iOS harmonizer apps vs hardware pedals - any good alternatives?

Looking for harmonizer recommendations!
Ideally something with Eventide H90-level quality.

Tried these apps with disappointing results:
• BLEASS Voices
• Voice Synth Live Auto Pitch Vocoder
• MeloVox - Vocal Harmony
• QVox Four Voice Pitch Shifter (best so far, but still misses notes and glitches)
but not Tuning reference (ideally adjustable diapason around 440 Hz)

Any app/software that actually compares to hardware pedals?
Or should I just get the real thing?

    Can you elaborate a little on what H-90 functions you aren’t able to achieve with the apps you mentioned?

    I’d imagine the H-90 is running some version of the QVox algorithm itself…

    i've been impressed with yonac's taurus octavizer for fixed intervals.

    it's more of a deep pog than a harmonizer, but worth a mention here imo.

    The POG effect in Bias FX2 is amazing! I use it on my pedalboard when I use AUM.

    Do you use it IAA, or just standalone and direct audio out?

    Great to see you back around, btw!

    Yes it is my Go To for octaver.

    Thanks for asking! I've tried several apps, but they each have limitations:

    Bleass Voices – The algorithm quality isn't great, and it tends to glitch pretty quickly.

    MeloVox - Vocal Harmony – Struggles with instruments. More importantly, it doesn't properly respect the chosen scale, which is a dealbreaker for me.

    Voice Synth Modular – This is more of a vocoder than a true harmonizer, so it's solving a different problem.

    The H-90 has several algorithms, but the ones I rely on most are Diatonic (2 voices with key choice) and Quadravox.
    What makes these special is the combination of accurate scale-following, clean sound quality, and low latency.

    What I'm really looking for in an iOS harmonizer:

    Scale selection (major/minor/modes, etc.)
    Interval control (choose which harmonies: 3rd, 5th, octave, etc.)
    Tuning reference (ideally adjustable diapason around 440 Hz)
    Low latency – I don't need delay/echo in the harmony, just quick response
    Clean algorithm – no artifacts or glitching under normal use

    I use this on both cello and vocals, so it needs to track well on sustained melodic lines, not just discrete vocal phrases.

    Hope that clarifies what I'm after!
