O2 Buddy: Blood Oxygen SpO2

Version 1.5 is the biggest update yet - a whole new way to see your blood oxygen over time! TRENDS ON THE MAIN SCREEN The chart at the top has been rebuilt. Switch between 24 hours, 7 days, 30 days, and 90 days, and see each day's full range along with its average. O₂ Buddy remembers whichever range you used last. NEW: DAY VS NIGHT Tap the moon to compare your daytime readings against your overnight ones. If you wear your watch to sleep, try this one first. RICHER READING DETAILS Tap any reading to see where it fell that day, how it compares to readings taken around the same time on other days, and whether it's normal, below normal, or low. NEW TREND WIDGET A new Home Screen widget shows your 7-day trend at a glance, in small and medium sizes. NEW WATCH COMPLICATIONS • A color-coded gauge ring for circular slots • A 7-day trend sparkline for rectangular slots • Older readings now dim, so you always know when you're looking at stale data FASTER, MORE RELIABLE SYNC New readings reach your watch and complications faster, and complication updates now keep working reliably all day long. A FRESH LOOK Onboarding has been redesigned, and you can now set the app to Light, Dark, or Automatic in Settings. Plus a tip jar for anyone who'd like to support development - entirely optional, and it unlocks nothing. Thanks for using O₂ Buddy!
