# USB Simulator 2015 vs Ignis

The clearest difference is rating: Ignis at 4.7 against USB Simulator 2015's 3.3. Ignis also leads on update cadence (every 6 weeks vs every 11 months) and ratings volume (7.9K vs 50). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. USB Simulator 2015 sells 2 one-off in-app purchases and Ignis sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
