Longist

Photograph a restaurant menu or your dinner plate and Longist tells you how those food choices are likely to affect your lifespan.

It is a food tracking app built around longevity and healthspan rather than calories and macros, and the feedback arrives minute by minute.

The scoring draws on research from leading universities and a Nature Food study.

The AI Longevity Coach gives personalized guidance, but it is a premium feature and the free plan does not include it.

The free plan covers the core features.

Longist connects to Apple Health, and health data stays on your device.

Meal recognition relies on AI, so expect the occasional misidentified dish.

Weight loss is not the goal, though it may follow as a side effect.

Subscriptions renew automatically unless you turn that off yourself.
