Train it.
Eat it.
Measure it.
Four working sets, four meals, and body composition read straight off your scale. Every session opens with what you lifted last time.
The whole twelve-week plan, the shopping list and the Sunday prep sequence — one document, sent once. Or open the app free, no account needed.
Seven screens. Nothing you won't use.
No feed, no streak to protect, no badges. A log that tells you what to lift, what to eat, and whether it's working.
Logged between sets, not after
Plan on the left, actual on the right, four sets and out.
Four programmes, one structure
Every one is twelve weeks and uses the same four working sets, so you can switch without losing the thread. What changes is the split, the rep scheme and the calorie target.
Works with Withings
Connect your Withings account once. From then on, every time you step on the scale the reading is in Twelve within seconds — weight, body fat, fat mass, lean mass, muscle, bone, water, visceral fat, heart rate.
No typing, no forgetting, no rounding down to the number you were hoping for. The scale measured it; you didn't estimate it.

We are applying to sell Withings devices directly
Twelve already reads from any Withings scale you own. We have applied through the Withings Partner Hub to carry their devices ourselves, so you could buy the scale and the programme together and have it arrive already paired.
Until that is approved, the scales in our store are Twelve's own hardware. We do not use Withings product photography and we do not sell their devices yet. Buy directly from Withings →
Connect once
One authorization in the app. Tokens refresh themselves — the link doesn't quietly die three days later.
Pushed, not polled
Withings notifies us the moment you weigh in. Nothing to open, nothing to sync.
Every metric, kept
Measures we don't recognise are stored anyway, so a firmware update can't silently drop a number you care about.
The scale does the logging
Weight, body fat, lean mass, muscle, bone, water and visceral fat — read on the scale, in the app seconds later. Nothing typed, nothing forgotten, nothing rounded to the number you wanted.
These are Withings devices, and we don't sell them yet
Twelve reads from any of them the moment you connect your account. We have applied through the Withings Partner Hub to carry them ourselves; until that is approved, buy directly from Withings. We show no product photography here because the photographs are theirs, not ours.
Body composition from bioimpedance is directional, not clinical. The trend over twelve weeks is the number that matters. How it connects →
Everything we make
Single-ingredient where it matters. Every product shows its dose against the dose used in the research, and says plainly where the evidence is thin.
Questions about the program
Training structure, meal planning, how the app works. Anything medical — dosing, interactions, symptoms — goes to your pharmacist or doctor, and this will tell you so rather than guessing.
Twelve weeks from today is still twelve weeks.
The program works at twelve weeks. It doesn't work faster because you want it to, and it doesn't start until you log week one.
