Disclosure: we make Beacon, one of the apps this guide covers, so Beacon is not ranked. It has its own section, Where Beacon Fits, after the list.
Updated 27 September 2026: we re-checked each app against its own pricing page and its App Store listing. Two of the four are iPhone only, one is a beta you have to join a waitlist for, and the order below changed as a result.
Quick Answer
Longevity is not one number. It is the sum of daily habits: how you train, eat, sleep, and recover over years. The best AI longevity app is the one that improves those habits, not just the one that shows you an aging score. We rank the apps in this order: whether you can install and use one today, then how well it coaches daily habits, then wearable support and aging scores, using the comparison table below. The Longevity AI leads, because its App Store listing is free with no in-app purchases and it coaches across activity, diet, sleep and mindfulness. Humanity is the pick for a rate-of-aging score. Longist is best for longevity-scored food logging. Neura has by far the widest device list here, and it is last, because it is still in beta behind a waitlist.
The catch: on an Android phone this category barely exists. Humanity's US listing names only iPhone and Apple Watch. Longist is on the App Store and runs a waiting list for Android. Neura is the only one of the four that names Health Connect and Samsung Health, and it is the one you cannot simply download. If you are on Android, treat this page as a watch list rather than a shopping list.
What an AI Longevity Coach Should Actually Do
Aging scores are motivating, but a score is a mirror, not a plan. The levers that research links to healthspan are familiar: strength and cardiovascular training, protein and whole-food nutrition, sleep regularity, and recovery. A useful longevity app coaches those levers day to day and adapts as your data changes. The best ones read your wearables so the guidance is based on your body, not a generic template.
Best AI Longevity Apps by Use Case
- Best free coach you can install today: The Longevity AI
- Best rate-of-aging score: Humanity
- Best longevity-scored food logging: Longist
- Widest device list, if you can get a beta spot: Neura
1. The Longevity AI - Best Free Coach You Can Install Today
Best for: People who want coaching across activity, diet, sleep and mindfulness without paying.
The Longevity AI comes from Longr UK Ltd. Its US App Store listing is free, shows no in-app purchases, and says there are no ads and every core feature is free for life. The listing describes AI longevity coaching with wearable insights, nutrition tracking, sleep and activity dashboards, and a biological age estimate, organised around four areas: activity, diet, sleep and mindfulness.
Where it falls short: the listing never names which wearables it reads, so you cannot tell before installing whether your ring or watch is supported. Structured strength programming is not part of it either. A free app with no in-app purchases also has no obvious revenue, which is worth keeping in mind before you make it the home for years of health data.
2. Humanity - Best Rate-of-Aging Score
Best for: iPhone owners who want one number that tracks how fast they are aging.
Humanity, from Humanity Incorporated, estimates a biological age and a rate of aging from movement and heart rate data, and awards an H Score for actions across movement, nutrition, mind and recovery. Its listing says you can upload blood test results for a blood age estimate as well. The score is a clear, motivating signal, and the app has been in the category long enough to have history behind its numbers.
Where it falls short: the US listing names only iPhone, Apple Watch and Apple Health, with no Android version. It installs free, but its in-app purchase list runs from $11.99 to $82.99 for Premium plus a $179.99 Pro entry, so what you actually pay depends on which of those you are offered rather than on a single published price. It stays a measurement product more than a daily coach for training and nutrition.
3. Longist - Best Longevity-Scored Food Logging
Best for: iPhone users who want nutrition framed around longevity.
Longist turns a photo of a meal into a longevity score expressed as time added or removed: its own site uses a bacon cheeseburger at minus 2.3 hours and baked fish at plus 1.8 hours as the worked examples. It reads Apple HealthKit for steps and activity, resting and active heart rate, heart rate variability, sleep, VO2 max and hydration, and personalises its goals from that data.
Where it falls short: Longist is iPhone only, and its site offers a waiting list for Android rather than a Google Play release. Its site does not publish a subscription price anywhere we could find, so you learn the cost inside the App Store listing. The claim on its home page that the app helps you gain up to 13 healthy years is marketing, not something it measures for you.
4. Neura - Widest Device List, If You Can Get a Beta Spot
Best for: People with several devices who are willing to wait.
Neura is an AI health coach that reads the wearables and apps you already use and turns them into a daily plan with micro-tasks. Its integrations page claims more than 50 apps and devices, and names Apple Health, Health Connect, Samsung Health, Garmin, Fitbit, Oura, Withings, Polar, Suunto, Coros, Ultrahuman and Zepp among them. That is the broadest list on this page by a wide margin. WHOOP is not on it.
Where it falls short: Neura's own site says the product is in beta and sends you to a waitlist instead of a download, which is why it sits last here despite the device support. Its free Neura Basic tier is capped hard: one integration, one active goal, a sync once a day, five widgets and no longevity widget. The longevity widget, real-time sync and full metric set sit in Neura iQ at $29 a month, after a 7-day trial. That is more than twice what most apps in this guide charge.
