What is LONGIST?
LONGIST is an AI-powered mobile application designed as 'The Biohacker’s Longevity Toolkit.' It is engineered for biohackers and longevity obsessives, aiming to help users gain up to 13 healthy years of life. The platform reimagines nutrition by shifting the focus from traditional calorie counting to quantifying how food choices impact one's lifespan. It provides science-backed insights into how each bite adds or subtracts minutes from a user's life, offering a detailed explanation of overconsumed and underconsumed nutrient groups and personalized guidance to optimize dietary choices for a longer, healthier life.
How to use LONGIST
Users begin by downloading the LONGIST app, available on the App Store and Google Play. The core interaction involves snapping a photo of a meal, a restaurant menu, or a barcode. The app then instantly analyzes the food, providing a breakdown of nutrient groups and showing how each ingredient impacts the user's lifespan in minutes. Users receive real-time guidance and can consult an AI Longevity Coach for optimized recommendations. The app integrates with Apple Health (HealthKit) to incorporate real-time metrics like steps, heart rate, and sleep for more personalized recommendations. LONGIST offers a Free Plan with core features, and premium features are available through Monthly ($9.99/month) or Annual ($59.99/year) subscription plans, which include unlimited meal logging, real-time longevity scoring, menu scanning, HealthKit sync, and AI Longevity Coach access.

FAQ from LONGIST
How does Longist calculate minutes added or lost from my life?
Longist uses real research from leading universities to estimate how different foods impact your healthy lifespan. Our AI identifies your meal and applies longevity scores based on peer-reviewed nutrition data—just snap a photo and get instant insights.
Is Longist science-backed?
Yes. Longist is built on the Health Nutritional Index from a Nature Food study and backed by data on over 5,800 foods. Every score you see is rooted in research and updated as new studies emerge.
What do the scores mean?
Each food is scored by how it affects your healthspan—adding or subtracting minutes of healthy life. A green score means it’s a longevity booster. A red or yellow score means it may shorten your healthspan if consumed often.
Does Longist track calories or macros?
Nope. Longist skips the complexity. Instead of calories or grams, we focus on what truly matters—how your food choices affect your longevity and organ systems like heart, brain, and gut health.
What if I eat mixed meals or restaurant dishes?
Longist is designed for real-life eating. Just snap a photo—our AI can identify multiple foods in a dish and analyze the combined impact. You can also scan menus to choose smarter meals on the go.
Is my health data private?
Absolutely. Longist does not store your HealthKit or food scan data on our servers. Everything stays private and secure on your device, with full transparency.
Can Longist help me lose weight?
Longist focuses on longevity, not weight loss—but many users naturally eat healthier and lose weight as a result. It helps you build sustainable habits that benefit your whole body.
Is it free to try?
Yes! You can download and use Longist for free. Premium features (like personalized reports or pro longevity plans) may come later, but the core experience—scanning meals and seeing your life gain—is free for everyone.
