Features & Capabilities

O₂ Buddy makes your blood oxygen readings effortless to see, understand, and track - on your iPhone, your Home Screen, and your wrist.

Your Apple Watch already measures your blood oxygen throughout the day and night. O₂ Buddy turns those readings into something you can actually use.

SEE YOUR TRENDS • Switch between 24 hours, 7 days, 30 days, and 90 days with a tap • Every day shows its full range alongside its average, so you see the whole picture - not just the last number • Watch your average rise or fall compared to the period before

DAY VS NIGHT • Compare your daytime readings against your overnight ones, side by side • Wear your watch to sleep and see how your oxygen behaves while you rest

EVERY READING IN CONTEXT • Tap any reading to see where it falls within that day • Compare it against readings taken around the same time on other days • Know instantly whether it's normal, below normal, or low

ON YOUR WRIST • A fast, glanceable Apple Watch app with your recent readings and 7-day trend • Complications in circular, rectangular, corner, and inline styles - including a color-coded gauge ring and a 7-day trend sparkline • Readings sync from your iPhone as soon as they're recorded

ON YOUR HOME SCREEN • A widget for your latest reading • A widget for your 7-day trend

LOW OXYGEN ALERTS • Optional notifications when a reading falls below a threshold you choose

PRIVATE BY DESIGN • Read-only access to Apple Health • Your data stays on your devices - never uploaded, never shared, never sold

Also includes Light, Dark, and Automatic appearance, 12- or 24-hour time, and built-in FAQs and support.

O₂ Buddy is not a medical device and is not intended to diagnose or treat any condition. Blood oxygen measurements are recorded by Apple Watch and stored in the Health app.

User Reviews

Users like the watch-enabled, clean UI for viewing O2 data, and value the convenience features. However, multiple reviews cite reliability and compatibility issues, especially around Health app syncing, timing of updates, and limited watch data visualization. The app fills a gap left by Apple but lacks a robust, independent data pipeline and mature graphing on the watch. Overall, it's a helpful tool when it works, but reliability and device support are common concerns.

Pros

Gives oxygen readings on Apple Watch, letting you check O2 data on your wrist.
Clear, easy-to-read charts on both iPhone and Apple Watch.
Supports watch shortcuts/complications for quick access.
Fills a gap left by Apple with a simple, non-overwhelming interface.
Affordable price compared to other solutions.

Cons

Health data syncing to the Health app is unreliable or missing; some data never shows up.
Reliability/timing issues: readings may appear only after phone notification, updates can lag or fail (including late-night updates).
Device/OS compatibility problems (e.g., SE2 compatibility, iPhone 15+/iOS 26 issues).
On-watch trend graph is missing; current UI shows only a list instead of quick-glance graphs.
Some users feel it's not worth the price or is inconsistent (e.g., ‘Waste of money’).

Recent reviews

This app is easy to use and beneficial for tracking your daily health. It is easy to set up and send notifications of the information to your phone. I like how everything flows and is easy to setup.
