I built an iOS app for anti-ageing (FREE). 👀 Help people slow ageing by fixing daily habits. What the app does: > Calculates your biological health > Gives a daily protocol for exercise, nutrition, sleep, and mental health > Focuses on cellular health > Tracks streaks to build consistency > Unlocks badges & achievements to keep motivation high > No sign up > No Backend: Your data is always yours > Lets users set personal health goals > I’ve moved paid features into the free version > so people can actually use it and see results.

Today, I am excited to introduce Bevel Intelligence, the first AI Health Companion that brings together every pillar of health and proactively helps you become the best version of yourself. This is part of our 2025 Summer Release, the biggest update in Bevel’s history. Alongside Bevel Intelligence, we’ve added major upgrades to Nutrition (custom foods, macro goals, recipe importing), Strength Builder (live sync, supersets, AI-generated workouts), a redesigned Action Button, and support for new languages. In total, we’re shipping 63 new features and improvements. Bevel has always helped you track your sleep, recovery, training, and nutrition. But those insights were buried in charts and data. Bevel Intelligence changes that. It brings the bigger picture of your health to the surface and gives you guidance in real time, while keeping you in control with complete privacy. This is the next chapter for Bevel: not just tracking your health, but truly understanding it. The update is available now on the App Store. Let us know what you think. Welcome to a new era of personal health!

built and deployed an AI Ad Analysis Tool on my vibe marketing resource site today... steps: 1) I've managed $150m+ in campaigns so used my knowledge to have Manus build out a super detailed scope using weights for various factors 2) loaded the scope into Replit and it basically one shotted the app! it uses reasoning models from OpenAI 3) went back and forth with Replit agent to update the overall design and UX 4) now we have tools, super cool. did some testing and everything is working with beehiiv Give it a try and lmk what you think... THIS IS VIBE MARKETING. Stack: - Replit - Manus - OpenAI - Beehive

Sage and I traveled to Switzerland to undergo blood filtration and I wanted to share it with you guys. The procedure itself was completely painless, and every step was monitored with an EEG, heart monitor, and continuous blood pressure tracking. What fascinated me most was seeing my blood before and after the treatment. Before, many of my red blood cells were stacked together in what's called rouleaux formation, which is commonly seen in venous blood. After the filtration, they appeared much more separated, giving each cell more surface area to exchange oxygen, remove waste, and interact with its environment. It's important to remember that looking at blood under a microscope isn't a standalone diagnostic tool, and you can't judge your overall health from a single image alone. But seeing the changes firsthand was an incredible experience and sparked some fascinating conversations about blood health, circulation, and recovery. Would you ever try something like this?

Productivity agents optimize work. Macaron takes the opposite approach: “Other AI agents help you work. Macaron helps you live better.” This AI app focuses on everyday life, health, relationships, and hobbies—rather than on optimizing work. In this example, the app independently generates its own calorie tracker app! Through prompting, one app replaces countless apps that would otherwise have to be downloaded individually from the app store. By simply chatting with Macaron about what you need, Apps are created within Macaron behind the curtain. Example: "Macaron, I want an app to log daily food calories and help me control my calorie intake."

I built a mobile app to check Paddle revenue (because they don't have one): 👉 - Use your Paddle API key (read-only and scoped) - Live data with beautiful and useful graphs built with native Swift UI. - Multi-account supported, unified revenue metrics. - Data stay on device, no server (api requests are sent directly from your phone) - Home widgets - I made it free to download on App Store (once it's approved) - Buy the source code for $19 and customize it however you want (save 5hrs of prompting if you try to do it yourself). Some interesting facts about this side project: - I vibe coded with 100% claude code remotely on my Mac Mini (with my AI assistant setup) in less than 24 hours. - I have read 0 line of code in this project and never opened Xcode myself. - My AI assistant designed the app with GPT Image 2, built the app with Swift UI, test it on simulator (via screenshots), send the test build to TestFlight for me to test, and invited me to the app store connect account so I can test on my phone, then the AI submitted the app to App Store and currently waiting for approval. - For the website, I ask it to come up with a domain name, I bought it via manually and give it access via Cloudflare API, the AI design and create a static website with GitHub, test it with lighthouse CLI, deploy via GitHub pages, config the domain DNS, deploy the website. - Then I sign up an account with Polar payment, create an API key and ask the AI to setup a store, add payment, link with the account, and add the payment to the website. The entire process happened in the last 24 hours with me only talking to the AI via Telegram. This is such a fun side project not only to create an app that I wish exists, but also to push the limit of what I can use AI for, and so far I'm very impressed. I'll create so much more apps! It feels like I have unlocked a super power.

