UnityLife Tools
Free lifestyle calculators for Canadians.
Quick, ad-free tools we built because the internet’s existing ones are covered in pop-ups, paywalls and bad maths. All four are mobile-friendly, require no sign-up and work offline after the page loads.
Nutrition
TDEE Calculator
Estimate your Total Daily Energy Expenditure — the kcal you burn in a typical day — with the Mifflin–St Jeor equation.
Open the toolReference number
BMI Calculator
See your weight-to-height-squared ratio. We show the number only — no labels, no categories, no health verdict. Your doctor interprets it, not us.
Open the toolWork & productivity
Hours Calculator
Add up hours between two times — minus your break — with optional Canadian-dollar pay estimation. Handles overnight shifts.
Open the toolHydration
Water Intake Calculator
Rough daily water estimate based on body weight and activity level. A lifestyle starting point, not a prescription.
Open the toolWhy a tools page?
A TDEE estimate, a BMI number or a water-intake guess isn’t a diagnosis — it’s a starting point for your own curiosity. We built these tools because most online calculators are either cluttered with pop-ups, paywalled, or don’t work properly on a phone. Ours are free, fast, and framed for Canadians: pay in CAD, metric by default, no sign-up.
Every calculation is done client-side in your browser. Nothing you type is sent to our servers or saved anywhere. Each tool has an explainer below the fold with how it’s calculated and what it does and does not measure.
