I can’t figure out how to have this O2 Buddy Complication trigger the reading to occur. Thank you. -- Still Willing, 2025-10-13 ### ***** "Excellent app" Just what I was looking for. Well done Sir. I created a shortcut and mapped it to my Apple Watch action button so I did not have to use one of the complications on the watch face. -- 1ab12, 2025-09-28 ### *---- "Update Needed ?" I have an iPhone 15+ with IOS 26 Final release. App Won’t get past the check Settings page. No info sent to Health app. Only info from February 2024!🤷🏻‍♂️ -- Fullknight, 2025-09-24 ### ***** "Perfect" Awesome app for those who want to see O2 data and not get overwhelmed -- Juan.VC, 2025-09-23 ### ***** "Finally! O2 on my wrist!" Great app. Gives me back O2 readings on my wrist. Well done! -- Tom78D, 2025-09-14 ### ***** "Great app!" This app fills the big void left by Apple. Nice and easy to read interface. Highly recommended! -- Jeff griffith, 2025-09-13 ### ***** "Praise for O2 Buddy" I am a physician and want to offer my sincere praise for this update. Allowing people who suffer issues in which their O2 sat. abruptly drops can be lifesaving, such as near drowning, blood clots to the lung, acute heart failure, pneumonia, severe COVIS 19, exacerbation of chronic lung disease, severe sleep apnea and altitude sickness. I am especially pleased that the author of this program only charges $0.99 for this app, which makes it affordable for almost everyone. Again, my sincere congratulations for this noble and worthy achievement. -- Participant2025, 2025-09-12 ### ***** "Great job!!" Short and sweet, clear chart showing your readings on both your phone and watch. Nice to finally be able to utilize this feature of the watch. Hope you keep updating and adding features. -- cejmcq, 2025-09-09 ### ***** "Amazing" Truly awesome idea to create an app that allows users to view their blood oxygen levels again on your Apple Watch!!! -- Mhopman31, 2025-09-07 [View all O₂ Buddy reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## O₂ Buddy Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | Malaysia | Health Fitness | #1 | | Top Paid | United States | Health Fitness | #3 | | Top Paid | Netherlands | Health Fitness | #4 | | Top Paid | Philippines | Health Fitness | #4 | | Top Paid | Belgium | Health Fitness | #4 | | Top Paid | Romania | Health Fitness | #5 | | Top Paid | India | Health Fitness | #9 | | Top Paid | Türkiye | Health Fitness | #10 | | Top Paid | Canada | Health Fitness | #10 | | Top Paid | Mexico | Health Fitness | #10 | | Top Paid | Japan | Health Fitness | #11 | | Top Paid | United Kingdom | Health Fitness | #12 | | Top Paid | Norway | Health Fitness | #12 | | Top Paid | Finland | Health Fitness | #14 | | Top Paid | Brazil | Health Fitness | #25 | | Top Paid | Malaysia | Overall | #25 | | Top Paid | Netherlands | Overall | #30 | | Top Paid | United States | Overall | #32 | | Top Paid | Australia | Health Fitness | #36 | | Top Paid | Philippines | Overall | #43 | | Top Paid | Algeria | Health Fitness | #44 | | Top Paid | Belgium | Overall | #50 | | Top Paid | Canada | Overall | #112 | | Top Paid | India | Overall | #127 | | Top Paid | Dominican Republic | Health Fitness | #141 | | Top Paid | Egypt | Health Fitness | #143 | | Top Paid | Norway | Overall | #144 | | Top Paid | Romania | Overall | #153 | | Top Paid | Finland | Overall | #166 | | Top Paid | Mexico | Overall | #170 | | Top Paid | Nigeria | Health Fitness | #177 | | Top Paid | Türkiye | Overall | #188 | | Top Paid | Greece | Health Fitness | #231 | | Top Paid | Argentina | Health Fitness | #233 | ## Apps Similar to O₂ Buddy -