Mei runs on a 2year old LENOVOIDEAPAD SLIM 3 16ABR8 R5 16" - 16gb RAM - 2tb external SSD. I talk with it through TG It does : - research (ads sources) - Formating - push to typefully for review ( can also schedule posts ) - update my other agents to ensure they are not hallucinating. - keeps log of my daily tasks and reminds me / helps me achieve them It uses : Ollama for most of the tasks, API calls to ensure minimum token burn, and only uses Opus if uncertain or I trigger it. Next stage - OpenClaw integration and 1h - 6h - 12h test runs before full integration.

🐨: To be honest I’m still scared of the night even now. I’m scared of the fact that I have to sleep. Lying down and being still for 3 to 4 hours is truly hell. 🐨: Hence even now I’m scared of the night. Also there were a lot of times when I came out on vacation, drank a lot and just passed out. 🐨: The hospital director/doctor I go to said ‘it might be because you’re in the military, you will get better when you’re out’ and so I’m getting my daily routine back on track again and we’re lowering my medicine dose little by little to completely go off it. 🐨: To be honest, half of my diary is filled with my sleep problem story. Because I really couldn’t sleep.

When an injury forced Eric to quit football, he channeled the change into motivation — to lose weight, to adopt new health practices, and to dial in his daily routine. “I gain momentum through routines. Whether that’s physical fitness, mental wellness, or nutrition, it’s easier to choose the right way to do things when you've been doing that.” Some of Eric’s routines? Incorporating cardio into his workouts to round out his fitness. Sauna and cold plunge for recovery. Prioritizing sleep. Drinking more water — and drinking LMNT with it to replace what he’s losing in sweat. “My fitness and wellness have transitioned into a bigger and more expansive role. I had one job to do on a football field, and the way I train now allows me to be much more versatile in life. “I've gotten better at listening to my body. And I feel comfortable knowing that whatever I need to do, I can.”

Quick demo of the Claude Code system I built to generate hundreds of Meta ad creatives with Nano Banana, upload them to Meta automatically, and manage performance from one place. No need to log into Ads Manager at all 🙏 everything is uploaded via API and performance data can be pulled back on demand by chatting to Claude. Super valuable as a solo founder, it feels like it's my virtual marketing team 😂 Surprisingly straightforward to set up too. I’m sharing a write-up of the basics in my newsletter later today!

My ads are now completely automated using Codex. It writes the script, uses HeyGen API to generate the video of my avatar, uses ElevenLabs for the voiceover, grabs our real mulching footage and before / after images from our Google Drive, and uses Hyperframes to make the edit. I literally just linked Steve Hunsaker | Home Service Accelerator YT channel to my AI agent after connecting resources and told it to transcribe his meta ad strategies and make 40 ad variations based off of them. That's it. The agent ran for 2 hours and spit out 40 ads with different variations. Now I'm running them and they're performing phenomenally. It's that simple now. If I need more creatives, I just click a button. Actually I don't even do that... I have a cron set up to make new ones every month 😅

✨ To prove my friend Stevie (who's visiting me in Brazil) you don't need an idea, or even a lot of time these days to ship a little app that might make money I took the top idea from "A startup that uses AI to generate personalized bedtime stories for kids based on their interests, family photos, and daily activities, delivered via a voice app. (❤️ 110 likes, 3 days ago)" So I copy pasted it into Claude Code and asked it to build it The first version of course didn't work, and I had to tell it some endpoints didn't work properly but then it fixed it The bedtime stories are generated by xAI Grok 4.1, then sent to TTS with Google AI Gemini and payment with Stripe Checkout Total time from start to live: 24 minutes

Mental Health tip for today… “Throw a party in your heart!!!” One of the best things about opening up fully about my mental health battles has been the learning journey I’ve since gone on. Now, as a result, I have new tools to fight my depression and anxiety, new rituals to navigate through that gray I live in. This is pretty cool and I learned it from a monk in Thailand (literally) and I now use it every night of my life to change what nights look like for me. I used to go to sleep absolutely dreading those first 15 minutes I laid my head on my pillow because I didn’t know how to like or love myself and I was laying there with someone I felt didn’t deserve to be liked or loved. Now, I use this tip to end my night on a MUCHHHH better plane and as a result start my day a little better. Give it a listen and if it resonates with you give it a try. Hope it helps gang! #mentalhealth #mentalhealthmatters #depression #anxiety #unbreakable

"Claude Code is the first AI tool that can actually recreate how a data scientist thinks." Here's my new episode with Sumeet Marwaha (Head of Data at Brex) on exactly how to build an AI analyst with Claude Code. We covered: ✅ 3 queries to build a data analyst MCP ✅ How to give the analyst both data + context ✅ Exclusive Brex data on which AI tools are crushing it in startups and enterprise Some quotes from Sumeet: "I've set up dashboards many times in my career. They end up getting ignored. Claude will always read it. Claude will always ask the right questions." "You have to set up Claude Code to not just look at the data. It should be able to search Slack, find the incident, and understand why your metrics look wrong." "This tool is absolutely crushing it based on our data. It's both the startup AND enterprise coding tool of choice." 📌 Watch now:

