Show HN: Harp – Offline, Org-Mode Based Personal Health Records Application

[lepisma]

I built Harp because I couldn't keep my own health records in one place without relying on cloud platforms or hospital portals.

Harp is a strictly offline Personal Health Record app that stores everything in plain Org Mode files. You can: 1. Maintain journals of health events 2. Attach reports, prescriptions, scans, any other file as org-mode attachments 3. Search and filter using on-device OCR 4. Export curated takeouts for doctor visits

There is no cloud, no trackers, no ads. You own the files and decide how to sync them (Syncthing, Nextcloud, local filesystem, whatever).

I wanted to support more devices so it’s written in Kotlin Multiplatform. Android is ready, iOS is planned. For desktop, since these are Org files, working with them in Emacs is really easy.

If you care about private health data, I'd love your thoughts.

I have already bought Journelly for iPhone thinking it might be useful for such tracking, but the UI didn't quite fit. But I liked that it had an org-mode backend and no subscription/server part. So going by past data[0] I think you have at least one sure sale if you publish an iPhone version :-)
