Forecasts that must earn the label
A next-day energy forecast is called 'validated' only if, on your own past days, it beats simply guessing your usual energy. Otherwise it's clearly marked illustrative.
Personal biometric digital twin
A twin that knows your normal — and shows its work.
LifeTwin AI learns personal baselines from your sleep, movement, heart and mood. It tests its own forecasts against your history, and every insight comes with the evidence behind it.

Guide
From first login to a trustworthy twin
- 1
Create your account and choose consent
Storage consent is required. AI explanations are a separate, optional switch you can turn off any time.
- 2
Add your data
Log a daily check-in or import a CSV/JSON export. Apple Health and Health Connect will sync through the mobile apps once they're released.
- 3
Give it 7 days, ideally 28
Baselines appear after 7 valid days and gain confidence at 14+. Forecasts and relationships need enough paired days to be tested.

Read the explanations, keep the caveats
Every insight shows its observation count, period and limitations. Associations are never presented as causes.
What makes it extra
Most wellness apps give you scores. LifeTwin gives you the evidence behind them.
AI that's fact-checked before you see it
AI answers are checked against the evidence. An invented number, a measurement it wasn't given, or diagnosis-style language gets the answer replaced with a standard explanation.
Measured, derived and predicted, kept apart
Your raw measurements, the statistics computed from them, and predictions are stored and labeled separately, so you always know which one you're looking at.
Consent per source and per category
Choose exactly which categories each source may store. Turning a source off stops new data immediately, and you can delete what it already sent.
A research console that grades itself
Backtests, forecast error, calibration and comparisons with simple methods are all visible. Synthetic benchmarks are labeled and never presented as medical accuracy.
Meet the version of you that's made of evidence.
LifeTwin AI is a wellness tool, not a medical device. It doesn't diagnose, and it tells you when it doesn't have enough data.
