AI-powered tools (in recent version): Stem separation, vocal remover make it highly powerful.

Fun effects: Voice changer, reverb, pitch effects add a creative dimension.
-
Good for both casual and pro users: Beginners can do basic trimming / recording, while more advanced users can use mixing, noise removal, and stem separation.
-
Cost-effective: The base app is free; premium features via in‑app purchases. On Android, many features are already quite powerful even in free version. (Grand Screen)
-
Frequent updates: The app is actively maintained (recent version 1.3.10). (APKPure.net)
Cons / Limitations
-
Learning curve: Because it has so many features, beginners might feel overwhelmed at first.
-
Ads / In‑App Purchases: To unlock all advanced features, you may need to pay. (Different plans on iOS: monthly or yearly.) (App Store)
-
Performance on large files: Some users note that loading very large audio libraries can be slow or laggy. (Grand Screen)
-
AI stem separation quality: As with many AI tools, the quality of separation (vocals / instruments) may not always be perfect — depends on the source track.
-
Mobile limits: While powerful, it's still limited by your phone’s CPU / memory. For super high-level pro audio production, a desktop DAW might be better.
-
Export limitations: There may be limitation for format or bitrate for some users depending on platform / version.