I've never seen it this hot before in the UK in June. Thinking about this from a health perspective, especially for more vulnerable groups: 1. Considering AC is not widely adopted here, it's a must to have lots of fans in the home to stay cool 2. Hydration and electrolytes are a must. And don't be short of salt intake, as it's lost when you sweat 3. You can still move your body, too many people by default become inactive at home. I got up early so I could still go outside and exercise. But even within the home, it's not good to be too sedentary 4. Avoid going out between noon and 5 pm if it can be helped during the heatwave 5. I'm also loading my body with healthy cold foods and antioxidants. England has some of the best delicious blueberries — and I'm eating loads of them! Here's my video on why blueberries are so extraordinary for health:

I finally caved to the hype. Here's my attempt at #vibecoding with *zero* manual coding. I gave myself 30 minutes to build a 3D RPG with #threejs using Cursor + Claude 3.7-sonnet. I'm honestly impressed with what it was able to generate: - Infinite terrain generation/chunking - Trees, rocks and bushes - NPC manager - Skeletons and goblins - Health bars - Combat mechanics (this is where it broke down) It only ended up failing because Cursor got confused about which files to update and I ran out of time. The code it was generating still looked solid, so I'm guessing I was hitting the limits of the context window.

I've been building a music player with Next.js for fun. Here's a quick demo of how it works (it's open source!) • Demo: • Code: If you want to learn more about how it's built, here's more details ↓ I'm using Postgres (with Drizzle) to store information about the songs and playlists. Audio and image files are stored in Vercel Blob (object storage), and the URLs are then referenced in the database. For the UI, I'm using shadcn/ui (so Tailwind CSS and Radix). This made it easy to copy/paste in some nice components, like the dropdown menus. I built the entire first version of the UI in v0 and then iterated from there, feeding it my Drizzle schema as a source in the project and having it scaffold some of the boilerplate for me: I added support for keyboard navigation (using arrow keys) or vim motions (j/k to go up/down, and h/l to go between playlists and tracks). Also, space to toggle the now playing song, and / to focus the search input. The search function has a nice utility to highlight the currently searched text on the page in yellow. Then, I was exploring how to pass metadata from my application to macOS or iOS. Turns out there's an API for that – MediaSession. Web apps can share metadata about what media is playing (title, artist, album artwork) and sync play/pause/seek with system media controls. Works across modern browsers — even integrates with iOS dynamic island and shows up on lock screens: I set up my app like a PWA – it has a manifest.json file, so it can be installed to my iOS home screen or added to my dock on macOS. On iOS, it then uses the full screen height `100dvh` (dynamic viewport) and has padding on the bottom for the safe area with the `env()` CSS function. Finally, I was able to use the Vercel AI SDK in a script to clean up the metadata on audio files I downloaded from YouTube. Bonus: I even was able to dogfood the React Compiler, which helped me fix a performance bug! That's all! It's fun to make personal software:

On iOS, it then uses the full screen height `100dvh` (dynamic viewport) and has padding on the bottom for the safe area with the `env()` CSS function. Finally, I was able to use the Vercel AI SDK in a script to clean up the metadata on audio files I downloaded from YouTube. Bonus: I even was able to dogfood the React Compiler, which helped me fix a performance bug! That's all! It's fun to make personal software:

Up to 30% of the weight lost while dieting can come from lean muscle mass—but the right training and nutrition can help you preserve muscle, which is key for metabolic health and reducing the risk of sarcopenia. You can lose fat and gain muscle at the same time—a process called body recomposition—if you train and eat strategically. The most important factor is resistance training. Lifting heavy 2–3 times per week is essential for maintaining and building muscle while losing fat. Without it, muscle mass inevitably declines. Nutrition also plays a major role. Eating in a slight calorie deficit—around 10–20% below maintenance—allows for steady fat loss without sacrificing muscle, energy levels, or training performance. Protein intake is another key priority. Research shows that consuming 1.8 to 2.2 grams of protein per kilogram of body weight per day is optimal for muscle retention and growth during a calorie deficit, and going even higher may provide additional benefits. Beyond training and nutrition, recovery is just as crucial. Adequate sleep, stress management, and tracking progress help ensure you’re making real, sustainable changes. Get this right and you have a powerful strategy to build muscle and lose fat. If you want to learn more about optimizing body recomposition, improving VO2 max, and enhancing brain health, tune into the latest episode of the FoundMyFitness podcast, where and I break it all down with insights from top experts.
