An app being switched off is a strange thing to lose sleep over, and yet people did — years of nights, apparently gone, because the company that made the machine decided the software had reached the end of its life.
The good news is that the panic is misplaced. Your therapy data was never really in the app. It lives on the SD card inside the machine, written there night after night, whether or not anything was reading it.
Getting the record off the card
Take the SD card out of the machine and put it in a computer. Two things read it well.
OSCAR is a free, open-source desktop program and the community standard. It shows detailed figures — events, leak rate, pressure — down to breath-by-breath flow data, which is considerably more than any manufacturer app has ever shown you.
SleepHQ runs in a browser if you would rather not install anything; its free tier holds around thirty days of history, with a paid plan for more. Either way, the full history stays yours, because it is on your card.
What DreamMapper never did
Manufacturer apps are built for reassurance rather than for action. They give you a number and a green tick and, having done so, consider the conversation closed.
What they almost never say is what to change: which adjustment stops the leak that wakes you at four, whether your events cluster when you roll onto your back, whether tonight's problem is the ramp or the humidity or a cushion three months past its useful life. That gap is the reason people quit while holding a phone full of data about why they should not have to.
Where Nightshift picks up
It takes the figures you enter and turns them into the next step in plain words, then tracks whether the step worked. It coaches fit, humidity, exhale relief and mask style; it does not touch your prescribed pressure, and where the answer is clinical it says so.
It works with the numbers from whatever you own — ResMed, Philips, Fisher & Paykel — because you enter them yourself rather than surrendering an account. Your therapy data stays on the device, and it is never sold, brokered, or sent to an insurer on your behalf. Which is, in the end, the whole lesson of DreamMapper: an app can be switched off, and the record should still be yours the morning after.
