This app is a body measurement and body composition tracking tool designed to help users monitor physical progress over time. It allows users to record anthropometric measurements and apply established analysis methods to estimate body composition and related metrics.
The primary purpose of the app is to provide a simple, structured, and privacy-focused way to track body measurements and analyze body composition using scientifically recognized formulas.
It is intended for:
- Fitness tracking
- Body recomposition monitoring
- Research or self-quantification
- Long-term physical progress tracking
1. Measurement Tracking
Users can record a wide range of body measurements, such as:
- Body weight
- Circumference measurements (e.g., waist, hips, chest, arms)
- Skinfold measurements for body fat estimation
Measurements are stored chronologically to allow progress tracking over time.
2. Body Composition Analysis
The app supports multiple analysis methods that use recorded measurements to estimate body composition.
Examples include:
- Skinfold-based body fat estimation methods (e.g., Jackson & Pollock formulas)
- Other measurement-based body composition calculations
Users can choose which analysis methods they want to use, and the app automatically activates the required measurements.
3. Configurable Measurement System
When enabling analysis methods, the app automatically:
- Activates all measurements required for those methods
- Allows users to enable additional optional measurements in the settings
This ensures that the measurement workflow remains minimal but flexible.
4. Progress Monitoring
By storing measurements over time, the app enables users to:
- Track physical changes
- Monitor body composition estimates
- Maintain a historical log of their measurements
5. Measurement Reminders
Optional reminders can be configured to help users maintain consistent measurement routines. Users can select specific weekdays and times for reminders.
Data confidentiality is a core design principle of the app.
- All data is stored locally on the device.
- No measurement data is transmitted to external servers.
- No cloud synchronization is required.
- No user accounts are needed.
This ensures that sensitive personal health and body data remains fully private and under the user’s control.
The app is built around the following principles:
- Privacy-first architecture
- Local data storage
- Transparency of calculations
- Scientific measurement methods
- Minimal and focused user interface
The app provides a private, reliable, and scientifically grounded tool for body measurement tracking and body composition analysis, while ensuring that all sensitive user data remains securely stored on the device itself.