Longevity Devices and Tracking Tools for Beginners
None of the apps above is a tracker. Each one reads a device you already wear, so the first question is not which app to buy but which device will feed it. For longevity the useful signals are the slow-moving ones: resting heart rate, heart rate variability, sleep duration and consistency, and VO2 max. A smart ring, a wrist tracker or a running watch will record most of that. What separates them in practice is how much of it reaches the app you want to use.
If you are starting out, the binding constraint is usually your phone rather than your wrist:
- On an iPhone: all four apps are open to you. Anything that writes to Apple Health, including an Apple Watch, an Oura ring or a Garmin watch, can reach Humanity, Longist and The Longevity AI without a direct integration.
- On Android: the list collapses to Neura, the only app here that names Health Connect and Samsung Health, and it is still a waitlist beta. Humanity has no Android version and Longist has a waiting list.
Note that Apple Health is a floor, not a ceiling. Some metrics never make the trip: a device can record heart rate variability and still keep it inside its own app, in which case a longevity app reading Apple Health will never see it. Check the metric you actually care about, not just the brand name on the integration list.
For which hardware to buy, rather than which app to pipe it into, our best wearables for longevity page ranks the devices themselves.

Which Longevity App Should You Choose?
- You want free coaching across the basics: choose The Longevity AI.
- You want a clear rate-of-aging number on an iPhone: choose Humanity.
- You want nutrition framed around longevity: choose Longist.
- You own several devices and can wait for a beta spot: choose Neura.
- You are on Android: none of the four is a safe recommendation today. Neura is the only one that lists Health Connect, and it is not generally available.
A longevity score tells you where you stand. A coach helps change where you are going. Whichever you choose, check which of your wearables it reads and what stays free. For deeper background, see our guide to the best AI health coach apps.
Where Beacon Fits
We make Beacon, so it is not in the ranked list above. Here is what it offers for long-term health habits and where it falls short, checked against Beacon's help center and integrations page.
What it does: Beacon runs on iPhone, and the iPhone version includes an Apple Watch app. It logs food and workouts, calculates Sleep, Exercise, Diet, Focus and Mindfulness scores, and uses them to decide when your daily plan suggests a rest day. Beacon graphs each of its category scores over time, so a change in sleep or diet is visible as a trend rather than a single day. Beacon does not order blood tests and does not interpret or diagnose results.
Where the data comes from: WHOOP, Oura and Withings connect directly, and devices like Garmin arrive only through what their apps write to Apple Health. Fitbit data has no route into Beacon today. Beacon is iPhone-only, so there is no Android route at all. Beacon also reads Apple Health, which is the route everything else takes in.
What Beacon Premium covers: at $19.99 a month or $119.99 a year, food and workout logging, every health data connection, AI coaching, AI-generated workouts, workout suggestions and choosing which device powers each metric.
Limits to know:
- What crosses over is the measurement, not the verdict. Beacon reads HRV, resting heart rate, sleep stages and sleep performance and computes its own five category scores from them. Other companies' scores — Oura's Readiness, WHOOP's recovery percentage, Garmin's Body Battery and Training Readiness — are not shown in Beacon.
- There is no direct Garmin, Coros, Polar or Ultrahuman connection. Those reach Beacon through Apple Health, so whatever the device declines to share with it does not arrive.
FAQ
What is the best AI longevity app in 2026?
On this guide's criteria, which put availability first and daily habit coaching second, The Longevity AI leads: its US App Store listing is free with no in-app purchases and covers activity, diet, sleep and mindfulness. Humanity is the pick for a rate-of-aging score, Longist for longevity-scored food logging, and Neura has the widest device list but is still in beta behind a waitlist. We make Beacon, so it is not ranked here.
What are the best longevity tracking devices for beginners?
Start with the metrics rather than the brand. The signals that matter for longevity are the slow-moving ones: resting heart rate, heart rate variability, sleep duration and consistency, and VO2 max. A smart ring, a wrist tracker or a running watch will record most of them. The thing that catches beginners out is the phone, not the device: Humanity is iPhone only, Longist runs an Android waiting list, and Neura is the only app on this page that names Health Connect. Our best wearables for longevity page ranks the hardware itself.
Is there a longevity app for Android?
Not a straightforward one today. Of the four apps here, Humanity's US App Store listing names only iPhone and Apple Watch, Longist is on the App Store with a waiting list for Android, The Longevity AI is listed on the App Store, and Neura names Health Connect and Samsung Health but is in beta behind a waitlist. Beacon, which we make, runs on iPhone and reads Apple Health.
Do longevity apps measure biological age?
Some do. Humanity estimates a biological age and a rate of aging from movement and heart rate data, and its listing says you can add blood test results. Others focus less on a single age number and more on the daily habits that research links to healthspan, such as strength training, nutrition, sleep regularity, and recovery.
Is there a free AI longevity coach?
Yes. The Longevity AI's US App Store listing is free and shows no in-app purchases. Neura has a free Basic tier, but it is limited to one integration, one active goal and a sync once a day, with the longevity widget reserved for Neura iQ at $29 a month. Beacon, which we make, covers food and workout logging, every health data connection and AI coaching in one subscription, Beacon Premium.
Can an app actually help me live longer?
No app can promise a longer life. What a good longevity app can do is help you consistently improve the habits associated with better long-term health. These apps are informational and not a substitute for medical care.
