Blue Blood
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.
Doesn’t list which watches it works with.
I have a SE2 and an iPhone13. The app says it works with the iPhone, but does not say that it doesn’t work with the SE2 watch.
Response from developer
Sorry about that. The SE2 doesn’t have the blood oxygen sensor. Sadly Apple doesn’t let me reject watches. You may still be able to request a refund from Apple.
Thank you
Just helped someone setup their first Apple Watch. They are 79. You made my day. I don’t own a watch, I bought the app to show my appreciation.
O2 Buddy: Used to be more useful
I really miss the old on‑watch graph view. The current list of readings is much less useful at a glance, and only showing yesterday’s average makes today’s data feel incomplete. The mini trend graph on the watch was what made O2 Buddy stand out—please consider bringing a simple graph view back for recent readings and today’s evolving average.

So sorry you feel that way. Did you have an issue with the app?
