User Reviews

Overall, users like the app as a PC-free UTau/Vocaloid-style mobile tool, especially its ability to import UTau voicebanks and use personal voices. Monetization via points/ads and a premium tier is a common complaint. Frequent bugs (MIDI/UST speed issues, freezes) and limited voicebank/library support hinder usability. Onboarding and English tutorials could be clearer. Despite these flaws, many appreciate ongoing updates, community support, and the option to access voices through ads/points, making it worthwhile for voicebank enthusiasts who can tolerate the downsides.

Pros

Import UTau/UTAuloid voicebanks on iPhone for PC-free vocaloid-style music creation
Support for using personal voicebanks beyond built-in options
Mobile-friendly and simpler workflow compared to desktop tools
Access to many voicebanks via ads/points (downloadable voices)
Active developer community with updates and Discord support

Cons

Premium paywall and points for imports; ads required to earn points
Stability issues: app freezes/crashes on devices
Import/read issues with certain file types (MIDI/UST) causing tracks to play too fast or not read moras
Voicebank/library limitations and bugs (difficulty accessing VOICEVOX library; some voicebanks show errors)
Onboarding/tutorial gaps and language quality; confusing for beginners; features like dark mode often behind paywall
