Is there a completely offline voice changer app for iPhone?

MimicMic is an iPhone App that requires iOS 26 or later. To use it, simply hold the record button to perform a line (up to thirty seconds per take), then release to transform your speech into an anime or game character voice.

The conversion is powered entirely on-device by Apple silicon. Because the processing operates voice-to-voice rather than through text, it preserves your original timing, rhythm, cadence, and dramatic emotion.

Every converted line is automatically saved in your history. You can replay takes, share them directly, or export individual standard WAV files or a complete ZIP package.

All voice models run locally on your iPhone with zero cloud reliance. You can convert audio in Airplane Mode, in remote recording locations, or anywhere without Wi-Fi or cellular service.

Your voice recordings never leave your iPhone, ensuring total creative privacy.

MimicMic also includes an Apple Watch companion app. You can record a line directly on your Apple Watch, and your iPhone will convert the audio and play the character voice back.

MimicMic is not a real-time voice changer: it cannot be used during live phone calls, Discord voice channels, or live streams. It is designed for take-by-take recording where you hold to record and release to transform.

MimicMic is not text-to-speech: there is no text prompt or script generator. You act out the line in your own voice, and MimicMic changes the vocal timbre while preserving your acting.

The app comes with six built-in original character voices ready to use from the moment you install it. You can also create custom voices using a short recording of your own voice or by importing audio files that you have the legal rights to use. Creating custom voices does not consume conversion credits.

MimicMic is free to download on the App Store and includes five free conversions to test the quality and speed on your own device. Once you are ready, a single one-time in-app purchase unlocks unlimited lifetime access. There are no monthly or annual subscriptions.
