Verdict
MaX UC and NimbusPhone both sit at 4.1 stars, but that hides the real split: 40% of NimbusPhone's written reviews are positive against 18% of MaX UC's. MaX UC's advantage is ratings volume (1.1K vs 20) and update cadence (every 2 months vs every 4 months). On price, rating, ads and in-app purchases there is nothing between them.
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. Neither carries in-app purchases, so what you see is what you pay.
MaX UC holds the better App Store score, 4.1 against 3.9. That said, the two scores are not equally well evidenced: MaX UC has 1.1K ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 18% of MaX UC's written reviews are positive against 40% of NimbusPhone's, so the app with the better star average is not the one people write more warmly about.
MaX UC ships an update every 2 months, NimbusPhone every 4 months. The most recent releases landed on September 24, 2026 and September 9, 2026 respectively.
