SomniCharts vs SleepHQ: Cloud CPAP Reporting Compared

If you're already storing your CPAP data in the cloud — or shopping for a tool that does — SleepHQ is probably the first name you'll hit. It's a well-built, popular platform, and for many ResMed users it's a great fit. This guide compares SleepHQ and SomniCharts honestly: where SleepHQ shines, where it leans toward one ecosystem, and where SomniCharts adds plain-language AI interpretation and broader device support (including Philips DreamStation 2 and Löwenstein prisma).

The short version: both turn your raw SD-card data into readable cloud reports. The differences come down to which machines they read and how much they explain what they show.

What SleepHQ does well

SleepHQ is a cloud-based CPAP reporting platform — you upload your data, it lives online, and you can view detailed charts from any browser without installing desktop software. A few things it genuinely does well:

• Detailed, OSCAR-style charts. SleepHQ surfaces the same depth that desktop tools like OSCAR are known for: AHI, leak rate, pressure, and the underlying flow rate waveform where flat-top breaths and flow limitation hide.
• Community and sharing. This is SleepHQ's standout feature. You can share a link to your data with forum members, support groups, or a clinician, which makes it easy to get a second set of eyes on a tricky night. The CPAP-community culture around it is active and helpful.
• Cloud convenience. No Windows-only desktop install, no fiddling with local files. Your history is in one place and accessible on a phone, tablet, or Chromebook.
• Trend tracking. It keeps your nights over time, which matters because a single night is noise — meaningful patterns only show up over weeks of data.

If you're a ResMed user who wants rich charts plus the ability to share them, SleepHQ delivers.

Where SleepHQ leans (ResMed) and its paid tiers

Two practical things to know before you commit.

It leans toward ResMed. SleepHQ's smoothest, most complete experience is built around ResMed machines (AirSense and AirCurve). ResMed support is the deepest, and most of the community examples you'll see are ResMed data. Support for other brands exists in varying degrees, but the platform's center of gravity is the ResMed ecosystem. If you run a ResMed AirSense 10 or AirSense 11, that's an advantage. If you're on Philips or Löwenstein, it's worth checking exactly what your specific model produces before relying on it.

It has paid tiers. SleepHQ offers a free level plus paid plans (commonly referred to as Pro) that unlock additional features and storage. Tier names, limits, and prices change over time, so confirm the current details on SleepHQ's own pricing page rather than trusting any third-party number — including this one. The takeaway: budget for a subscription if you want the full feature set.

None of this makes SleepHQ a poor choice. It's a strong tool that's clearest about one brand. The question is whether your machine and your need for explanation line up with what it does best.

SomniCharts' differentiators — AI interpretation, multi-vendor

SomniCharts is also a cloud CPAP reporting platform — you upload your SD-card data and view it in any browser. Two things set it apart.

Plain-language AI interpretation

Most tools — SleepHQ and OSCAR included — show you the numbers and charts and leave the interpretation to you (or to whoever you share with). That's fine if you already know what a 95th-percentile pressure means or why a leak spike matters. If you don't, a wall of charts can be intimidating.

SomniCharts layers an AI assistant (SomniDoc) on top of the reporting. It reads your imported data and explains it in plain English automatically — what your AHI is telling you, whether your leak rate is in range, how your pressure numbers compare night to night. It's data education, turning raw metrics into something you can actually act on in conversation with your provider.

One trust-building example: a large mask leak can invalidate or under-report your AHI, because air escaping the mask means the machine can't reliably "see" your breathing. ResMed flags excess leak above roughly 24 L/min at the 95th percentile (note that ResMed reports excess leak while Philips reports total leak — different baselines, so the same number doesn't mean the same thing across brands). Surfacing and explaining that distinction is exactly the kind of context plain-language interpretation adds.

Genuinely multi-vendor

SomniCharts imports and explains data from:

• ResMed (AirSense, AirCurve)
• Philips Respironics — including the DreamStation 2
• Löwenstein prisma

That Philips and Löwenstein coverage is the second big differentiator, and it deserves its own section.

