VibeBlocks is an AI Coding Lab where you learn coding with AI by building real projects, from on-screen art and games to Arduino, Micro:bit, and Physical AI hardware, all on your phone. It is built for students, beginners, makers, teachers, coding clubs, and classrooms. Instead of watching passive lessons or accepting the first answer from AI, you learn through a practical loop: describe what you want, read what AI made, test it, and redirect it until it works. Directing AI is the coding literacy of the AI era, and VibeBlocks is built to teach it. Start in Creative Lab Creative Lab is where ideas come to life. Make interactive art, games, visual experiments, and small prototypes by describing what you want to build. AI drafts the first version; the learning starts when you inspect it, run it, compare the result with your intention, and improve it step by step. This is vibe coding for learning Vibe coding is not only for apps and websites. In VibeBlocks, you practice vibe coding across creative coding, game coding, block coding, Arduino, Micro:bit, and Physical AI projects. The goal is not just to generate code. The goal is to understand what changed, why it works, and how to direct AI better next time. Build from screen to hardware Begin with projects on the screen, then move toward real sensors, motors, circuits, and robots. VibeBlocks connects creative coding, STEM learning, and physical computing in one mobile flow, with no PC required. What you can build and practice: - Interactive art and creative coding projects - Games and MakeCode Arcade-style game logic - Block coding for beginners, plus the bridge from blocks to real code - Arduino coding with a built-in circuit simulator - Micro:bit coding on mobile - Sensor, motor, LED, buzzer, and display projects - Physical AI and robotics challenges with motion and behavior - Reading, testing, debugging, and improving AI-generated code How it works: 1. Create: tell AI what you want to make 2. Inspect: read the code, blocks, or behavior AI created 3. Test: run the project on screen or in the simulator 4. Redirect: change the prompt, logic, or settings 5. Build again: improve the result and learn from the process Why VibeBlocks is different: - One app for AI coding, block coding, game coding, Arduino, Micro:bit, and Physical AI - Teaches you to direct AI, not just consume its output - 39 structured courses with 365+ lessons, plus missions and a free creative space for your own ideas - Takes you from first idea to working project without starting from a blank page - Works for classrooms, coding clubs, workshops, and self-study The VibeBlocks team has built hands-on coding education for 9 years, used in classrooms and national programs across Korea, Kazakhstan, Malaysia, and the Middle East. Formerly MAKE, VibeBlocks carries the same learn-by-making DNA into the AI era. FAQ Q. Do I need a PC or a hardware kit? A. No PC and no kit needed — even the Arduino circuit simulator runs right on your phone (an internet connection is required). Real hardware is optional, for when you want to take projects further. Q. Do I need coding experience? A. No. Start with block coding and guided courses; AI explains everything you build along the way. Q. Can schools and clubs use it? A. Yes. VibeBlocks supports classroom, coding club, and workshop use, with structured courses and missions. Download VibeBlocks, tell AI your first idea, and learn to direct it into something real. Your first project takes minutes, not weeks.

Verdict
The clearest difference is ads: BlueGrays at none against VibeBlocks's shown. BlueGrays also leads on rating (4.2 vs 3.8) and update cadence (every 4 days vs every 2 weeks). On price, ratings volume, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. VibeBlocks sells 5 one-off in-app purchases and BlueGrays sells 10 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
BlueGrays holds the better App Store score, 4.2 against 3.8. Both are backed by a comparable volume of ratings — 8 and 14 respectively. Written reviews point the same way: 50% of VibeBlocks's written reviews are positive against 64% of BlueGrays's.
VibeBlocks ships an update every 2 weeks, BlueGrays every 4 days. The most recent releases landed on November 7, 2026 and November 12, 2026 respectively.
