Feel younger, step by step!
Feel younger, step by step.
fjt tracks your health and biological age using nothing but your iPhone. No wearable, no ring, no chest strap. Just log your daily habits, meals and activities — fjt does the rest.
HOW OLD DO YOU REALLY FEEL?
Your birthday tells you one number. Your body tells another. fjt calculates your felt age from your daily check-ins, activity and wellbeing — and shows you how much younger you could feel.
SMALL STEPS, BIG DIFFERENCE
No 90-minute workouts, no extreme diets. fjt gives you one small thing to do each day. Do it, log it, watch your felt age drop.
WHAT YOU GET
- 60-second daily check-in based on the WHO-5 Wellbeing Index
- Biological age estimate built on the NTNU HUNT VO2max research
- Photo meal tracking — snap your plate, fjt logs it
- Activity logging with Apple Health sync
- AI recommendations tailored to your day
- Progress view showing your felt age week by week
BUILT FOR PRIVACY
Your health data belongs to you. Stored on EU servers, GDPR-compliant, never sold, never used for ads.
Start today. Feel younger tomorrow. One step at a time.
