Plan your retirement against your trajectory.

People spend roughly five hours a year planning for retirement — fewer than they spend researching a major appliance. The disproportion is not laziness. It is the symptom of a planning frame that has not earned the time, because it gives generic answers to the questions that matter most.

What you get on day one

Four things, in this order.

01

Connect step data

Install the app, indicate year and month of birth and sex, grant access to step data already on your device. No new hardware. No medical appointments.

02

See your indicators

Your biological age relative to chronological. Your aging speed, with its trend over the last 30 days. A baseline retirement projection alongside.

03

Adjust assumptions

Move your retirement date and watch the projection respond. Change contribution levels. Test what-ifs grounded in your actual trajectory.

04

Compare over time

Save reports. Watch trends emerge. Share — with explicit consent — with your financial advisor when you have one.

A worked example

Same person, two different aging speeds.

Two 52-year-olds with the same savings, contributions, and target retirement age. Their aging trajectories diverge. So do their plans.

Person A
aging speed −4.8 yrs
47.2 bio
52 chronological · slower than calendar
  • Horizon: longer than population average
  • Withdrawal: conservative — funds need to last
  • Allocation: stays in growth assets longer
  • Working life: may extend with confidence
Person B
aging speed +4.0 yrs
56.0 bio
52 chronological · faster than calendar
  • Horizon: shorter — bring decisions forward
  • Withdrawal: can support a higher initial rate
  • Allocation: may shift defensive sooner
  • Working life: consider an earlier, lower-stress exit

These reshapings aren't recommendations from the product. They're decisions you make — together with an advisor where relevant — once your inputs are personal rather than averaged.

Behaviour the signal changes

What people do with the reading.

A number you see once changes nothing. A number you revisit weekly, that moves with the choices behind it, changes what you do — both in how you live and how you plan.

Aging slower than the calendar
e.g. −4 yrs
  • ·Preserve the patterns — sleep, recovery, sustained movement — that built the signal
  • ·Light, periodic medical monitoring rather than reactive intervention
  • ·Plan for a payout horizon that may run longer than the population average
  • ·Bandwidth to consider career or lifestyle shifts you'd otherwise defer
Aging faster than the calendar
e.g. +4 yrs
  • ·Targeted clinical review — bloodwork, cardio, sleep — to find what the signal is reflecting
  • ·Bring decisions forward: financial moves and life choices while in good shape
  • ·Reassess work–life balance; reduce sustained stress where it shows in the trend
  • ·Plan a shorter, more concentrated retirement payout cadence

People want to live longer and healthier. A regularly-updated aging trajectory makes that intention measurable — week by week, in the patterns that move the signal, and decade by decade, in the retirement plan that depends on it.

What it doesn't do

Honesty is a feature.

Not a medical device. We do not store regulated medical signals like raw heart-rate or ECG data.

Not regulated financial advice. The product helps you think about decisions; it does not make them on your behalf.

Not a wearable replacement. Your phone's step data is enough — though wearables work too.
