# Jayson vs Json Genie

The clearest difference is ads: Jayson at none against Json Genie's shown. Jayson also leads on ratings volume (425 vs 5) and chart position (#81 vs unranked). Json Genie's advantage is update cadence (every 10 days vs every 3 weeks) and iOS requirement (16.0 vs 26.0). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Jayson sells 1 one-off in-app purchase and Json Genie sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for Jayson against 4.6 for Json Genie. That said, the two scores are not equally well evidenced: Jayson has 425 ratings behind it against 5, so its average is the more settled of the two.

Jayson ships an update every 3 weeks, Json Genie every 10 days. Both last shipped on October 13, 2026.
