Spanlet estimates your lifespan by starting from average life expectancy for your country and sex, adjusting it for your current age, then adding or subtracting conservative amounts for each habit. The result never drops below your current age plus one year. It is an estimate for motivation, not a medical prediction.

FAQ
- Do I have to pay to see my result?
- No. Spanlet shows your estimated lifespan as soon as you finish the quiz. There is no paywall and no subscription; the app is supported by ads, and no full-screen ad appears before your first result.
- Can I go back and fix an answer?
- Yes. You can go back or skip any question, and your progress is saved after every answer. Later you can change any habit from the home screen without retaking the quiz.
- Why did my number barely change when I changed an answer?
- Each habit moves the estimate by a conservative, capped amount shown in years next to it. Big levers such as smoking move it a lot; small ones such as stress move it a little.
- Can it say I have already died?
- No. The estimate is adjusted for your current age and never drops below your current age plus one year.
- Does it count health conditions like diabetes or high blood pressure?
- Yes. The quiz asks about diabetes, high blood pressure and heart disease, plus family history, and each one changes the estimate.
- Is there a home screen widget?
- Yes. The widget shows your days left and today's check-ins, free.
- Is this medical advice?
- No. Spanlet's numbers are estimates for motivation and entertainment only. Talk to a doctor about your health.
- What data does Spanlet collect?
- There is no account. Your answers and check-ins stay on your phone. Ads are served by Google AdMob; see the privacy policy for details.
