The first hundred nights, on the record.
Almost nobody quits CPAP because the therapy failed. They quit in the first weeks, over a mask that leaks at four in the morning, a pressure that feels like too much to breathe against, and air so dry it wakes them anyway — and nobody is keeping the record while they get through it.
Nightshift is that record. It asks ten seconds in the morning — hours on, and one tag: full night, leaked, took off, insomnia — and turns your nights into trends and insights you can actually see. Your adjustment period, written down, for as long as it takes.
§ I — The program
What Nightshift keeps for you through the adjustment period, what it refuses to touch, and the price in plain print.
The check-in is deliberately small: how many hours the mask was on, and one honest tag — full night, leaked, took it off, or insomnia. Add a note if the night deserves one. That is the entire ask, because an app that demands a questionnaire at 6am is an app you stop opening by week two.
Log it from the app, the widget, your watch, or by asking Siri. One optional reminder if mornings get away from you — or none.
The check-inOne bad night after a cold or a late glass of wine is a bad night. A slow drift over a fortnight is a signal — and the only way to tell the difference is a record. Nightshift charts your last seven days, and the insights and calendar screens show the longer shape: how often the mask stayed on all night, which tag keeps recurring, whether the leaked nights are clustering.
It can also read your sleep data from Apple Health, if you choose to allow it, so hours in bed sit next to hours on the mask. The reading is optional and one-way — Nightshift writes nothing back.
The trendMost insurers keep covering the machine only if you use it at least four hours a night on most nights inside an early window. Nobody explains this well, and finding out late is how people lose equipment they were slowly getting used to.
Our free web compliance calculator does that arithmetic in the open, on this site, from numbers you type in. And your nightly log in the app is the record you bring to the conversation — export it to CSV any time and hand it to whoever you choose.
The windowIt is your record, not ours. Your nights sync only to your own private iCloud, under your Apple ID — we run no server that can read them, and nothing is sent to an insurer, a supplier, or an employer on your behalf.
Philips retiring DreamMapper in 2026 is the argument in one line: an app can be switched off, and the numbers should still be yours when it is. CSV export exists so that they always are.
The recordNightshift is free to download. The nightly log, the streak and the last thirty days cost nothing and always will. Nightshift Plus is $2.99 a month, or $19.99 a year, and unlocks the 90-day insight window and the supply tracker. Both plans start with a 7-day free trial, both auto-renew until you cancel, and cancelling is one switch in your App Store settings. The trial is a standard Apple introductory offer — it becomes the subscription when it ends, and this page says so in plain words.
There is no tier holding your own nights behind it. Purchases go through the App Store, so refunds do too: Apple handles them at reportaproblem.apple.com.
Your therapy data syncs only to your own private iCloud. No ads — your sleep is not an ad slot. We will not sell or broker what your nights say about you, and we will not use it to train anything.
The house's wordNightshift does not make the mask pleasant. It keeps the adjustment period on the record instead of in the fog, for the hundred nights that decide whether the machine ends up beside the bed or in a closet.
Standing prohibitions
Five things Nightshift will not do, held as terms of the program rather than as a roadmap that can quietly change.
§ II — The price
What it costs, what the trial does, and how to leave.
$2.99
Nightshift is free to download: nightly logging, the streak, the last thirty days and CSV export cost nothing. Nightshift Plus — the 90-day insight window and the supply tracker — is $2.99 a month or $19.99 a year, after a 7-day free trial. Both plans auto-renew until you cancel, and you can cancel anytime in your App Store settings. Purchases and refunds are handled by Apple through the App Store, and there are no ads at any price.
The terms
§ III — Questions
The questions new CPAP users actually send in the weeks when they are deciding whether to keep going.
The manufacturer app tells you what the machine saw. Nightshift keeps what the machine cannot: how the night actually went, in your own words and tags — full night, leaked, took it off, insomnia — charted over weeks so the pattern is visible. It works alongside any machine because you keep the log yourself. If you want the deep raw data as well, OSCAR is free and excellent on a desktop, and the two are not in competition.
It will show you the pattern — how often the leaked tag recurs and whether it is getting better or worse — which is the record a fitting appointment or a mask swap should start from. The fixing itself belongs to you and your clinic; the CPAP guide on this site covers the common causes in the open, free, no app required.
No. Your nights sync only to your own private iCloud, and Nightshift sends nothing to anyone on your behalf — not an insurer, not a supply company, not a workplace. If you want your clinician to see the adjustment period, you export the CSV and hand it over yourself.
Never. Pressure is prescribed, and Nightshift will not touch it — that dial belongs to your sleep clinician. Nightshift is a log and a trend, not medical advice, diagnosis, or treatment, and it is not an FDA-cleared device. What it gives your appointment is the written record of how the weeks actually went.
Nothing, for the part most people use: logging a night, the streak, the last thirty days and CSV export are free. Nightshift Plus — the 90-day insight window and the supply tracker — is $2.99 a month or $19.99 a year, after a 7-day free trial. The trial becomes the subscription when it ends, it auto-renews until you cancel, and cancelling is one switch in App Store settings. Refunds for App Store purchases are handled by Apple at reportaproblem.apple.com. There are no ads at any price.
Three weeks in is exactly who this is for. The early weeks are when most people stop, and almost always over things with a fix rather than because the therapy was wrong for them. Nightshift will not make you love the mask. It keeps the record through the stretch where the machine is still an imposition and not yet a habit.
