# VirtualPhoneSystem vs String

The clearest difference is review sentiment: String at 69% against VirtualPhoneSystem's 0%. String also leads on update cadence (every 2 months vs every 5 months) and ratings volume (62 vs 9). VirtualPhoneSystem's advantage is rating (4.0 vs 3.5) and monetization model (free vs free with in-app purchases). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

VirtualPhoneSystem holds the better App Store score, 4.0 against 3.5. That said, the two scores are not equally well evidenced: String has 62 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 0% of VirtualPhoneSystem's written reviews are positive against 69% of String's, so the app with the better star average is not the one people write more warmly about.

VirtualPhoneSystem ships an update every 5 months, String every 2 months. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
