Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Idle Dragons sells 7 one-off in-app purchases. Monster Merge! asks for nothing beyond the download.
Idle Dragons holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Monster Merge! has 22 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 67% of Idle Dragons's written reviews are positive against 100% of Monster Merge!'s, so the app with the better star average is not the one people write more warmly about.
Idle Dragons ships an update every 3 weeks, Monster Merge! every 3 months. The most recent releases landed on October 15, 2026 and September 25, 2026 respectively.
