SolviqLab: FREE health calculators, plus an optional AI coach for your next step

Hi makers — I’m building SolviqLab to help people connect a calculation with a clearer everyday decision.

A calculator can return a number quickly. The harder question is often: “What does this estimate actually answer, and what can I do next?”

Our FREE Health & Fitness collection includes BMI, calorie, TDEE, BMR, body fat and ideal weight calculators. Each tool starts with a different question; the results are not interchangeable.

For example, BMI describes weight relative to height. BMR estimates energy use at rest, while TDEE includes an activity estimate. If you’re exploring how activity affects daily energy needs, start with that question rather than interpreting BMI as a calorie target.

The next step is optional: Mia, our AI health coach, lets people explore their goals and possible next steps after using a calculator. The calculators are free; coaching is a separate service.

I’d love feedback on the handoff: after seeing a calculator result, would you prefer a clearer explanation, another relevant calculator, or an optional coaching conversation?
