Formetrix is built around continuity. Your measurements, trends, and visual documentation become more meaningful as they accumulate — and Profiles & History is where that long‑term picture lives.
A profile represents a single body, context, and history. All measurements, estimates, visual documentation, and insights belong to a specific profile.
This allows Formetrix to stay structured, consistent, and meaningful over time.
What Is a Profile?
A profile is where Formetrix stores and evaluates:
-
Measurement history
-
Composition estimates and interpretation indexes
-
Visual documentation (Body Studio)
-
Trends, summaries, and insights
-
Sharing and access permissions
Each profile maintains its own independent timeline. Data from one profile never mixes with another.
This makes profiles suitable for different use cases without compromising clarity or privacy.
Why Multiple Profiles Exist
Depending on your plan, you can create multiple profiles within your account.
Profiles are useful when you want to:
-
Separate personal tracking from professional or experimental tracking
-
Maintain independent histories for different goals or time periods
-
Share specific data with others without exposing everything
Each profile remains isolated, even when managed from the same account.
Sharing and Permissions
Profiles can be shared explicitly with others, such as:
-
Coaches
-
Clinicians
-
Trainers
-
Collaborators
Sharing is permission-based. You decide:
-
Which profile is shared
-
What level of access is granted
-
When access can be revoked
Shared access does not transfer ownership. The profile and its data always remain under your control.
Measurement History and Continuity
In Formetrix, every measurement is a snapshot.
When you record measurements, you are capturing the state of your body at a specific moment in time in an ongoing process. On its own, that snapshot is useful, but incomplete.
Real understanding comes from how snapshots relate to one another.
This is why Formetrix is built around profiles and history.
Cumulative View vs. Single Measurements
In Formetrix, you can view your data in two complementary ways:
-
Individual measurements
A single snapshot at a specific time (tₙ). It shows exactly what was recorded in that session.
-
Cumulative view
A complete “current state” view built from your timeline.
The cumulative view works like this: Formetrix sorts your measurements in ascending time order and builds an effective snapshot by taking, for each field, the latest non-empty value available up to that point. In other words, if a measurement wasn’t entered in a session (left blank), Formetrix carries forward the most recent value you previously recorded.
This allows Formetrix to present the most complete model possible at each point in time — without forcing you to re-enter values that rarely change.
Why it matters
The cumulative view helps you:
-
Enter less, track more: only update what changed, instead of retyping everything every time
-
Keep a complete model: see a full, consistent overview even when you don’t measure every field on every session
-
Calculate more indexes reliably: more fields remain available to compute composition metrics and interpretation indexes
-
Speed up logging: reduce friction and make measurement sessions practical to maintain long-term
Note
The Cumulative View does not overwrite your history. It is a reconstructed view designed for convenience and completeness. Refer to Cumulative Model for more details.
Creating a Profile
When creating a profile, you are asked to enter a set of profile details. Some fields are required, while others are optional.
-
Required fields establish the minimum context needed for accurate calculations.
-
Optional fields improve interpretation quality and long-term insight.
The more complete the profile information, the more contextual understanding Formetrix can provide — especially for interpretation indexes and AI-assisted insights.
Privacy & ToS
Privacy details and data handling are documented separately at https://formetrix.fit/Privacy
Profile Gender and Age (Important)
Both the gender & age fields are locked once a profile is created and cannot be changed later.
This is intentional. Age & Gender are core dependencies for:
-
Composition estimation formulas
-
Interpretation index ranges
-
Long-term trend normalization
-
AI-assisted interpretation logic
Changing either after measurements exist would invalidate historical comparisons and derived insights. Locking this field ensures data consistency and interpretability over time.
If tracking under a different context is needed, a new profile should be created.