A note on accuracy: device-reported AHI is an estimate. Home machines don't record EEG or arousals, so their AHI differs from a lab-scored study. AASM scoring also allows two hypopnea rules — Rule 1A (a 3% oxygen desaturation or an arousal) and Rule 1B/CMS (a 4% desaturation) — which is one reason your home number and your sleep-study number won't match exactly. Treat trends, not single-night figures, as the signal.

Explicit Philips DS2 and Löwenstein support

This is where the "which machine do you own" question becomes decisive.

Philips DreamStation 2. The DreamStation 2 writes its SD-card data in an encrypted format that OSCAR and most third-party tools cannot read. For a lot of DS2 owners, that's a dead end — they bought a machine, the manufacturer app shows them a thin summary, and the detailed data feels locked away. SomniCharts supports the DreamStation 2 explicitly, so DS2 owners can actually get full cloud reporting from a device that otherwise stonewalls third-party software. (For the why behind the encryption, see Philips DreamStation 2: Why Its Data Is Encrypted.)

Löwenstein prisma. Löwenstein is the under-served brand in the CPAP-data world — far fewer tools read it well. SomniCharts imports Löwenstein prisma data and explains it the same way it handles ResMed and Philips, which matters if you're outside the ResMed-dominant ecosystem. See the Löwenstein Prisma data guide for what your card holds.

For context, here's how the broader landscape stacks up — including tools we're not directly comparing here:

• myAir (ResMed): ResMed-only, shows a 0–100 score weighted heavily toward usage hours, with no event-type, leak, or flow-limitation detail; the formula has never been published, and you can score 100 with an AHI near 4.9.
• DreamMapper (Philips): shut down in January 2026 — former users need a new home for their data.
• OSCAR: free, powerful, desktop-only (no Chromebook), with no auto-scoring or interpretation, and it can't read the encrypted DS2.

One honesty note: SomniCharts does not import Fisher & Paykel SleepStyle data. If you're on an F&P machine, treat that as ecosystem education for now, not a supported import. (More on the Fisher & Paykel data picture here.)

Side-by-side comparison

How to choose

• Pick SleepHQ if you're a ResMed user who values the active community and link-based sharing above automatic interpretation.
• Pick SomniCharts if you want plain-language explanations of your data, or if you own a Philips DreamStation 2 or Löwenstein prisma and need a cloud tool that actually reads it.

Many people genuinely benefit from trying both free tiers and seeing which reports they understand more easily. If you're still weighing options, the OSCAR vs SleepHQ vs SomniCharts support matrix maps exactly which tool reads which machine, and the broader web-based CPAP analysis tools roundup puts the whole category in one place. Whichever you choose, the goal is the same: turn weeks of data into an informed conversation with your sleep clinician.

FAQ

Is SomniCharts a SleepHQ alternative?

Yes. Both are cloud CPAP reporting platforms that turn your SD-card data into browser-based charts. The main differences are that SomniCharts adds automatic plain-language AI interpretation and explicitly supports Philips DreamStation 2 and Löwenstein prisma in addition to ResMed, while SleepHQ's strengths are its ResMed depth and community sharing.

Does SleepHQ support Philips DreamStation 2?

The DreamStation 2 stores its data in an encrypted format that most third-party tools — including OSCAR — cannot read, and brand coverage outside ResMed varies on SleepHQ. SomniCharts supports the DreamStation 2 explicitly. If you own a DS2, confirm current support directly with each tool before subscribing.

Is SleepHQ free?

SleepHQ offers a free level plus paid tiers (commonly called Pro) that unlock more features and storage. Plan names and prices change, so check SleepHQ's own pricing page for the current details.

Which is better for non-ResMed machines?

If you run a Philips (including DreamStation 2) or Löwenstein prisma machine, SomniCharts is built to import and explain that data alongside ResMed. SleepHQ's deepest, smoothest experience is built around the ResMed ecosystem.

Can either tool replace my doctor?

No. Both are data-education tools that help you read and track your therapy over time. Use what you learn to have an informed conversation with your sleep clinician — and never self-adjust prescribed pressure based on a report alone.
