Independent iOS developer. I build privacy-first iPhone apps that do their work on your device — no accounts, and your photos, music and voice never leave your iPhone unless you choose to share them.

Mimic: Voice Clone & Changer
Mimic is a voice cloning and real-time voice changing app for iPhone. It clones a voice from a short sample and lets you speak in that voice live through the speaker or AirPods — entirely on device, with no account and nothing sent to a server.

Verdict: AI Image Detector
Verdict is an AI image and video detector for iPhone that tells you whether a photo or video is real or AI-generated. It runs its checks on device and returns a 0–100 score with the evidence behind it. Nothing is uploaded.

Refract: Music Visualizer
Refract turns a song, or the sound from a video you made, and a few photographs into a video that moves with the music. It finds the beats, the tempo and the sections on your iPhone, then choreographs the whole edit — or hands you a multi-track timeline to build it yourself. Nothing is uploaded.

Postcard: Voice Journal
Postcard is a private voice journal for iPhone and Apple Watch that you can ask questions. Speak a thought and it transcribes it, remembers it, and answers questions about your own moments — all on device.
Approach
All four apps share the same constraint: the processing happens on the iPhone itself. Voice samples, photos, videos and journal entries never leave the device, because none of these apps have a backend to send them to. There are no accounts, no analytics and no third-party tracking SDKs.
