Get your daily carb target from your goal weight. Build blood-sugar-care habits — no needles required. Understanding blood sugar has traditionally meant wearing a sensor on your arm. Glucose Challenge helps you build lasting habits through your daily meals and actions — no sensor needed. ■ Start with your goal weight Enter your current and goal weight, and we'll suggest a daily carb target that fits you (Gentle 130g / Recommended 100g / Strict 70g). If you have a larger gap to close, we suggest starting with a sustainable target and stepping down after a month. Strict limits mean nothing if you can't keep them up. That target becomes the goal line on your daily graph — so you always know how much you have left today. ■ Built on data from 300+ participants Since 2020, over 300 people have worn a medical glucose sensor (FreeStyle Libre) while logging their meals and daily actions. That data shows, in numbers, which habits raise blood sugar and which ones help prevent spikes. A healthcare professional reviews that data and turns it into the actions you should take today. ■ Blood sugar isn't only about food Sleep, exercise, stress — all of it affects your blood sugar. So the habits you receive go beyond what's on your plate. ■ Two things to do each day 【1. Photograph your meal】 One photo is all it takes. AI estimates the carbs — no typing, no calculating. Every entry stacks up on your graph, so you can see at a glance whether you've passed your target. 【2. Check off today's actions】 "Vegetables first." "A short walk after eating." Habits arrive each day. Just tap whether you did it or not. ■ These two become your scores Your logged carbs and your habit completion rate feed into your Glycation Score and Spike Score. Your estimated HbA1c and 5-year diabetes risk appear on the dashboard too. No needles — and you can still see where you stand, in numbers. That's what 300+ participants' real data makes possible. ■ The longer you go, the further you get Your avatar evolves from Lv1 to Lv3 as your completion rate rises, and each level unlocks the next stage of habits. You start where you are, and build from there. ■ No more wondering what to eat Pick your goal (clear skin, weight care, anti-aging, wellness, diabetes prevention) and your situation (weekday lunch, dinner), and you'll get specific options for convenience stores, dining out, and home cooking. Repeat it daily, and eventually you'll choose well without opening the app. That's the goal of this program. ■ Also included ・Daily and weekly weight graphs with a goal line ・Carb breakdown per meal, plus advice to help prevent spikes 【Who this is for】 ・You spend on skincare, but your skin still isn't where you want it ・You've tried diets before and gained it back ・Your blood sugar or HbA1c came up at your last checkup ・You're busy, and detailed logging or calorie counting never sticks 【Subscription plans】 A 3-day free trial gives you access to everything. ・Basic (¥1,100/mo): Unlimited AI photo analysis, daily habits,  dashboard ・Standard (¥1,650/mo): Basic plus meal programs for weight care,  beauty, anti-aging, and wellness ・Premium (¥2,200/mo): Everything, including the healthcare-  supervised diabetes-prevention program and 5-year risk insights *Results vary by individual. No outcome is guaranteed. 【Medical disclaimer】 Estimated HbA1c, diabetes risk scores, and AI meal analysis in this app are simulations based on the data you enter. This app is not a medical device and does not provide medical diagnosis or definitive test results. For accurate measurement or any health concerns, please consult a physician.
