Mobile, On-Device CPAP Data Analyzer With OSCAR-Grade Detail For Apnea Patients Who Refuse A Desktop Or A Cloud Subscription

mobile app real project •• multiple requests

OSCAR is the free gold standard for reading raw CPAP SD-card data, but it only runs on desktop operating systems and there is no mobile build. Patients who want OSCAR-level event detail on a phone are stuck between SleepHQ's paid web/cloud service and the shallow vendor apps (myAir, DreamMapper). The opportunity is an app that reads the CPAP SD card directly on the phone and renders flow-rate, pressure, and event graphs locally, with no desktop and no cloud upload.

builder note

The hard part isn't the charts, it's parsing every vendor's proprietary SD-card format (ResMed, Philips, React Health). OSCAR's parsers are the real moat; porting that parsing logic, not redrawing graphs, is the actual project.

OSCAR-grade analysis is free but chained to a desktop, and the only mobile route is a paid cloud upload. Nobody offers detailed CPAP analysis that stays on the phone and off a server.

OSCAR (Open Source CPAP Analysis Reporter) Free and extremely detailed, but desktop-only (Windows/Mac/Linux/Chromebook/RasPiOS); needs a computer and an SD-card reader, so there is no way to check therapy data on a phone.

SleepHQ Gives phone access to detailed data, but it is a paid cloud service: you upload your SD-card data to their servers, and the wireless-capture option is still in progress.

ResMed myAir / Philips DreamMapper Vendor apps show a compliance score and basic nightly stats but hide the flow-rate and event-level detail patients use to actually troubleshoot pressure and leaks.
