Health & Lifestyle

A lot of health questions start with a number: What’s my BMI? How many calories should I eat? When should I go to bed if I want to wake up between sleep cycles? The calculators here don’t replace a doctor or a nutritionist—they give you a starting point. You enter your details, get a result in seconds, and use it as a rough guide. All of it runs on your device; we don’t collect or store any of your health data.

You’ll find tools for BMI and ideal weight range, BMR and daily calorie needs, water intake, sleep timing, and more. Parents use the age calculator for forms; people watching their weight use BMI and calories to set targets. The sleep calculator is for anyone who’s tried to wake up in the middle of a deep cycle and felt like a zombie. Again: these are for general awareness, not diagnosis or treatment.

We built these tools so the maths happens on your device—we don’t receive or store your height, weight, or other details. If you’re curious about your numbers or want a quick check before a check-up, the tools below are there. For anything that affects your health decisions, talk to a healthcare provider; for a fast, private look at the basics, you’re in the right place.
