We strive to create high quality software with zero defects, but sometimes bugs do slip through, or problems with particular heart rate sensors are identified. Known issues will be listed on this page.
Heart Graph v4.4.1
- A bug in WatchOS 3 means that the app can crash on, or shortly after launch. Apple have accepted that there is a bug but there is currently no timeline for a fix. If you experience this issue, please relaunch the app.
- A bug in WatchOS 3 can occasionally the Watch app to crash sporadically, especially during very long sessions. Apple have accepted that there is a bug but it looks like the fix will only be available in WatchOS 4. Note that if you do experience this issue, all data recorded prior to the crash will be automatically recovered next time you start Heart Graph on your Watch.
- Occasionally the Heart Graph Apple Watch app fails to install fully on the Watch, especially on WatchOS 2.x. This is nothing to do with Heart Graph, but is due to issues with Apple’s “Watch” app. There is unfortunately nothing specific we can change to improve things, but you may find this Apple Support Page useful, or alternatively an internet search about third party Watch app installation problems will provide other suggestions.
