# Viidure vs GrayBox

The clearest difference is rating: GrayBox at 5.0 against Viidure's 4.4. GrayBox also leads on update cadence (every 3 days vs monthly). Viidure's advantage is ratings volume (13K vs 1) and chart position (#95 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Viidure sells 6 one-off in-app purchases and GrayBox sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

GrayBox holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Viidure has 13K ratings behind it against 1, so its average is the more settled of the two.

Viidure ships an update monthly, GrayBox every 3 days. The most recent releases landed on November 3, 2026 and October 24, 2026 respectively.
