# SmartGo One vs Qubic

The clearest difference is in-app purchases: Qubic at none against SmartGo One's 47. Qubic also leads on iOS requirement (13.0 vs 26.0). SmartGo One's advantage is ratings volume (2K vs 15) and update cadence (every 10 days vs every 2 months). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. SmartGo One sells 47 in-app purchases, starting at $4.99 per month. Qubic asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.8 for SmartGo One against 4.7 for Qubic. That said, the two scores are not equally well evidenced: SmartGo One has 2K ratings behind it against 15, so its average is the more settled of the two. Written reviews are what separate them: 77% of SmartGo One's written reviews are positive against 83% of Qubic's.

SmartGo One ships an update every 10 days, Qubic every 2 months. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
