Good questions, clear answers
Before you press play.
Can ToneEQ EQ every app on my iPhone?+
No. iOS does not provide a public way for third-party apps to process the system-wide audio of other apps. ToneEQ applies software EQ to supported audio played by its own audio engine.
Does EQ work with Apple Music?+
ToneEQ can browse and control your Apple Music library through Apple’s MusicKit player. Protected Apple Music audio remains platform-managed, so software EQ is clearly shown as unavailable.
Which audio files are supported?+
ToneEQ is designed for common local formats including MP3, AAC/M4A, ALAC, FLAC, WAV and AIFF, subject to final release compatibility testing.
Is basic EQ really free?+
Yes. The free core includes 10-band graphic EQ, parametric EQ, local playback and one device-bound sound profile. Pro is for multiple devices, multiple saved profiles, listening match and cloud sync.
Does ToneEQ upload my music?+
No. Audio files, track titles and complete file paths are not uploaded by ToneEQ. Optional cloud sync is for sound profiles and settings—not your music.
