Independent iOS developer. I build privacy-first iPhone apps that run entirely on your device — no accounts, no servers, and nothing uploaded.

Apps

• 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.

• 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 three 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.
