Doesn't pull in sleep data from other apps – SleepHealth Review

Despite this being one of the main benefits of ResearchKit, and despite the fact that it asks for access to sleep data from Health, there's no evidence that this app pulls in sleep data written to Health from other apps (something that I assume many folks with sleep apnea do). Instead it asks you how many hours you slept and how many times you woke up, which is a way more unreliable measure than motion data from a watch app like Sleep++ or Sleep Cycle.
