At a glance
Track calories by adjusting meal ingredients and portions without AI
Calk is a calorie and nutrition tracker for people tired of searching huge food databases, trusting photo AI guesses, and logging every meal forever. Instead of rebuilding the same dishes each day, users choose familiar meal templates and adjust the ingredients, cooking method, extras, and portion. Calk then recalculates calories, macros, vitamins, and minerals using checked food data. The product is designed around focused logging with a clear endpoint. After a month of tracking, users receive a personal Nutrition Report that reveals recurring meals and nutrition patterns. They can then step back from daily food logging and follow their weight trend. If that trend changes, Calk helps them decide when another short food check may be useful. Calk is built for adults who want to lose, maintain, or better understand their weight without turning calorie counting into a permanent job. Core food logging, calorie and macro targets, weight entries, a weight-trend chart, and a seven-day Variety Map are free. The first 30 days include the first Nutrition Report and full insights. Continued reports and the expanded meal library are available with an annual subscription. Calk works on iPhone, iPad, and Android, supports offline logging, and contains no ads.
The smart ring that tracks sleep, readiness, and activity
Oura packs clinical-grade sensors into a titanium ring that scores your sleep, recovery, and daily readiness — the wearable that made health tracking invisible.
