Free tools
Small interactive tools that answer one question properly. No signup, no email, no paywall, nothing hidden behind a form. Each one shows its formula and links the primary source behind every coefficient — if we cannot cite a number, it does not ship.
Available now
- Chipotle Nutrition Calculator Official total plus the range you actually getNew
The only one of these calculators that shows two numbers. Chipotle’s own tool prices one standard scoop; Wells Fargo weighed 75 identical bowls across 8 NYC stores and found 14–27 oz. The realistic range applies that documented variance to the scooped items. Also totals sodium, which Chipotle’s calculator does not publish at all.
Open the tool → - CAVA Nutrition Calculator Build a CAVA bowl and watch calories and sodium add upNew
All 52 items from CAVA’s own March 2026 nutrition guide, with sodium totalled against the 2,300 mg daily value — which CAVA’s PDF cannot do. Items CAVA publishes no numbers for are shown as gaps, and the rows where its own printing contradicts itself are flagged rather than quietly fixed.
Open the tool → - Sweetgreen Nutrition Calculator The one chain that publishes a gram weight for everythingNew
All 80 items from Sweetgreen’s live ordering data, every ingredient with the gram weight Sweetgreen states — nothing converted or estimated. Enforces the same pick limits the real ordering system does, and explains why summing ingredients drifts from Sweetgreen’s own bowl totals.
Open the tool → - Water Intake Calculator Your daily drinking target in ounces or litres
Built on the National Academies Adequate Intake for your age and sex, minus the share that comes from food, plus fluid lost to training and heat. Shows the EFSA figure and the clinical per-kg rule side by side so you can see why every other calculator gives a different answer.

Listed so you know what is coming, not to pad the site. There are no empty pages behind these — they appear above once they actually work.
- Sweat Rate Calculator Measure how much fluid you actually lose per hourPlanned
Weigh in before and after a session and get your personal sweat rate, using the formula from the NATA fluid-replacement position statement. Feeds a far more accurate number into the water calculator than any intensity band can.
How these are built
- Sourced coefficients. Every constant traces to a named document — a reference body, a position statement, a peer-reviewed trial. Anything we estimate ourselves is labelled as an estimate in the interface.
- The math is visible. You get the breakdown, not just the answer, so you can check whether the assumptions fit you.
- Ranges over false precision. Where the underlying science gives a range, the tool gives a range.
- Nothing gated. No account, no email capture, no export paywall. Results share as a link or an image because that is useful, not because it farms contacts.
