# iCircuit vs VibeBlocks

The clearest difference is price: VibeBlocks at Free against iCircuit's $12.99. VibeBlocks also leads on in-app purchases (none vs 2). iCircuit's advantage is ads (none vs shown) and ratings volume (156 vs 8). On rating, update cadence and device support there is nothing between them.

VibeBlocks is free to download; iCircuit costs $12.99 up front. iCircuit sells 2 in-app purchases, starting at $1.99 per month. VibeBlocks asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 3.9 for iCircuit against 3.8 for VibeBlocks. That said, the two scores are not equally well evidenced: iCircuit has 156 ratings behind it against 8, so its average is the more settled of the two. Written reviews are what separate them: 61% of iCircuit's written reviews are positive against 50% of VibeBlocks's.

iCircuit ships an update every 4 weeks, VibeBlocks every 2 weeks. Both last shipped on November 13, 2026.
