# Zadx vs Sudoku

The clearest difference is ads: Zadx at none against Sudoku's shown. Zadx also leads on iOS requirement (14.0 vs 17.0). Sudoku's advantage is update cadence (every 4 days vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Zadx sells 3 one-off in-app purchases and Sudoku sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Zadx ships an update every 2 months, Sudoku every 4 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
