# DPI vs Gbox

The clearest difference is rating: DPI at 4.7 against Gbox's 3.5. DPI also leads on review sentiment (60% vs 38%) and ratings volume (1.1K vs 31). Gbox's advantage is ads (none vs shown) and iOS requirement (10.0 vs 18.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. DPI sells 1 one-off in-app purchase and Gbox sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

DPI holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: DPI has 1.1K ratings behind it against 31, so its average is the more settled of the two. Written reviews point the same way: 60% of DPI's written reviews are positive against 38% of Gbox's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 24, 2026 and October 26, 2026 respectively.
