# JSON Master vs MindWiki

The clearest difference is ads: MindWiki at none against JSON Master's shown. MindWiki also leads on rating (5.0 vs 4.6) and update cadence (every 4 days vs every 9 days). JSON Master's advantage is device support (3 vs 1). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.

Both are free to download. JSON Master sells 3 in-app purchases, starting at $2.99 per 7 days and MindWiki sells 4 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.

MindWiki holds the better App Store score, 5.0 against 4.6. Both are backed by a comparable volume of ratings — 5 and 4 respectively. Written reviews split almost evenly too, at 100% and 100% positive.

JSON Master ships an update every 9 days, MindWiki every 4 days. The most recent releases landed on October 3, 2026 and October 1, 2026 respectively.
