The algorithm builds on clinical trial data from thousands of users’ fitness trackers, CGMs, and food logs. “We wanted to come up with an easy and affordable way for everyone to have access to their blood sugar,” says CEO Noosheen Hashemi. _\*Disclosure: TIME owner and co-chair Marc Benioff is an investor in January AI_ These are independent reviews of the products mentioned, but TIME receives a commission when purchases are made through affiliate links at no additional cost to the purchaser. ```json [{"@context":"https://schema.org","@type":"Article","@id":"https://time.com/collections/best-inventions-2025/7318362/january-ai/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/collections/best-inventions-2025/7318362/january-ai/"},"headline":"January AI","datePublished":"2025-10-09T11:00:17.000Z","dateModified":"2026-04-13T11:54:52.210Z","description":"","url":"https://time.com/collections/best-inventions-2025/7318362/january-ai/","keywords":["Tech","E-Commerce","list","franchise","Magazine","best inventions","Special Project","sponsorshipblock","Accolades","Best Inventions 2025"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blta805073c83c9a59b/6998ca709fbc7c4d00d9a7cb/predictive-glucose-monitoring-TIME-best-inventions-2025.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Charlotte Hu","jobTitle":"Associate Editor","url":"https://time.com/author/charlotte-hu/"}],"creator":"Charlotte Hu","articleSection":"Business","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blta805073c83c9a59b/6998ca709fbc7c4d00d9a7cb/predictive-glucose-monitoring-TIME-best-inventions-2025.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/business/","name":"Business"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/time-section-tech/","name":"Tech"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/collections/best-inventions-2025/7318362/january-ai/","name":"January AI"}}]}] ```
