Unexplained weight gain. Cravings that hijack your week. Plateaus that make no sense.
It might not be your willpower — it might be your hormones
Hormones can influence weight, cravings, and energy — but most women never get to see their own. Mira's at-home tracker lets you, and our beta is the first way in.

If any of this sounds familiar, you're in the right place.
These are the stories we hear most often from women struggling with weight:
"I count calories, hit my workouts, track my sleep — and the results still don't add up."
"As I moved through peri/menopause, weight gain gradually crept in. I'm doing the same things I always did, but nothing seems to work anymore."
"I've lost the same 10 pounds five times. It works — until it doesn't."
"I'm on GLP-1 medication. It's changing my weight — but I have no idea what it's doing to my hormones, or what's behind the side effects I'm feeling."
Weight loss works differently for women.
Your hormones could be the missing piece

Inside the beta: a weight management program that turns your hormone insights into daily actions
Here's what you'll experience as a beta tester
1
Hormone testing, made simple
Dip a wand, insert it into the Mira Monitor — done. One test reads 4 hormones, and the app tells you exactly when to test and why.
2
See what your body is actually doing
Real hormone values in plain language, charted alongside your weight trends. So when the scale stalls, you have more context about what may be happening in your body
3
Follow a program built around your cycle
Daily actions matched to your hormonal phase — which nutrients to prioritize, how to move, when to push and when to rest. Cycle goals and milestone reports show your progress even in weeks when the scale doesn't move.
4
Log what matters, skip the busywork
Weight, meals, symptoms, cravings — logged in seconds, helping you uncover patterns over time.
5
Connect actions to outcomes
See your hormone patterns, habits, symptoms, and weight trends in one place. Track changes over time and explore how they relate to your progress. Create shareable progress reports to track the impact of your actions over time.
This is what beta testers will get first — and what your feedback will help shape
