Shaken and stirred
Some people have to get up, some might need a lie-in, but the shrill sound of iOS’s “Old Car Horn” or Samsung’s “Space Bell” can wake everyone within earshot. This simple device, mounted on a soft-touch strap, connects to your phone via Bluetooth and is worn on your wrist at night. Set an alarm via its dedicated app and it’ll gently vibrate when that time rolls around, waking you and (hopefully) nobody else. You can adjust the level of the intensity on a one-to-nine scale; I set a backup alarm while testing it, but was reliably stirred by level 2 or 3. As someone who regularly falls asleep on trains, I also found it handy for rousing me at my stop.
