Get set up in
minutes.
Everything you need to install LumAlarm, master every feature, and fix the rare hiccup. Curious about the why? The science lives in the Sleep Library.
Your first gentle alarm
Five minutes tonight, a kinder morning tomorrow. The everyday path is short on purpose.
Install from Google Play
LumAlarm runs on Android 9 and up. Grab it from the Play Store and open it — there's no account to create.
Grant the essentials
The app asks for alarm & notification access (so it can take over the screen at wake time), the camera (for the flashlight ramp), and optionally your location for live weather. Nothing leaves your device beyond that weather lookup.
Set a time and repeat days
Tap +, choose your wake time, and pick the days. That's genuinely all you need — sensible defaults handle the rest.
Pick a sunrise length
Choose how long the light takes to build — 5 minutes for a brisk start, up to 45 for the gentlest possible lift. 20–30 minutes suits most people.
Place your phone & sleep
Set the phone face-up on the nightstand, or face-down with the flashlight on if you'd rather not have a screen by your head. Plug in overnight for total peace of mind.
Make it yours
Every rich option, explained. Tap a topic to open it.
Light: sunrise length, screen & flashlight
Sunrise length sets how long the light takes to climb to full — anywhere from 5 to 45 minutes. A longer ramp is gentler; a shorter one is brisker. You can set it per alarm, so weekdays and weekends can differ.
Two light sources. The screen sunrise paints a living gradient from deep indigo through amber to warm white. The flashlight ramp adds real, room-filling light from the camera flash — useful if the phone is face-down or across the room. Use either or both.
Adapt to room brightness reads the ambient light sensor so the sunrise is never a harsh glare in a pitch-dark room, and still strong enough in a lighter one.
Sound: layers, ramp, fade-in & music handoff
Layered sounds arrive in sequence — curated birdsong eases into chimes, then your alarm tone — so sound builds as gently as the light. You can also bring a custom ringtone from your device.
Volume ramp + max cap. Volume rises slowly from silence and never exceeds the ceiling you set, so it can't blast you awake. Fade-in before wake starts that rise just ahead of your wake time, so sound is already present — never a hard start.
Music after the alarm. Once you dismiss, LumAlarm can hand off to internet radio, a local track, or Spotify to carry the morning on.
Smart motion-based early wake
With smart wake on, LumAlarm watches for movement in a window of up to 30 minutes before your set time. If it senses you stirring — already in light sleep — it begins the sunrise then, catching you at a natural moment instead of pulling you from deep sleep. If you don't stir, it simply wakes you at your set time as usual.
Dismiss challenge & snooze
If you tend to dismiss alarms in your sleep, gate Dismiss behind a quick math or tap challenge — just enough to make sure you're actually awake. Snooze stays forgiving: a soft extra few minutes when you truly need them, with the light easing back up afterwards.
Spoken greeting & live weather
When you dismiss, LumAlarm can speak a short good-morning and read today's live weather. The forecast needs a connection and your location; without one, it still greets you and simply skips the weather. You can turn the greeting, the weather, or both off per alarm.
Wind-down: warm light & auto-dim sunset
The morning, mirrored. Warm light gives you a hand-tuned glow — set the warmth and brightness for reading or relaxing. Sunset mode auto-dims that glow to zero over your chosen length, so the light fades as you fall asleep, showing the remaining time as it goes. A nightly wind-down reminder can nudge you toward bed at a consistent hour.
Multiple alarms, repeats & skip-next
Keep as many alarms as you like, each with its own repeat-day rule and settings. Skip-next turns off just the next occurrence — handy for a one-off lie-in — without deleting the alarm or losing its schedule. A simple toggle enables or disables any alarm entirely.
Accessibility & themes
Accessibility is a core requirement, not an add-on: large touch targets, content descriptions on every control, full screen-reader support, and light and high-contrast themes alongside the default dark. The wake screen keeps its text legible and contrast-safe even as the background brightens.
When it misbehaves
Android is strict about background apps. A few one-time settings keep your alarm rock-solid.
The one thing to set up
An alarm has to run in the background and fire at the exact time you set. Most phones handle this fine, but some — especially Samsung and Xiaomi — aggressively put apps to “sleep” and can silently stop alarms (an alarm that worked for days then suddenly doesn’t is the classic sign). Set this once and you won’t miss a wake:
- Allow exact alarms (Android 12+): Settings → Apps → LumAlarm → “Alarms & reminders” → Allow.
- Unrestricted battery: Settings → Apps → LumAlarm → Battery → “Unrestricted” (don’t optimise).
- Keep notifications on, and never “Force stop” the app — that cancels its scheduled alarms until you reopen it.
The app also has a one-tap Alarm reliability helper (Settings → Alarm reliability) that opens these for you and shows the exact steps for your phone.
Then the per-phone step that really matters — find your manufacturer:
Samsung (One UI)
- Settings → Apps → LumAlarm → Battery → set to Unrestricted.
- Settings → Battery → Background usage limits → remove LumAlarm from Sleeping apps and Deep sleeping apps (and add it to Never sleeping apps).
- Settings → Battery → turn off Put unused apps to sleep / Auto-disable unused apps.
Xiaomi / Redmi / POCO (MIUI / HyperOS)
- Settings → Apps → Manage apps → LumAlarm → turn ON Autostart.
- Same screen → Battery saver → choose No restrictions.
- Open Recents, swipe down on the LumAlarm card and tap the padlock so it isn’t cleared.
OnePlus (OxygenOS)
- Settings → Apps → LumAlarm → Battery → “Don’t optimize” / allow background activity.
- Settings → Battery → Advanced → turn off Sleep standby optimization and Deep optimization.
- Lock LumAlarm in Recents.
Oppo / Realme (ColorOS)
- Settings → Apps → LumAlarm → allow Auto-launch and Run in background.
- Settings → Battery → turn off Sleep standby optimisation.
- Lock LumAlarm in Recents.
Huawei / Honor (EMUI / MagicOS)
- Settings → Apps → LumAlarm → Battery → App launch → switch to Manage manually and enable Auto-launch, Secondary launch and Run in background.
- Settings → Battery → turn off the Power-intensive prompt.
Vivo / iQOO (Funtouch / OriginOS)
- Settings → Battery → High background power consumption → allow LumAlarm.
- Settings → Apps → LumAlarm → turn ON Autostart and allow background activity.
Pixel / Motorola / Nothing (near-stock)
- Settings → Apps → LumAlarm → Battery → Unrestricted.
- Allow exact alarms. These phones are usually reliable once that’s done.
Another phone
Allow LumAlarm to auto-start / run in the background and exclude it from battery optimization in your phone’s battery settings; if your phone has a “protected apps” or “auto-start” list, add LumAlarm to it. For exact, model-specific steps, see dontkillmyapp.com.
My alarm didn't go off
Almost always this is your phone's battery optimisation putting the app to sleep. See Make sure your alarm always fires above for the exact steps for your phone — in short: set Battery → Unrestricted, allow Alarms & reminders, and on Samsung/Xiaomi remove LumAlarm from the “deep sleep / app standby” list. The app's Alarm reliability helper opens these settings for you.
