# Onebox vs VirtualPhoneSystem

The clearest difference is rating: VirtualPhoneSystem at 4.0 against Onebox's 3.0. VirtualPhoneSystem also leads on monetization model (free vs ad-supported) and iOS requirement (9.3 vs 15.0). Onebox's advantage is review sentiment (35% vs 0%) and update cadence (every 4 weeks vs every 5 months). 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 3.0. That said, the two scores are not equally well evidenced: Onebox has 46 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 35% of Onebox's written reviews are positive against 0% of VirtualPhoneSystem's, so the app with the better star average is not the one people write more warmly about.

Onebox ships an update every 4 weeks, VirtualPhoneSystem every 5 months. The most recent releases landed on October 14, 2026 and October 3, 2026 respectively.
