# DUNGMORI vs Riki

DUNGMORI and Riki both sit at 5.0 stars, but that hides the real split: 77% of Riki's written reviews are positive against 64% of DUNGMORI's. DUNGMORI's advantage is update cadence (every 6 days vs every 2 weeks) and ratings volume (21 vs 6). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. DUNGMORI sells 42 one-off in-app purchases and Riki sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

DUNGMORI holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 21 and 6 respectively. Written reviews complicate that: 64% of DUNGMORI's written reviews are positive against 77% of Riki's, so the app with the better star average is not the one people write more warmly about.

DUNGMORI ships an update every 6 days, Riki every 2 weeks. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
