About
SlimOrNo, your simple, complete and kind weight-loss companion.
5 tools to better understand your relationship with weight, without dieting or frustration.
THE 6-QUESTION CHECK-IN
A mini quiz that sheds light on your relationship with food: snacking, speed at the table, hidden sugars, portions, activity, emotion management. No judgment, just an honest look.
MY BMI
Enter your weight and height — the BMI is calculated. SlimOrNo places it (underweight, normal, overweight…) and tells you the target weight to get back in range.
WEIGHT TRACKING
Weigh in whenever you want, log the number. SlimOrNo draws a simple curve and keeps the history. You see where you stand at a glance.
TIP OF THE DAY
30 tips inspired by the book "Oui Vous Allez Maigrir". One a day, all viewable. Mark your favorites.
LOGBOOK
Each day, in a few words, note what you ate, your mood, your activity. All your notes stay on your iPhone.
PRIVACY
SlimOrNo collects no data. No account. No ads. No internet connection (except if you open the link to the book).
TO GO FURTHER
SlimOrNo is inspired by the book "Oui Vous Allez Maigrir" by Alain Ranvier, available on Amazon — a gentle, frustration-free approach to understanding and lightening sustainably.
