Simple Yoga
An AI-powered yoga companion that helps practitioners check their form from a single photo — delivering an instant pose score, corrective feedback, and progress tracking, all processed on-device.
Overview
Instant form feedback, built around real practice.
Simple Yoga uses on-device pose detection (Google's MediaPipe) to analyse a yoga pose from a photo in seconds. Beyond a simple score, the app delivers specific, actionable feedback — which joint to adjust, which angle to correct — pose by pose, tailored to a growing library of 20 beginner-to-intermediate yoga poses.
Built as part of the Apposite Labs mobile portfolio, Simple Yoga demonstrates how on-device AI can turn a simple photo into a personal, judgement-free practice companion — without a subscription, a camera feed leaving the device, or a real instructor's fee.
The problem
Solo practice leaves no way to know if your form is right.
Practising yoga without a teacher in the room is common — and hard to trust. Existing options fall short in different ways:
The need was clear: a way to check form privately, instantly, and specifically enough to actually improve. Simple Yoga was built to meet all three.
Key features
Everything the app does.
On-Device Pose Scoring
A single photo returns a 0–100 score for the chosen pose, measured against the precise joint angles that define correct form — mountain, tree, warrior, downward dog, and 16 more.
Targeted Corrective Feedback
Every score comes with specific, plain-language tips — "bend your front knee further," "lift your hips higher" — tied to exactly which part of the pose needs adjusting.
Pose Library
A browseable library of beginner and intermediate poses, each with a reference photo, difficulty rating, and step-by-step instructions before you practise.
Progress Tracking
Every attempt is saved locally on-device, building a visual history per pose — best score, most recent attempt, and a photo timeline you can revisit.
Shareable Results Cards
Every scored attempt can be turned into a branded, downloadable results card — pose name, photo, and score — ready to share or save to your camera roll.
Practice Reminders
A gentle, optional recurring nudge to check back in with your practice, fully controllable from Settings.
Design philosophy
Encouraging, not clinical.
Simple Yoga is designed to feel like a calm companion, not a fitness tracker. Every screen is built around warmth, clarity, and confidence. The interface prioritises:
- — A warm, editorial visual language over a "tech" aesthetic
- — Feedback that guides, never shames
- — Real photography over stock icons and gradients
- — Judgement-free framing at every step
The app never claims to replace a qualified instructor. It gives a private, instant read on form, so a solo practitioner can adjust with confidence — the rest is left to their own body and, where needed, real guidance.
The core flow is four steps:
- 01 Open the app
- 02 Choose a pose from the library
- 03 Take or upload a photo
- 04 Get an instant score with specific tips to improve
