These two apps disagree about what actually wakes a person up. One says movement. The other says distance. Both are defensible, and which is right depends on how you fail.

Movement against distance

Spin's bet: physical motion is what shifts you out of sleep. Spinning raises your heart rate, disturbs your inner ear and is genuinely hard to do while asleep. There is no snooze button, so there is nothing to negotiate with.

Mornio's bet: location is what stops you going back. You can spin beside your bed and then lie straight back down, because you never left. Requiring a scan of a code that lives in the bathroom or kitchen means the alarm ends somewhere else entirely, with a door crossed and a light on.

The honest read is that spinning is probably better at the moment of waking, and distance is better at the ten minutes afterwards. If your problem is not waking at all, spinning may suit you. If your problem is waking, dealing with the alarm and relapsing, distance plus a follow-up check addresses that more directly.

Where Spin is better

Reach, price and pure physicality

  • iOS 13 and later, so it installs on iPhones that Mornio cannot support at all.
  • Spinning needs no setup. There is no code to register, nothing to print, nothing to replace when the packaging runs out.
  • Nothing to lose or misplace. Mornio's mission depends on a physical item still being where you left it; Spin's does not.
  • A one-off purchase option at $7.99 for Super Sleeper, rather than a recurring subscription.
  • It also has no snooze button, so on that specific measure the two apps are equal.

Where Mornio is better

Distance, the follow-up and privacy

  • It moves you out of the room. Spinning next to the bed leaves you one step from lying down again.
  • It checks again minutes later and restarts protection if you do not respond. Spin's listing does not describe anything after dismissal.
  • No advertising and no tracking declaration. Spin's privacy label lists Location, Identifiers, Usage Data and Diagnostics used to track you, with third-party advertising among the stated purposes, and precise location linked to you.
  • 6.9 MB against 214 MB.
  • Spinning is not for everyone. If you have vertigo, an inner-ear condition, are pregnant, or share a small bedroom, it may simply not be practical or safe.
