After your first night of sleep with Smartbuds, the Trends page in the app will begin to fill with data. Here’s a quick guide to what those numbers mean:
Metric | What It Means |
Slow wave count | Slow waves are deep pulses of brain activity that mark your most restorative sleep. A higher slow wave count reflects better rest and recovery. |
Slow wave time | The minutes you spend in deep, restorative sleep. More time here supports recovery for body and brain. |
Sleep efficiency | The share of time in bed you’re actually asleep. Higher efficiency means less tossing and more consolidated rest. |
Drift-off time | How long it takes you to fall asleep after starting a session. Shorter times suggest healthy sleep; longer times can reflect stress or irregular habits. |
Total wakes | The number of times you wake during the night. Fewer wake-ups mean less fragmented sleep and deeper recovery. |
Total sleep | Your overall hours asleep. Needs vary by person, but enough rest is key to energy, focus, and performance. |
