# RetroNexus vs J2ME Emulator

The clearest difference is rating: RetroNexus at 5.0 against J2ME Emulator's 2.0. J2ME Emulator's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. RetroNexus sells 3 in-app purchases, starting at $0.99 per 7 days and J2ME Emulator sells 3 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

RetroNexus holds the better App Store score, 5.0 against 2.0. That said, the two scores are not equally well evidenced: J2ME Emulator has 8 ratings behind it against 1, so its average is the more settled of the two.

RetroNexus ships an update every 6 weeks, J2ME Emulator every 3 months. Both last shipped on October 24, 2026.
