Overview
Common Ninja's TDEE Calculator widget lets visitors estimate their total daily energy expenditure, the number of calories they burn in a day, from details such as age, height, weight and activity level.
What it does
- Interactive calculator form on your page
- Instant result once the visitor enters their details
- Labels, colours and layout set in Common Ninja's editor
- Embeds with a code block
Who it suits
Personal trainers, gyms, nutrition coaches and fitness bloggers who want a useful tool that keeps visitors on the site and leads into a consultation or programme.
Honest caveats
Results are estimates, so pair it with a short note that it is not medical advice. The free plan has usage limits and paid plans are billed yearly per widget, from $24 a year. JavaScript in code blocks needs a Squarespace Core plan or higher. See our fitness templates guide.
Most teams evaluate it against manual layout tweaks: the pitch is faster iteration on interface components inside Squarespace pages without exporting the problem to custom code.
Fit depends on your template and commerce setup; compare Common Ninja’s live examples to your own navigation, commerce, or section patterns before buying.
Use SquareLocator as a starting point, then validate details (refunds, updates, support channels) directly with Common Ninja before committing.
Strongest when your brief explicitly mentions interface components inside Squarespace pages; weaker if you only need generic “make the site better” tooling.
