Interactive tools — real data, free.
We built the tools that actually answer the questions repeat dieters keep asking — TDEE that accounts for metabolic adaptation, an insulin-resistance proxy that works without a blood draw, a UPF audit that reads your day's eating in plain English, and a 12-week off-ramp planner for adults coming off GLP-1s. No account required.
