# pocketHb demo

Interactive Gradio Space for [pocketHb](https://github.com/jayanthvee/pocketHb) — open-source replication of the personalization layer from the Mannino et al. PNAS 2025 fingernail-Hb paper.

Upload a few iPhone-style nail photos and (optionally) provide your real bloodwork Hb to see the per-user calibrator fit on the spot.

**Not a medical device.** Research replication only. Read the [model card](https://huggingface.co/bubbaonbubba/pockethb-base) for full disclaimers.
