# PoseAlign

> PoseAlign is a free AI posture checker for Android. It uses front and side photos to show pose landmarks, alignment measurements, and a PDF posture report.

The official website and default English homepage are at https://posealign.com/. The redesigned app is free to use, with no paid plan or subscription. The website describes the Android app; posture analysis takes place in the app, not in the browser.

In the app, choose Advanced check, add one front and one side full-body photo, and generate a report. Front-view measurements include head tilt, shoulder level, clavicle angle, chest symmetry, arm position, waist angle, pelvic level, knee alignment, foot position, and left and right Q angles. Side-view measurements include forward head angle and pelvic tilt. Reports can be exported as PDF files.

The website's screenshots and measurements are examples. The downloadable PDF and walkthrough video are labeled as earlier examples and can differ from the latest app screenshots. PoseAlign supports posture awareness and general wellness, not medical diagnosis. Photo angle, framing, lighting, clothing, and how a person stands can affect the estimated measurements. Support: support@posealign.com.
