TL;DR

  • Our APK teardown found that the latest OHealth app update includes steps for setting up pairing with an Apple Watch.
  • Code strings detail syncing calls, messages, and health data via OHealth.
  • A new “Cardless entry” feature also appears, potentially letting your OnePlus watch act as an NFC door key.

We already knew that the OxygenOS 16 update would be bringing Apple Watch connectivity to the OnePlus ecosystem through the OHealth app. Now, a teardown of the latest OHealth release gives us a better look at how this cross-platform pairing might actually work. Beyond that, it also hides a separate feature that could turn your OnePlus watch into an NFC access card.

According to strings and screenshots we spotted in version 4.40.7_6a8017d_251002 of the app, OnePlus seems to be preparing a full pairing setup flow for Apple Watch users. The strings reference syncing incoming calls, messages, and notifications from your phone to the watch, as well as transferring workout data and health stats to OHealth. You’re prompted to “Install app on Apple Watch” and scan a pairing code displayed on the watch’s screen, suggesting a fairly direct pairing process.
