Verdict
The clearest difference is update cadence: Decodex at every 2 days against Nonoverse's fortnightly. Decodex also leads on rating (5.0 vs 4.8) and review sentiment (100% vs 91%). Nonoverse's advantage is ratings volume (39 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Nonoverse sells 6 one-off in-app purchases and Decodex sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Decodex holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Nonoverse has 39 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 91% of Nonoverse's written reviews are positive against 100% of Decodex's.
Nonoverse ships an update fortnightly, Decodex every 2 days. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
