I have an iPhone 11 Pro Max running iOS 26. But since iOS 18, Apple decided to remove the "Time in Bed" feature[1][2]. Is it possible to develop an app that, effectively, "brings back" this feature? It doesn't have to be that accurate. Just a gauge is fine. As a starter I would like to track the time the phone was in Sleep mode (regardless whether the phone is being used). I have a minimal programming background but have not developed an iOS app before so any help would be appreciated. I found out about HealthKit[3] which lets me access (edit?) Health data, but I don't know where to go from there.
