Today's number varies.
The trend doesn't lie.
Your weight varies every day — water, a meal, your cycle. What matters is the average over time, not this morning's figure. 30 days of history on weight alone, free, with no time limit. The rest — food, activity, reminders, and the Partner, the support that never shows your weight to anyone — is Premium, with one month free.

Léa, your partner, sees this:
Trend going up · 3 weigh-ins this weekSupport, without exposure
Never the figure — your partner sees a direction (📉 ➡️ 📈) and your regularity, never your weight in kilos.
A mutual link — the person you make your partner can, in return, make you theirs.
You choose what is shared — direction, regularity, meals, activity: each category switches on or off separately.
Encouragement, not messages — a handful of ready-made lines, never free text.

Weight, free, with 30 days of history. Everything else, in a single Premium plan.

Frequently asked questions
Can I install it on my phone?
Yes: Objectif Poids installs like an app from the browser — on Android, Chrome offers "Install app"; on iPhone, Safari → Share button → "Add to Home Screen". Its Google Play and App Store releases are in preparation.
Why is only weight free?
To stay honest about what we give away: 30 days of history to judge whether the trend curve speaks to you, with nothing else half-tried. The rest — food, activity, the Partner — forms a coherent whole we'd rather offer entirely, or not at all.
What happens after the 30 days of history?
Nothing stops and nothing is deleted. You keep weighing in as long as you like; only weigh-ins older than 30 days stop being visible without Premium. They come back in full as soon as you subscribe.
How long is the Premium trial?
1 month, free when you subscribe (card required, nothing charged if you cancel before the end). A month to try food, activity and the Partner in real conditions.
What is the Partner?
The person you invite to support you. They see a trend direction and your regularity — never your weight in kilos. The link is mutual, and sharing is set category by category.
What is « your noise »?
The gap between the day's weigh-in and the trend is what daily life makes vary — water, last night's meal, your cycle. Measured on your own weigh-ins, that usual gap becomes a range (±0.6 kg for one person, ±1.2 kg for another). Each weigh-in is then placed inside that range, and the day's number stops being a verdict. It's free: it's the whole point of the product.
How is the trend calculated?
It's the average of your weigh-ins over the last 7 days, that day included. Nothing more: no opaque smoothing, no hidden weighting. You could recompute the displayed value by hand, with a calculator.
Do I have to count calories?
No. The meal journal records a qualitative marker (light, balanced, hearty), to spot patterns. A free numeric field exists for those who want it, off by default — with no daily target, no food database, and never for activity.
Is Objectif Poids a medical device?
No. It's a personal tracking journal, not medical advice. For any health question, a professional remains the right person to ask.
30 days of history, free
An account, a first weigh-in, a goal if you want one. The trend does the rest.
