# SIMPlus vs UUID

The clearest difference is rating: UUID at 5.0 against SIMPlus's 3.6. UUID also leads on in-app purchases (none vs 10) and review sentiment (50% vs 41%). SIMPlus's advantage is ratings volume (157 vs 1) and update cadence (fortnightly vs every 2 months). On price, ads and device support there is nothing between them.

Both are free to download. SIMPlus sells 10 one-off in-app purchases. UUID asks for nothing beyond the download.

UUID holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: SIMPlus has 157 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 41% of SIMPlus's written reviews are positive against 50% of UUID's.

SIMPlus ships an update fortnightly, UUID every 2 months. The most recent releases landed on September 21, 2026 and September 6, 2026 respectively.
