Name: Sleep Alarm
Author: bustrama

Set how long you want to sleep. Sleep Alarm then waits until it detects that
you have actually fallen asleep, and only starts counting from that moment.

Go to bed at 23:00, take 40 minutes to drop off, and an 8-hour alarm wakes
you at 07:40 — not 07:00.

In the last 30 minutes before your target it watches for a light-sleep
moment and wakes you then, so you are less likely to be pulled out of deep
sleep.

HOW TO USE
1. Open the app when you get into bed.
2. UP / DOWN to set how long you want to sleep. START to begin.
3. Leave the app open and go to sleep. Back out of it in the morning.

Press MENU at any time to preview the alarm, so you know what it sounds
like before you trust a night to it.

HOW IT WAKES YOU
Vibration, escalating over the first 90 seconds. On fēnix it also uses the
beeper and holds the LED flashlight on at low brightness. It keeps going
until you dismiss it.

IMPORTANT — PLEASE READ
- The app must stay open on screen all night. Connect IQ does not let a
  background app use the vibration motor, so there is no way around this.
- Vibration must be enabled in your watch's system settings, and Do Not
  Disturb must be off. The app warns you when you start it if either is
  wrong. Unlike Garmin's built-in alarms, a Connect IQ app cannot override
  these.
- Sleep detection uses wrist movement and heart rate. It is an estimate, not
  a sleep lab, and it tends to think you fell asleep slightly earlier than
  you did. Compare its result against Garmin Connect for a few nights and
  use the "Onset correction" setting to adjust it.
- Running any app all night affects the watch's own overnight metrics, and
  it uses battery.
- This is not a medical device and must not be relied on for anything
  safety-critical.
