Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Atomus HD costs $3.99 and Niki Play $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Niki Play holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Atomus HD has 60 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 91% of Atomus HD's written reviews are positive against 0% of Niki Play's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 4 months. The most recent releases landed on September 22, 2026 and June 3, 2026 respectively.
