Vocal Tune PRO is a real-time pitch correction effect. Use it as Audio Unit in your favourite DAW or standalone to auto tune your vocals or other monophonic audio. After selecting the right key and scale, set the retune amount and retune speed to adjust between a natural effect or a more processed/robotic effect as can be heard in modern productions. To bring some life back to heavily auto tuned melodies, you can add artificial vibrato with settings for the vibrato depth, rate, time between the start of a note and the onset of vibrato and the time it takes for the vibrato to reach full depth. Vocal Tune PRO can be used both as an Audio Unit (AUv3) plug-in inside a host app such as Audio Evolution Mobile Studio, Auria Pro, Cubasis, etc. (given that it supports AU Music Effects (audio effects + MIDI). It can also be run in standalone mode, correcting the input (mic) in realtime. To avoid a feedback loop in standalone mode, using headphones or an audio interface is required. Also have a look at the vocal pitch and time editor 'Vocal Tune Studio' inside our DAW, Audio Evolution Mobile Studio!

The clearest difference is in-app purchases: Voice Synth at none against Vocal Tune PRO's 2. Voice Synth also leads on ratings volume (335 vs 25) and chart position (#153 vs unranked). Vocal Tune PRO's advantage is price ($7.99 vs $8.99) and iOS requirement (11.0 vs 16.6). On rating, review sentiment, update cadence and ads there is nothing between them.
