# PTERS vs GGUZUNI

The clearest difference is review sentiment: GGUZUNI at 97% against PTERS's 48%. PTERS's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

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

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on November 2, 2026 and November 7, 2026 respectively.
