A well thought out tracker

A clean, simple, and intuitive interface that’s really helped me stay on top of my health and eating habits. I highly recommend it!

Response from developer

Appreciate the kind words! Keeping the screens clean and uncluttered took a lot of work, so thank you for noticing.

It’s here at last!

This app is great! As I enter my early 60s, I’m focusing on my health more than ever. I’ve always been careful about my diet and taken care of my health, but life changes, and so does our metabolism. As we get older, it becomes even more important to pay attention to our nutritional needs and make the right choices for our future.

Trio has given me a new perspective on nutrition and how to prepare for a healthier life as I age. The app is simple, informative, and easy to use, with practical guidance that makes healthy eating feel achievable.

I especially appreciate its focus on bone health, which is so important as we get older. Trio helps keep me on track and motivates me to make better choices every day.

I love how simple, practical, and user-friendly this app is! If you want to improve your eating habits, support your bone health, and build a healthier lifestyle for the years ahead, I definitely recommend Trio!

A must if you were diagnosed with osteoporosis

This app showed me how to easily reach my doctor’s recommended daily calcium from food. I completely ditched the supplements! I’m saving money and eating healthier.
