About this app

Better Weight is a free weight tracker and BMI calculator that helps you lose weight, gain weight, or reach your ideal weight. Monitor your BMI, track progress, and see real results — all in one simple app.

Whether your goal is to slim down or build up, splitting it into smaller milestones is a smart plan. Set your target, track daily or weekly, and stay motivated. Small wins keep you happy and moving forward.


📊 WEIGHT TRACKER & BMI CALCULATOR

Our weight tracker makes it easy to log every weigh-in. See your progress on daily, weekly, or monthly charts. Because numbers fluctuate, we show a 7-day low and meaningful trends instead of confusing daily readings.

The built-in BMI calculator lets you calculate your body mass index instantly. Know where you stand — underweight, normal, overweight, or obese — and track how your BMI improves over time.


📏 BODY MEASUREMENTS & BODY FAT

Numbers on the scale don't tell the full story. Track body measurements like waist, hips, chest, and arms to see what's really changing. Calculate your body fat percentage and get the bigger picture beyond a single number.

Want to go beyond the numbers? Body Scan gives you a personalized breakdown of your posture, muscle tone and body composition — just from photos.


🎯 GOALS, PLANS & CHALLENGES

Set your weight loss goal and create a step-by-step plan to reach it. Pick from curated 28-day challenges — healthy habits like daily exercise, stretching, drinking water, or eating right. Choose the difficulty and build a routine that fits your life.


⚖️ SIMPLE & BEAUTIFUL WEIGH-INS

Logging is designed to be beautiful and simple. Step on your scale, log your number, and move on. Quick weigh-ins make it easy to build a daily habit. Use your weight log as a personal weight diary to look back on your journey anytime.

Very positive. It is easy to use, got a great deal on pro, and has everything that I like to keep track of. Others may want more but I am happy with it so far. 10/10

Premium user here. This is good as a basic weight entry app. My biggest problem is a missing Import feature, when moving to this app from another. Add to this a lack of connectivity with Health Connect, and you are effectively locking away any data you enter here, with no way of retrieving it later. I see multiple requests here to enable Health Connect sync, please pick this up on priority.

Thank you for the thoughtful feedback and for being a Premium user! Data import and Health Connect integration are both great suggestions — we've noted them for the team. If you'd like to export your current data or share more details, feel free to reach out at [email protected]. We appreciate you!

Thank you for the five stars, this made our day. Better Weight keeps your data on your device by design, so it's always there when you need it. 💚

What’s new

You can now log your GLP-1 alongside your weigh-ins. We've added tracking so you can see how your medication fits into the longer trend, right on the same chart.
