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.
Free online eye tests for quick vision screening
EyeTest Online is a free browser-based collection of vision screening tools designed to make basic eye checks easier to access from home. The website includes tests for visual acuity, color blindness, astigmatism, contrast sensitivity, central vision, peripheral vision, near vision, Amsler grid screening, and other common eye checks. Each test runs directly in a modern web browser, so users do not need to create an account, download software, or install an application before getting started. One of the main goals of EyeTest Online is simplicity. Users can open the website, choose the type of vision test they want to try, follow the on-screen instructions, and begin screening within minutes. The tools are designed to work across desktop computers, laptops, tablets, and mobile devices. The project also focuses on making browser-based vision testing easier to understand. Screen size, viewing distance, brightness, lighting conditions, and device calibration can all influence the result of an online eye test, so the website provides instructions to help users complete each screening as consistently as possible. EyeTest Online is intended for personal vision screening and general eye-health awareness. It does not provide medical diagnosis and should not be used as a replacement for a comprehensive eye examination performed by an optometrist or ophthalmologist. The service is free to use and is designed for anyone looking for a simple way to perform basic vision checks online without registration or installation.
