To really make progress and avoid playing like you're in a casino, it's important to have all the data right in front of you! That's exactly why we created our app!OneWin is a health calculator for people who want clear numbers about their body without signing up for anything. You enter your height, weight and age once.

🔢 BMI calculator
Move the two sliders and your BMI updates as you drag. A colored gauge shows the category (underweight, normal, overweight or obese), and the line under it gives the healthy weight range for your height 1win. You can work in kilograms and centimeters or in pounds, feet and inches.

🔥 Calorie calculator
Daily calorie needs come from the revised Harris-Benedict equation. Choose your sex, set weight, height and age, then pick one of five activity levels, from sedentary to athlete. Three numbers appear side by side: calories to lose weight (a 20% deficit), calories to maintain your weight, and calories to gain (a 15% surplus). The app remembers your choices, so the numbers are already filled in the next time you open it OneWin — BMI & Cal.

📉 Weight journal
Logging a weigh in takes two taps, and you can pick an earlier date incase you forgot a day. The chart shows your last 30 entries, each row in the list shows how much you gained or lost since the previous weigh-in. Set a goal weight and a progress bar tells you how far you have come and how many kilos or pounds are left. If you want a nudge everyday, turn on the weigh-in reminder and choose the time it rings. The reminder is scheduled on your phone, so it still arrives when you are offline OneWin — BMI & Cal.

🧰 Health tools
The tools screen collects four calculators that use the profile you already entered. Your weight follows your latest weigh-in 1win, and if your height or age changes you edit it once in Settings. Every tool updates on its own:

• Body fat percentage with the U.S. Navy method. You measure your neck and waist (and hips for women), and the app gives a percentage with a plain category such as athletic or average.
• Ideal weight from four classic formulas (Devine, Robinson, Miller and Hamwi), shown next to the healthy BMI range.
• A daily water target based on your weight and how many minutes you exercise.
• Daily grams of protein, carbs and fat, worked out for losing, keeping or gaining weight.

📋 History
Any BMI or calorie result can be saved with one tap. Saved results stay in a simple list with the date and the values you used, and you can delete any entry you no longer need.

🔒 Your data
Your health numbers stay on your phone, and every calculator works without an internet connection. Weight, height, measurements, weigh-ins and saved results are stored only on the device and are never uploaded. The app uses OneSignal to send optional tips and news. For that, OneSignal receives a device identifier, your language, your country and how often you open the app. It never receives your health data. You can switch notifications off in Settings, where the Delete my data button also erases everything in one step. There is no account to create, and the app has no ads and no in-app purchases - OneWin — BMI & Cal.
