triggering unnecessary reminders. β€’ Enable optional time-based reminders for periods when your iPhone is locked. Private by design β€’ Posture analysis runs on your iPhone. β€’ Camera frames are never saved to your photo library or uploaded by Posturely. β€’ Use Private View to replace the camera preview with a simple posture silhouette. β€’ Blackout mode keeps live monitoring active while making the screen almost black. Insights that make progress visible β€’ Review weekly alignment scores, desk time, and posture debt. β€’ See session length, nudge frequency, and when posture usually begins to drift. β€’ Track daily progress and recent trends in a simple, modern dashboard. β€’ Keep compact session history on your device and delete it whenever you choose. Stay motivated β€’ Earn XP across 50 levels as you complete focused desk sessions. β€’ Build a daily streak with at least 10 minutes of monitored desk time. β€’ Follow an achievement path for milestones such as quiet sessions, strong alignment, consistency, and total desk time. β€’ Work toward a 30-minute daily goal and see your next milestone at a glance. How it works 1. Place your iPhone above or below your monitor with your head and shoulders visible. 2. Choose the matching camera position and calibrate your natural baseline. 3. Start a desk session and work normally. 4. Review your score, insights, streak, levels, and achievements. Who it’s for Posturely is designed for office workers, remote workers, students, creators, developers, and anyone who spends long periods at a desk and wants to build more mindful desk habits.
