# X Lines vs Dr. Virus

The clearest difference is rating: X Lines at 5.0 against Dr. Virus's 2.5. X Lines also leads on update cadence (every 6 days vs every 2 months) and iOS requirement (9.0 vs 12.0). Dr. Virus's advantage is in-app purchases (none vs 1) and ratings volume (24 vs 2). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. X Lines sells 1 one-off in-app purchase. Dr. Virus asks for nothing beyond the download.

X Lines holds the better App Store score, 5.0 against 2.5. That said, the two scores are not equally well evidenced: Dr. Virus has 24 ratings behind it against 2, so its average is the more settled of the two.

X Lines ships an update every 6 days, Dr. Virus every 2 months. The most recent releases landed on October 2, 2026 and October 7, 2026 respectively.
