Body Measurement Apps Compared

Five popular body tracking apps for iPhone, objectively compared. Which one actually shows your progress — and which ones just show numbers?

1

Me ThreeSixty

Me ThreeSixty uses your iPhone camera to create a 3D body scan. You take front and side photos, which are uploaded to servers for processing. The app generates a 3D avatar that you can rotate and compare over time. Me ThreeSixty tracks body measurements extracted from the scan and provides basic health metrics like BMI.

Strengths

  • Photorealistic 3D body scan
  • Visual body comparison over time
  • Free with in-app purchases
  • Extracts measurements from photos automatically

Limitations

  • Requires body photos uploaded to servers
  • Account registration required
  • Dependent on lighting and camera conditions
  • No AI body prediction or past reconstruction
  • For measurement-based tracking without uploading photos, Contura offers an alternative approach
2

ZOZOFIT

ZOZOFIT is a photo-based 3D body scanning app available on iOS and Android. It captures a 360-degree body scan using your phone camera, tracking 12 key body areas. The free tier includes body scans, measurements, BMI, and trend graphs. A premium tier at $2.50/month adds personalized assessments and AI food scanning. ZOZOFIT also offers the ZOZOSUIT, a hardware garment for enhanced scanning accuracy.

Strengths

  • 360-degree body scanning
  • Tracks 12 key body areas
  • iOS and Android support
  • Food journal and goal setting
  • Optional ZOZOSUIT for enhanced accuracy

Limitations

  • Requires photo uploads to cloud servers
  • Account registration required
  • Premium tier at $2.50/month for full features
  • Requires controlled lighting for accurate scans
  • For on-device processing with no photo upload, Contura provides a privacy-focused alternative
3

Happy Scale

Happy Scale is a weight tracking app that focuses on trend analysis. It uses moving averages and exponential smoothing to show your weight trajectory, cutting through daily fluctuations. Happy Scale projects future weight based on your trend line. It integrates with Apple HealthKit and provides a clean, simple interface for monitoring weight over time.

Strengths

  • Excellent weight trend analysis
  • Moving average smooths daily fluctuations
  • Weight projection feature
  • Simple, focused interface

Limitations

  • Only tracks weight — no circumference measurements
  • No 3D body visualization
  • No body composition metrics beyond BMI
  • Predictions are weight numbers only, not visual
  • For full 3D body visualization with circumference tracking, Contura offers a more comprehensive approach
4

MyFitnessPal

MyFitnessPal is one of the most popular health apps, primarily focused on calorie tracking and food logging. It includes a large food database, barcode scanner, and recipe importer. MyFitnessPal also tracks weight and basic exercise. It is designed as a comprehensive nutrition tool rather than a body measurement or visualization app.

Strengths

  • Massive food database (14M+ foods)
  • Barcode scanner and recipe importer
  • Large user community
  • Integrates with many fitness devices

Limitations

  • No body visualization or 3D model
  • No circumference measurement tracking
  • Focuses on calories, not body shape
  • Account required, data processed server-side
  • If you want to see your body shape rather than just track calories, Contura provides 3D body visualization
5

Model My Diet

Model My Diet is a body visualization tool that creates a 3D avatar based on your measurements. It allows you to adjust body parameters to simulate weight loss or gain and see a visual preview. The app provides a straightforward way to visualize body shape changes from basic inputs.

Strengths

  • Visual body model from measurements
  • Simulate weight loss or gain visually
  • Simple to use

Limitations

  • Limited measurement inputs
  • No AI-powered body prediction
  • Few health metrics calculated
  • No comparison or tracking tools
  • For AI-powered body prediction and 15+ health metrics, Contura offers a more feature-rich alternative

Which App Fits Your Goal?

You want to see your body change in 3D

Me ThreeSixty and ZOZOFIT offer photo-based 3D scanning if you're comfortable taking body photos. For measurement-based 3D visualization without photos, Contura creates a parametric 3D model from circumference measurements with no camera required.

You want maximum privacy

All five apps listed above either require account registration, upload data to servers, or process data in the cloud. For fully on-device processing with no account, no photo uploads, and no backend servers, Contura takes the strongest privacy stance in this category.

You want to track nutrition

MyFitnessPal is the clear choice for calorie tracking and food logging. It has the largest food database and barcode scanner. Pair it with a body visualization app to see the physical results of your nutrition tracking.

You just want to track weight

Happy Scale provides the best weight trend analysis with moving averages and smooth projections. If you only care about the number on the scale and want sophisticated trend analysis, Happy Scale does this well.
