Reputation

Hokusai is regarded as a capable mobile multitrack editor, praised for its precise waveform editing and extensive pro effects comparable to desktop tools like Audacity. Users appreciate Audio Copy/Paste integration for app workflows. Some note the pro upgrade is necessary for full functionality, and the interface can feel dated. Last App Store update in September 2025 indicates ongoing maintenance.
