Lose Weight You Can Actually Keep Off
Hi everyone 👋,
Over the past year I've been building Calqulate, and it started from a simple frustration.
Almost every health calculator online works the same way:
Enter your information.
Get one number.
Close the tab.
Whether it's BMI, body fat, GLP-1 dosing, or ideal body weight, most tools answer a single question but don't help with what comes next.
As GLP-1 medications like Ozempic, Wegovy, Mounjaro, and Zepbound became more common, I noticed another gap. People weren't just asking, "What's my dose?" They wanted answers to questions like:
Am I losing fat or muscle?
Is my medication still active today?
Why am I hungrier before my next injection?
Am I heading toward a plateau?
How much protein and water should I actually be getting?
Those aren't one-time questions—they're part of an ongoing journey.
So instead of building another calculator website, I'm building Calqulate Vitals, an AI-powered health companion.
The idea is simple:
Free calculators help people get started.
A free account lets them save progress and track their journey.
Premium adds forecasts, body composition insights, progress predictions, and long-term health tracking.
Some of the tools we're building include:
GLP-1 Dose Calculator
Drug Activity (Half-Life) Calculator
Injection Planner
Fat vs. Muscle Loss Tracker
Plateau Predictor
GLP-1 Progress Tracker
One feature I'm particularly excited about is showing fat loss vs. muscle loss, because the scale alone doesn't tell the whole story. Two people can lose the same amount of weight but have very different health outcomes.
We're still early, and there's plenty to improve. Right now I'm focused on making each calculator genuinely useful on its own while naturally leading into long-term tracking for users who want it.
I'd love feedback from other founders:
If you landed on a free health calculator from Google, what would convince you to create a free account instead of just leaving after getting your result?

Thank you! I completely agree.
That's exactly the shift I'm trying to make, from giving a number to helping people make better decisions over time. Saving a result alone isn't enough, but understanding what today's result means for tomorrow is where I believe the real value is.
Still validating that, so I really appreciate your feedback.
I like the shift from calculators to an ongoing health journey. One thing I'd keep validating is what earns the account creation. Saving a number rarely does—but helping users understand how today's result changes tomorrow's decisions often does.
