Free fitness calculators + a plan that adapts to you

RizzFit turns one-off fitness numbers into a plan that learns. Start with 18 free calculators (TDEE, macros, protein, body fat, 1RM, calorie deficit, heart-rate zones) that show their formulas and sources, with no signup. Then let the app adjust your calories and training from your real progress trend.

Hi Product Hunt! I'm Aathi, a solo dev from Toronto. I built RizzFit because every calculator I used gave me a different number, and none of them updated when reality disagreed. Every RizzFit calculator shows its formula and source, and the app recalibrates your targets from your actual weight and performance trend. Tell me which calculator you'd want next!
