How It Works

I Built a System to Detect What's Quietly Breaking

I am a senior leader at a global healthcare company. I built Free60 because I had data everywhere and no system that could tell me what was actually degrading. Sleep tracker said fine. Income was stable. Calendar was full. But recovery was not matching load, expenses were creeping, and my time allocation had drifted from my priorities. No single tool could see the cross-dimensional picture.

What was the actual problem?

I had an Apple Watch tracking sleep and activity. A spreadsheet tracking finances. A calendar full of meetings. Separate apps for each domain, each producing its own data. None of them talked to each other, and none of them could answer the question I actually cared about: is my system stable, or is something quietly failing?

The answer was not in any single data source. My sleep duration was 7+ hours, which looked fine. But my HRV was declining over weeks, which meant my autonomic system was accumulating load faster than it could recover. My income was stable, but my expense-to-income ratio had crept up 4 percentage points over six months. My calendar was full, but the ratio of strategic work to reactive meetings had shifted. Each domain had a subtle drift that no individual tool flagged.

I looked for something that measured structural stability across domains. Health apps measured health. Finance apps measured finances. Productivity apps measured tasks. Nothing measured the system. So I built one.

What does the system actually measure?

Free60 is a life diagnostic. It measures structural stability across 3 dimensions: Health, Wealth, and Capacity. There are 15 levers and 26 KPIs total. Every KPI produces a score. Scores aggregate up through levers and dimensions into a single number: the Freedom Index, scored 0 to 360 (scaled when you activate fewer than three dimensions).

The number is not a grade. It is a diagnostic reading, like a gauge cluster in a car. Each gauge has a range. Green means stable. Yellow means drifting. Red means structural failure is likely if the trend continues. But the system goes further than a gauge. Automated insight cards explain why each failure matters, show cascading effects across systems, and surface specific actions based on your data.

Every metric was selected against strict criteria: it must detect a real problem, require minimal effort to track, have meaningful consequences if it fails, surface quickly, and measure structural conditions rather than behavioral compliance. This is how 26 KPIs were selected from hundreds of candidates.

How does the data flow in?

Health data comes from Apple Health (iOS) and Health Connect (Android). Free60 reads heart rate, HRV, sleep sessions, step count, exercise minutes, and resting heart rate passively from your wearable when present. Seven automated KPIs across Sleep, Activity, and Load calculate from this data. Nutrition and Care add structured periodic input inside the same dimension.

Wealth data is entered in the Free60 app: income, expenses, liquidity, investments, and risk, with broker linking and fast expense capture where you enable them. Optional Wealth Tracker sheets still exist for spreadsheet-first users. Updates are change-driven or on your review cadence, not a daily ledger.

Capacity combines calendar reads (schedule shape, buffer gaps, some boundary checks) with short in-app modules for priorities, focus, and routine. The friction model matches Health and Wealth: automate what can be automated, keep manual slices small and surfaced through Quick Actions.

What is the technical architecture?

Free60 is available on iOS and Android. Health data stays on your device via Apple Health or Health Connect. Wealth structures live in-app under your account; optional sheets are yours if you use them. AI analysis runs on your scores, not your raw biometric stream. No data is sold. No ads.

What is the Freedom Index?

The Freedom Index is a single number from 0 to 360 that aggregates all 26 KPIs. The math works bottom-up: each KPI scores 0 to 100. KPI scores aggregate into lever scores (weighted by systemic importance). Lever scores aggregate into dimension scores. The three dimension scores combine into the Freedom Index.

360 is the maximum when all three dimensions are active: each dimension contributes up to 120 points (3 x 120 = 360). If you activate fewer dimensions, the maximum scales down so partial adoption is not penalized. A person with strong Health but failing Wealth still sees Wealth drag the Freedom Index. The system measures the whole configuration you turned on, not an arbitrary subset.

What design constraints shaped it?

Several constraints were non-negotiable from the start:

• No prescriptions. Free60 detects. It does not advise. Telling someone to "sleep more" or "spend less" is useless without their context. The system flags the structural failure. The human decides the response.
• No data transmission for biometrics. Health data stays on the device. This is not a privacy policy. It is an architecture decision. There is no server endpoint that accepts biometric data because the endpoint does not exist.
• No gamification. No streaks, no badges, no leaderboards. The target user is an analytical professional who finds gamification patronizing. The interface is structured around insight, not motivation.
• Minimal friction. If a KPI requires daily manual input, it fails the 5-gate framework. Automated where possible (Apple Health / Health Connect, calendar, integrations), low-frequency where manual, with Quick Actions surfacing only what is stale.
• Independent failure detection. Each KPI must detect a failure mode that no other KPI detects. Redundant measurements were eliminated during design. 26 KPIs remain because each one covers a unique structural risk.

Who is this for?

Free60 is for people who think in systems. Professionals who already collect data but lack a framework to diagnose what the data means structurally. People who are performing well on paper but suspect something is degrading underneath. People who want detection, not motivation.

It is available on iOS and Android, launching June 17, 2026. 7-day free trial, then $12.99/month or $99/year. It requires a smartphone and, for the Health dimension, a wearable device.

I built it because I needed it. I am shipping it because the problem is not unique to me.
