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. Merge Explorer sells 4 in-app purchases, starting at $9.99 per month. UDC.gal asks for nothing beyond the download.
Merge Explorer holds the better App Store score, 4.1 against 3.5. That said, the two scores are not equally well evidenced: Merge Explorer has 279 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 38% of UDC.gal's written reviews are positive against 46% of Merge Explorer's.
Both ship on a similar rhythm, roughly monthly. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
