KORG STEP MASTER DANCE PRACTICE PLATFORM Tighter rhythm, more fun! STEP MASTER, the iPhone app that lets you acquire the sense of rhythm that you need for dance. In order to dance impressively, the crucial point is to keep the rhythm! This is something that even top dancers active on the world stage always keep in mind. It's easy to be distracted by flashy moves, but what really makes or breaks a performance is whether the dancer has internalized the tempo. The best way to become a better dancer is to improve your body's core strength and your sense of rhythm. STEP MASTER is a fun iPhone app that lets dancers from beginner to expert level improve their sense of rhythm as if they were playing a game. From basic steps to complex choreography, a total of 49 dance variations are provided. Each of these are clearly illustrated with motion graphics that rotate 360 degrees. It's the birth of a new dance training tool in which the accelerometer accurately detects the dancer's sense of tempo, letting you master the moves.

Verdict
The clearest difference is review sentiment: Step Master at 100% against SleepBunny's 50%. Step Master also leads on ads (none vs shown) and iOS requirement (8.0 vs 17.0.1). SleepBunny's advantage is rating (4.7 vs 1.0) and in-app purchases (none vs 3). On price and device support 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. Step Master sells 3 one-off in-app purchases. SleepBunny asks for nothing beyond the download.
SleepBunny holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: SleepBunny has 58 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of Step Master's written reviews are positive against 50% of SleepBunny's, so the app with the better star average is not the one people write more warmly about.
Step Master ships an update every 8 months, SleepBunny every 6 weeks. The most recent releases landed on October 5, 2026 and October 10, 2026 respectively.
