# PUC Mobile vs SAM4 Online

The clearest difference is rating: SAM4 Online at 5.0 against PUC Mobile's 3.6. PUC Mobile's advantage is in-app purchases (none vs 1) and update cadence (every 2 months vs every 6 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. SAM4 Online sells 1 one-off in-app purchase. PUC Mobile asks for nothing beyond the download.

SAM4 Online holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: PUC Mobile has 5 ratings behind it against 1, so its average is the more settled of the two.

PUC Mobile ships an update every 2 months, SAM4 Online every 6 months. The most recent releases landed on June 5, 2026 and September 18, 2026 respectively.
