Longist

Longist is an iOS AI longevity coaching app for biohackers and longevity enthusiasts who want data-driven feedback on how everyday food choices may affect healthspan.

Key capabilities include:

• Meal analysis by photo, menu, or barcode, translating what is eaten into estimated minutes added or lost and showing dish-level ingredient and nutrient breakdowns
• A Longevity Score and progress views that quantify changes over time based on logged meals and habits
• An AI Longevity Coach (chat) that provides personalized guidance based on prior consumption, including what to eat next and when
• Apple Health (HealthKit) integration to incorporate activity and biometric signals (for example steps, heart rate, sleep) into recommendations and goals

Pricing: Freemium with an auto-renewing subscription; pricing shown includes $24.99/month and $179.99/year, plus a 3-day free trial.

Notable for its longevity-first framing, it focuses on minutes and healthspan impact rather than calorie and macro counting, and positions meal scoring around a nutrition index referenced from a Nature Food study.
