Open source · Local first · Provider neutral
Your fitness history is more than a ZIP.
Turn the data you can download into a history you can search, understand, compare, annotate and carry with you—without handing it to another platform.

Your sports history · 2022–2026
Four ways you kept moving.
01 · WHY
Downloading your data is a right. Using it should be a reality.
A machine-readable archive satisfies access better than it satisfies understanding. FitFreed exists to make a portable history genuinely useful: transparent transformations, durable local storage, open formats and an application no provider can switch off.
GDPR-enabled portability + open-source software = meaningful user freedom
Training first. Evidence always.
Start with a question. Go as deep as the data allows.
Questions and recognizable sessions lead the experience. Metrics, health context and provider diagnostics support the answer instead of competing for the first viewport.
How has my training changed?
Compare periods while keeping active days, exact sessions, coverage and gaps visible.
Where is that session I remember?
Browse by sport, chronology, route and available measurements across the whole history.
What happened inside it?
Inspect structure, signals, route and exact values without mistaking a chart for evidence.
FROM SESSION TO EVIDENCE
The average is only the beginning.
Source laps, FitFreed-derived segments and your own criteria remain visibly different. When the provider recorded no useful phases, define equal time, equal distance, zones or manual boundaries without changing the imported record.
- Recorded facts keep their source and exact values.
- Missing measurements stay unavailable, never zero.
- Every visual has an accessible exact alternative.

Own the result, too.
Build a report, not a screenshot.
Begin from an answer or session, arrange evidence and exact values, add your own interpretation, save the definition and reopen it after the history changes.
- Compose recorded facts, calculations, coverage and your words.
- Review what a later import changes before refreshing.
- Export a self-contained result after checking sensitive content.
Freedom needs architecture.
Private by default. Inspectable by design. Portable by contract.
Local first
Core use works without a FitFreed account or mandatory hosted service.
Explainable
Source facts, mappings, calculations, gaps and unsupported content remain inspectable.
Portable again
Versioned open formats, backups and exports prevent replacement lock-in.
Open source
GPL-3.0-or-later code lets a community audit, repair and extend the product.
Ambitious, without pretending.
What exists, what comes next, and what can wait.
No roadmap capability is marketed as a released feature.
The trusted data spine
- Polar Flow ZIP validation and import
- Explicit supported, ignored, and unrecognized coverage
- Safe exact and cumulative reimport
- Provider-neutral SQLite history for activity, training summaries, sleep, and recovery
- Bounded visual comparison and longitudinal context
- First-run Sources home with offline export guidance and allowlisted official links
- Durable language, appearance, and content zoom settings
- en-US and es-ES, packaging, update recovery, and release-shaped tests
The experience being shaped
- Question-led home and post-import reveal
- Sports and full-history session discovery
- Routed and non-routed session evidence workspaces
- Origin-aware navigation across discovery, session, and report workspaces
- Saved evidence reports with self-contained HTML export
- A coherent, evaluated, documented macOS product journey
Expansion after value is proven
- Additional providers and live APIs
- Linux and Windows distribution
- Local MCP access for authorized agents
- Advanced encryption and extension systems
- Collaborative or hosted analytics
- Features without validated user value
The public macOS release still requires exact-candidate evaluation, production trust and explicit publication. See the readiness ledger.
A project without collaborators has an expiry date.
Help make personal fitness history genuinely free.
Import formats, domain modeling, accessible visualization, Rust, React, testing, documentation, translation and product design all have a durable home here.
“The record is yours.
The tools should be, too.
