On iPhone (iOS 26 or later), WakeGlass alarms use Apple's AlarmKit and ring even in Silent mode and Focus. On Android, WakeGlass alarms ring through Do Not Disturb and appear full screen over the lock screen, even when the app is closed.
Yes. WakeGlass schedules its alarms and timers with AlarmKit, the system alarm Apple added in iOS 26, so they ring with the switch on silent and in every Focus. iOS asks once whether WakeGlass may schedule alarms; if you said no, alarms cannot ring until you allow it in Settings → WakeGlass.
iOS controls the hardware volume; WakeGlass rings at the system alarm level. The screen-brightening and flashlight wake aids work only while WakeGlass is open and the phone unlocked.
Yes. WakeGlass plays on the alarm sound channel and schedules with Android's alarm clock, so Do Not Disturb, which lets alarms through unless you changed that, does not silence it. It opens a full-screen ring screen over the lock screen and rings with the app closed.
Almost always battery saving. Many phones pause background apps, which can delay or silence an alarm. Two settings prevent it: allow exact alarms, and exclude WakeGlass from battery optimization. Both are in the welcome tour, which you can replay from About.
Since version 1.2.19, WakeGlass shows a one-time card with the exact steps on phones known for this, among them Samsung, Xiaomi, Redmi, POCO, Huawei, Honor, OnePlus, Oppo, Realme and Vivo. It stays hidden if WakeGlass is already exempt.
Android WakeGlass sets your alarms again after a restart, an app update or a time change, once you have unlocked the phone for the first time after switching it on.
iPhone AlarmKit keeps the alarms with the system.
