Hi everyone! I'm Matteo. I built Eyenima as a wellness/educational companion — explicitly NOT a medical device. The Iris Art feature captures the unique texture of your iris with the TrueDepth camera and turns it into a personal portrait (CyberNeon, Topographic, Ultra-Res styles). Vision check-ins use neutral wellness tiers ("Typical / Variable / Atypical / Repeat") — never disease names. Everything stays on the device with FileProtectionType.complete, no analytics, no ads. Free, with optional voluntary tips. Happy to answer technical questions about the TrueDepth pipeline, the on-device CoreML iris segmentation, or the privacy architecture (GDPR art. 9 explicit consent).

Hey PH 👋 Matteo here, solo dev from Italy.

Eyenima started as curiosity: what if you could capture your own iris as a portrait? TrueDepth made it possible to do it well — and to do it entirely on-device. I added a layer of educational visual check-ins around it (acuity, contrast, color, near-point convergence, etc.), framed as wellness, never medical. Result tiers are "Typical / Variable / Atypical / Repeat" — no disease names.

Three things I'm proud of:

• Zero off-device transmission. No cloud, no account, no analytics SDKs.

• Iris Art runs three on-device CoreML stylizations (CyberNeon, Topographic, Ultra-Res).

• Free, with optional voluntary tips. No gating, no paywalls.
