Indie Hacker building AI apps: 370K users 🤙 (https://t.co/BOZvk1H2cP) 40K users 🤌 (https://t.co/wHZuITsfBh) +3 stealth apps, partnered with @rork and @arcads_ai

I just spent 3 hours vibe coding a Subway Surfers-style game remake. Already built: > Full 3-lane endless runner gameplay > Procedural tracks + obstacles > Coins, combos & power-ups > Animated 3D characters > Missions, season pass & store > Daily rewards + records > Music, haptics & 60+ custom 3D icons > Tech: SwiftUI, RealityKit Still crazy how fast you can build a full game system with AI now. PS: I built the gameplay demo before, but this time I tried vibe coding the full game and open-sourced it. 😌

Claude Fable 5 is insane again. The first time, I only used it to build a 3D game clone. I just used Fable 5 inside Rork to build a new tower defense game in about 1 hour. From the initial idea → level design → heroes & monsters → in-game economy → game art → sound effects → code Each level will have different difficulty, different map upgrades, different monsters, and different bosses. Each tower weapon has unique skills, counters other weapons in different ways, and the heroes are controllable with skills that can support each other... All in one flow. This is getting crazy me again. 🙃

My phones have been successfully warmed up and the first videos have been posted successfully. I’m about to hand them over to the students I hired so they can continue making content, and 50% of the phones will be automated. My goal is still to scale to 100+ accounts and automate them to promote my apps. I just ordered a wooden phone rack, it actually looks pretty nice. 😌

This is the full video showing what I made with Rork and Claude Fable 5. It’s super simple because I wanted to test Fable 5 using completely natural language (and even in Vietnamese) to see how well it would perform without any fancy prompts and it worked surprisingly well. I simply uploaded screenshots of Subway Surfers and told it to "clone this," and it did a pretty solid job. Also, Rork already has built-in integrations to generate game art, sound effects, and 3D models, so I didn’t use any external tools at all. It cost me around 500–600 credits. As I mentioned in my previous video, I wanted to test Claude Fable 5, and since I’m a Rork partner, I had free credits to use. Right now, instead of using Claude Code and then wiring up separate 3D tools and everything else which takes way too much time and $, I just use Rork to build everything and showcase it here. So yeah, that’s my workflow.

I just try to built a Duolingo for sex app using Rork Max, the results are insanely good. Opus 4.6 was able to research and automatically generate over 25 onboarding screens, several lessons, plus create the logo and define the app’s main color palette on its own...

This AI influencer I built will helping me grow on Tiktok, YT and IG 100% organically. My 3-step system: Step 1: Create an avatar with nano banana Step 2: Generate the script with ChatGPT Step 3: Turn the script + avatar into UGC with Arcads Instead of paying $1,000 per video, I built my own AI UGC factory.

Honestly, I’ve already fully built my app using Rork Max, it’s really good with a native UI. Now it’s just about upgrading the UI to truly feel like a gamified workout app. That way, I can market it much more easily on TikTok and other social platforms. Because if the UI stays this basic, I think the market is already saturated with workout apps, so I want it to stand out and better fit with TikTok-style content. Let's go 💪

I’m back to building apps I genuinely enjoy, instead of only building apps designed to go viral. To be honest, I’ve already built three simple, single-feature apps that generate revenue surprisingly easily but I’m keeping them in stealth mode for now. I’ll share them once I reach #1 in the market, lol. Back to this project: Fable 5 was banned, but that’s fine. Opus 4.8 still works really well. A quick reintroduction: I’m building a gamified workout and gym-tracking app. This market is already crowded, but none of the existing apps truly excite me, so I decided to build one specifically for myself with polished UI/UX and a proper gamification system. Powered by Opus 4.8, Rork, and Cursor.

I’m thinking about remaking a free step-by-step series on how to set up accounts and find content to avoid getting 0 views. I’ve noticed that many people are getting very low views, whether they use a VPN or not. Meanwhile, on the 3 phones below, I only started posting less than 2 months ago. There are 6 accounts in total, and none of them are shadow banned. The average is around 10K views per post, with quite a few posts getting over 100K views. All phones are using VPNs. This has helped me get an average of 700 new users per app every day. So I think if your views are flopping, it’s likely because you set up something wrong, your content has visuals that violate TikTok’s policies, your IP is blacklisted, or simply your content isn’t good enough for TikTok to keep pushing it viral.

Waiting on Apple review (feels slow… pretty sure the review team is on Christmas break 😅). Used the time to vibe-code the onboarding again: more animations, more mascot moments → better brand recognition. Onboarding is now 14 steps before the paywall. Not sure if that’s too much, but after checking top apps in the space… most of them actually have even more 🤷♂️ Shipping while waiting. 💪 Tech Stack: – No code mobile app builder: Rork AI – Mobile: React Native (Expo) – IDE: Cursor – Frontend: Next.js – Payment: RevenueCat – Backend: HonoJS – Database: Supabase – Infrastructure: Railway – AI API: OpenAI (dropping the tech stack here because someone always asks 😂)

My app is finally ready to ship. But since Apple barely reviews on weekends (Fri–Sun), I’m taking this window to polish everything even more. Spent the evening vibe-coding: - smoother text-change animations - a clean slider animation for height/weight inputs → The whole flow feels way more alive now. If all goes well, the launch button gets pressed next week. 🚀 More shipping, less talking.

While waiting for Apple’s approval, I’ve been using my app daily to hunt down and fix potential bugs. And yeah, it’s honestly fun seeing how well it works, especially knowing that ~85% of it was built through vibe-coding 😌 Like I said before: “Vibe-coding feels amazing when you actually know how to code and understand how the system works.” Tech Stack – No code mobile app builder: Rork AI – Mobile: React Native (Expo) – IDE: Cursor – Frontend: Next.js – Payment: RevenueCat – Backend: HonoJS – Database: Supabase – Infrastructure: Railway – AI API: OpenAI (dropping the tech stack here because someone always asks 😂)

While waiting for the App Store review, I’m just vibe-coding. Using this quiet window to polish the small things that actually matter: – refining text animations so transitions feel natural – adding a clean glass animation to the water log 💧 – fixing a few annoying scale issues on iPhone SE No rush. No pressure. Just making the experience smoother, calmer, and more alive. Now we wait for Apple to do their thing (review) 😌 Tech Stack – No code mobile app builder: Rork AI – Mobile: React Native (Expo) – IDE: Cursor – Frontend: Next.js – Payment: RevenueCat – Backend: HonoJS – Database: Supabase – Infrastructure: Railway – AI API: OpenAI (dropping the tech stack here because someone always asks 😂) PS: This is the TestFlight production build, and yah… it already feels native-smooth 😌

Right now on the App Store, there are tons of arcade games making $1M+ from ads. My million-dollar idea: I can vibe-code multiple games and turn them into TikTok, but for arcade games. I just tried vibe-coding a Pac-Man game and it was insanely simple. I could code it from scratch, but that would take about 1 month. Now it takes 5 minutes with just 3 simple steps: > Prompt it with GPT-5 > Build it using Opus 4.5 on Rork > Shipped from my phone I honestly think that combined with good TikTok marketing, making $10k–$50k/month from ads is totally realistic because TikTok users love free stuff. Bruh… AI genuinely surprised me.
