Not surprisingly, there is a ton of alarm clock apps on the App Store. Did you ever wonder how they work under Apple’s strict? Local Notifications Have Limitations Yes, there are, allowing apps to play an alarm sound at a specified time.

But other than that, local notifications are of very limited usefulness to a sophisticated alarm clock app:. A local notification does not wake up the app unless the user interacts with it, giving the app no control when the alarm sounds. Alert sounds have a maximum duration of 30 seconds and there is no way to repeat them automatically. (An app could schedule multiple local notifications in pre-defined time intervals to simulate a repeating alert, though.). Local notifications cannot override the ring/silent switch or the device’s Do Not Disturb setting. Alert sounds must be located in the app bundle. Users cannot specify a song from their music library as their alert.

Apps have no control over the volume of a local notification’s alert sound (for example, to slowly crank up the volume of the alarm). Let’s take the beautifully designed as an example. Rise overcomes all these limitations, so how does it do it?

A could be used to wake up the app, but that would require a server infrastructure and a network connection. Do you want to risk that your alarm clock might stop working when the network goes down? Moreover, that feature was just introduced in iOS 7 and Rise did work on earlier OS versions.

Opt out of Multitasking Rise’s surprising solution is to altogether. What was presumably intended by Apple as a temporary option for apps when is still available: If you do not want your app to run in the background at all, you can explicitly opt out of background by adding the UIApplicationExitsOnSuspend key (with the value YES) to your app’s Info.plist file. When an app opts out, it cycles between the not-running, inactive, and active states and never enters the background or suspended states. You can observe this behavior in Rise when you leave the app and immediately reopen it: it relaunches from scratch, showing the launch image again, rather than just wake up from the background.

Rise.app's Info.plist with the UIApplicationExitsOnSuspend key. Rise takes advantage of a subtle difference between the pre- and post-multitasking environments: unlike apps that support multitasking, which get suspended in the background when the device gets locked, an app that runs in the pre-multitasking compatibility mode keeps running when the user locks the device while the app is in the foreground. All the app has to do is wait for the alarm time and execute its custom code. Keep in mind that this trick only works if users launch the app and keep in the foreground before they go to bed (they can lock the device, though). If the app is not running, it has no choice but to fall back to local notifications with their limited features. So Apple’s own alarm clock app can still do a lot more than any third-party app. How Long Will it Last?

I wonder if (and when) Apple will ever deprecate and eventually remove the ability for apps to opt out of multitasking. Makers of alarm clock app would not like that move. Thanks to for helping me figure this out.
