Your body gives you signals. Bion makes them useful.
Know what's working for your body.
Bion brings your health data into one clear view, scores the goal you care about, and shows you the next move worth making.

Your goal, your Score, your next move.
Start with your goal
Measure the change you actually care about.
A single health number cannot mean the same thing for everyone. Bion names the Score for your goal, then follows the outcomes that belong to it.
Lose fat and preserve muscle
On a GLP-1 or changing your routine another way, it checks your muscle, not just the scale, so you can see whether the weight coming off is the kind you want to lose.
Build muscle
Follow strength, body weight, and measurements together so you can see what your plan is really producing.
Maintain what you have earned
Keep an eye on the signals that matter while your routine, recovery, or treatment changes.


Connect once. Log only what helps.
Your wearable, scale, workouts, food, measurements, and medication can finally tell one story. Everything in one place, instead of scattered across separate apps.
- Connect
- Apple Health or Health Connect brings in the data you already collect.
- Fill the gaps
- Add a quick check-in, measurement, meal, workout, or dose when it helps.
- Keep control
- Start with what you have. More data can sharpen the picture, but expensive equipment is not required.
See the result. Understand why. Make the next move.
Your Score compares your progress with your own starting point. Tap it to see what is helping, what is steady, and what deserves your attention next.
You do the work. Your crew helps you keep going.
Share the right progress with the people you choose. A friend, coach, programme, or care team can check in, answer questions, and help you follow through.
You decide what to share. Your personal health data stays personal unless you choose otherwise.
