One data note, because it decides more of this choice than the spec sheet does. Machines differ in what they record and how you get it out. Some write a full night of detailed data to a card that you own; some report a reduced summary to an app and nothing else; some do both but only if the card is actually in the slot. If you ever want to answer a question more specific than "was my AHI under 5", that difference matters more than the model number. So the practical question to ask before buying anything: does this machine take a card, and does it write detailed data to it? If the answer is no, every future conversation about your own therapy is limited to what a summary screen chooses to show you. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

The comparison question this article gets asked most often, answered from the data side rather than the sales side. Between a machine generation and its successor, the therapy algorithms are usually close relatives and the detailed data written to the card is broadly the same shape — so if you already know how to read one, you are not starting again. What tends to change is everything around it: the screen, the setup flow, the humidifier and tube fittings, the cellular reporting, and sometimes whether a card slot is present or populated at all. Two practical notes for anyone buying, new or used: Check that the card slot is there and that a card is in it. Some units ship with the slot empty, and a machine that is not writing to a card is not keeping the detailed record you will want later. A card that has never been in the machine holds nothing retrospectively. On a used machine, check the hours counter and the current settings before anything else. The hours tell you what you actually bought; the settings tell you what somebody else was prescribed, which is not what you were. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

The practical difference between the two routes, since this is the article people land on when they ask what the cloud actually gets. The card holds the detailed night: flow, pressure over time, individual events with their timestamps, leak as a trace rather than a number. It is what makes questions like "when in the night does this happen" answerable. The cloud summary holds the headline: hours, an event index, a leak figure, a pressure figure. Enough to confirm you used it and roughly how it went; not enough to work out why a night was bad. Which is why "my app says my AHI was 4.2" and "I looked at my data" are different sentences. If the only record you keep is the summary, the detailed night is gone once the card is overwritten — cards do get reused, and the oldest detail is what goes first.
