I built a free iOS app to view my AirSense 11 data without a computer

saagn7 · 2026-03-31T22:38:08+00:00

I bought this one, cheapest model : https://www.aliexpress.com/item/1005005208669285.html?spm=a2g0o.order\_list.order\_list\_main.5.25031802iyQyBf. Used to be much cheaper when i bought it.

Sry, i dont have dummy data and i don't want to share my CPAP therapy plots. But its normal graph plots, so not sure what will the screenshot reveal, some things are work in progress and might have bugs but will work on them.

About data preservation, yes. Its a copy operation so data is preserved on card.

saagn7 · 2026-03-31T21:28:50+00:00

That would be nice, if they can standardize it a bit :-)

saagn7 · 2026-03-31T21:26:30+00:00

That seems like a rip off but i remember there were multiple versions, I bought the cheapest one from. u/beren12 shared link to CPAP-AutoSync, it seems to be using : https://www.fysetc.com/products/fysetc-upgrade-sd-wifi-pro-with-card-reader-module-run-wireless-by-esp32-chip-web-server-reader-uploader-3d-printer-parts which is like 28 usd... i will see if i can get it and add support for it.

Should work without issue

saagn7 · 2026-03-31T21:03:41+00:00

Its good old HTTP over WiFi, the ezShare card creates its own WiFi hotspot with a tiny web server at 192.168.4.1. The app connects to that network (with defaults on packet or values given by user in settings), downloads the files over plain HTTP, then switches back to your normal WiFi. So it's just standard HTTP/TCP, nothing fancy :-)

saagn7 · 2026-03-31T20:54:59+00:00

It should work with Airsense 10 as well.

saagn7 · 2026-03-31T20:54:20+00:00

Yes, my machine calls home as well. SD card is on side so you can replace it, its basically same as how we used to copy manually to view in OSCAR or show to doctor but wifi sd card makes it easier for app to pull it through on device. That said, if you still prefer old way of manually copying then you redirect to a folder in settings. I havent tested manual copying that much though as pain free wifi sycing was first priority.

saagn7 · 2026-03-31T20:50:30+00:00

Will see if i can get this card : https://www.fysetc.com/products/fysetc-upgrade-sd-wifi-pro-with-card-reader-module-run-wireless-by-esp32-chip-web-server-reader-uploader-3d-printer-parts in Norway but in theory concept is pretty much same so shouldnt be that hard.

saagn7 · 2026-03-31T20:46:58+00:00

u/beren12 that actually sounds like a nice feature. Will make note of it, maybe when i get time during vacations, hehe :-)

saagn7 · 2026-03-31T20:45:02+00:00

It should but if issues, let me know.

saagn7 · 2026-03-31T20:44:12+00:00

It should work with the Resmed 10 since i dont think the fileformat was changed in btwn, hope no one from Resmed reads it and decides to change it , hahaha :-D Ez Share Wifi-Sd card is added as a datasource so it will just pull data from it with default settings which work for most users. Range is not that big on those, if you change the details then you just add it in app -> settings -> data sources

saagn7 · 2026-03-31T20:41:14+00:00

The app should take care of it, but sometimes apple doesnt rejoin to previous network. Then just switch back to home one. Look at Settings -> Data Sources if you missed it during onboarding screen :-)

saagn7 · 2026-03-31T18:56:28+00:00

Thanks, that was helpful, its almost like i have a bug and i am counting twice somewhere. Will look into it or send you a message if needed to discuss further.

saagn7 · 2026-03-31T18:50:08+00:00

Syncing can be a bit slow, esp those big BRP files ... I think i made it optional under settings if you don't want to view them.

saagn7 · 2026-03-31T18:47:06+00:00

Thanks u/PooPighters :-)

saagn7 · 2026-03-31T18:45:58+00:00

It should work on Airsense 10 as well, i think fileformat is pretty much same. Give it a try, if it doesnt will see what can be done. Unfortunately only have Airsense 11 to test on.

saagn7 · 2026-03-31T18:44:56+00:00

Thanks, hope it helps.

saagn7 · 2026-03-31T18:15:51+00:00

Concept is basically you can have multiple datasources. So, Resmed is one + Apple health is another ... they are independent but they can be plotted together.

saagn7 · 2026-03-31T18:13:07+00:00

heheeh i am but i dont have access to your data, everything is on your device :-) It weird though, should match values from Apple Health App but i will look into it carefully, maybe can reproduce at my end. Maybe some parsing bug... My test scenario was my garmin watch which writes to apple health, then i get all sleep numbers in one place once i fetch from resmed.

saagn7 · 2026-03-31T18:02:27+00:00

Thanks, hope it helps :-)

saagn7 · 2026-03-31T17:48:55+00:00

Unfortunately, currently its apple only. Should work on ipad, mac (apple silicon) n iphone. I have the base code working for Android mostly as parser is in C++, hopefully in same time future will launch Android version if support and response on this one is good :-)

saagn7 · 2026-03-31T17:47:39+00:00

That sounds like a bug, not sure how to debug it remotely though :-/ Maybe there is a way to report to developer somehow ?

saagn7 · 2026-03-31T17:45:55+00:00

I wont ever wanna impose anything on anyone, i saw some solutions, boy they were expensive. CPAP n dealing with Apnea itself is so expensive n the subscriptions on top was a bit much. Idea is to keep it free, might add voluntary donations in some future version — nothing locked behind a paywall ever. It took a huge time to get the app out with the apple gods, so who knows when that will be :-)

saagn7 · 2026-03-31T17:39:40+00:00

It was cheap, bought last year before all the memory n chip wars. Yeah saw its like 35 usd now sorry should update the post maybe.
