Longist – The Biohacker’s Longevity Toolkit, engineered to help you gain up to 13 healthy years of life — built for biohackers, by longevity obsessives.
Longist is a life-changing app.
I’ve tried it, and I was honestly amazed by how it helped me choose the healthiest meal from an entire restaurant menu.
Just by snapping a photo of a dish, it gave me insights not only into the calories and energy, but more importantly, into the long-term impact this meal could have on my health and lifespan. That’s something I had never really thought about before.
Longist gave me a completely new perspective on food and diet. It made me start thinking beyond short-term nutrition and consider how every meal can shape my future. Absolutely eye-opening.

If you’re curious about optimizing your diet and lifestyle for a longer, healthier life, Longist is worth trying—just pair it with professional advice for major changes. The AI-powered food recognition is incredible! I snap a photo of my breakfast—say, avocado toast with eggs—and Longist instantly breaks down its nutritional impact, telling me how it affects my longevity score. For instance, it showed my veggie-heavy meals added roughly 20 minutes to my lifespan, which is motivating!

9 viewsLove hearing that, Milana! That +20 minutes is exactly what we hoped would motivate better daily choices. Thanks for the support — more smart features are coming soon! 🙌
P.S. It’s a pleasure working with you on the team — you’re a true source of inspiration, support, and motivation for all of us!

Way more actionable than Yuka. Also tracks if you overeat the same things. Example one egg is ok, 4 is not as good.

Thanks for the feedback! I'm glad you're loving the nutrient balancing feature—it’s awesome for spotting when you eat too much of something and keeping your diet in check.

Thanks! That’s exactly what we’re aiming for. Yuka is great for quick checks, but we wanted to go deeper—tracking patterns over time and helping people understand that both overconsumption and underconsumption matter. It’s not just about what you eat, but also how often and how much, as these factors ultimately impact both lifespan and healthspan.

🚀 Super excited to share Longist with you all today!
We created Longist after realizing how difficult it was to actually measure how daily choices — especially what we eat — affect our long-term health. There’s a ton of information out there, but very little that connects it personally and immediately to your life.
That's why we built Longist: an app that uses AI and science to estimate how meals, habits, and activities impact your longevity — in real time — and give you simple, actionable ways to improve it.
We believe everyone deserves to know how they can add healthy years to their life without having to decode academic papers.

We’d love your feedback, questions, and ideas! 💬
What health or longevity habits are you most curious about?
What would make a tool like this even more helpful for you?
Any features you’d love to see next?
Jump in the comments — we’re here and excited to chat! 🙌
Does it also factor in your daily activity...i mean like a feed from a health app e.g. Apple's native health app?
Longist
@manu_goel2 Yes, we integrate with Apple Health and use that data to set daily benchmarks based on your Longevity Score. It helps you improve in real time with personalized nudges across movement, sleep, and more.
It’s all about making progress visible—and actionable—every day.
Great take on nutrition! I would really like a more personal approach though in the AI conversation but that's just me.
Also if you are considering having a meaningful free tier to increase adoption feel free to reach out :)
Longist
@ioannis_bakagiannis Thanks for the feedback! Personalization is a top priority—we're making the AI feel more like a real longevity coach.
We actually offer a 3-day free tier, and most people can’t stop using it after. Would love to connect more on this!
@david_swarowski awesome to hear that! Sure hit me up

The product looks awesome!
It has tons of potential due to the trend that's going on.
Tons of possibilities to partner with industry brands about supplements etc..
However, the video is generated by AI - don't want to be a hater, but come on "Tom 52" AI ... this is the only thing that will turn me off from the product. The regular Joe won't probably notice, but for this app the target is smart educated people.
Good luck!

@lozzzko Thank you for your feedback!
We don’t hide the fact that this was created using Veo3. In fact, our team completed it in just 5 hours. We're proud to be bootstrapped and to have saved over $100,000 in costs — this allows us to make the product itself accessible to more people so they can live healthier lives. Regarding the names — we aimed to show role models and ideal customer profiles that users can identify with.
We hope you enjoy the product as much as we do.
@david_swarowski Product is awesome!
I’ve used the app for meals I’ve thought were healthy, but realized they’re not! Helped me through some choices with my food.
Longist
@liliana_khachaturyan Love that! Realizing what’s actually healthy and can add minutes to your life is a game-changer — glad we could help!
This app has helped me make smarter choices about food, and I have gained knowledge about nutritional facts about my food that I consume!
