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.

Getting started

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.

wb_twilightLight: sunrise length, screen & flashlightexpand_more

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.

graphic_eqSound: layers, ramp, fade-in & music handoffexpand_more

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.

sensorsSmart motion-based early wakeexpand_more

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.

verified_userDismiss challenge & snoozeexpand_more

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.

record_voice_overSpoken greeting & live weatherexpand_more

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.

bedtimeWind-down: warm light & auto-dim sunsetexpand_more

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.

alarmMultiple alarms, repeats & skip-nextexpand_more

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_newAccessibility & themesexpand_more

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.

Troubleshooting

When it misbehaves

Android is strict about background apps. A few one-time settings keep your alarm rock-solid.

alarm_offMy alarm didn't go offexpand_more

Almost always this is your phone's battery optimisation putting the app to sleep. In Settings → Apps → LumAlarm → Battery, set it to Unrestricted (or exclude it from optimisation / Doze). On Samsung, Xiaomi, OnePlus and similar, also turn off any "deep sleep" or "app standby" for LumAlarm and lock it in Recents. Confirm Alarms & reminders permission is granted under the app's permissions.

flashlight_offThe flashlight won't rampexpand_more
Check that the Camera permission is granted — the flashlight is the camera's flash, so LumAlarm needs camera access to control it. Also make sure no other app (or a quick-settings torch tile) is holding the flash open. If the flash is in use elsewhere, close that app and try a preview from the alarm editor.
brightness_lowThe sunrise is too bright (or too dim)expand_more
Turn on Adapt to room brightness so the ramp scales to your room's darkness. If you still find it strong, shorten the peak by lowering the maximum, or rely more on the flashlight with the phone face-down. For a brighter result in a light room, switch adaptation off and let it run at full.
cloud_offThe greeting skips the weatherexpand_more
The live forecast needs both an internet connection and Location permission. If either is missing, LumAlarm still speaks the greeting and simply leaves out the weather. Grant location (even "while using the app" is enough at wake time) and check your connection to restore it.
music_offMusic handoff to Spotify isn't playingexpand_more
Make sure the Spotify app is installed and you're signed in. The handoff opens Spotify to start your chosen track or playlist; for reliable background playback, Spotify's own controls and account need to be active. As an alternative, hand off to a local track or internet radio, which don't depend on another app's login.
FAQ

Quick answers

Does the screen stay on all night and drain my battery?expand_more
No. The sunrise only runs during the wake window you choose — anywhere from 5 to 45 minutes — and the screen stays dark the rest of the night. A typical ramp uses very little power; plug in overnight if you'd like total peace of mind.
Does the flashlight really make a difference?expand_more
Yes — the camera flash adds real, room-filling light alongside the screen, which matters if your phone is face-down or across the room. Use the screen, the flashlight, or both, and let LumAlarm adapt the intensity to how dark the room is.
Will it still wake me if the phone is locked?expand_more
Always. LumAlarm runs as a proper alarm and takes over the screen at wake time even when locked, with the same large Snooze and Dismiss controls — and an optional math or tap challenge if you tend to dismiss in your sleep.
Can I wake to Spotify or my own music?expand_more
You can layer curated sounds — birdsong into chimes into your alarm — and bring custom ringtones from your device. After the alarm, hand off to internet radio, a local track, or Spotify to carry the morning on.
Does it work offline? Are there ads?expand_more
The alarm, sunrise, and sounds work fully offline; only the spoken greeting's live weather needs a connection — without one, it greets you and simply skips the forecast. And no, there are no ads. Interruptions would rather defeat the point.
Is it accessible, and what permissions does it need?expand_more
Accessibility is a core requirement: large touch targets, content descriptions on every control, full screen-reader support, and light and high-contrast themes. It asks for the camera (flashlight), alarm and notification access, and optionally your location for local weather — nothing leaves your device beyond that weather lookup.
How much does LumAlarm cost?expand_more
LumAlarm is a one-time purchase with no ads and no subscription — every feature described here is included. Updates are free, and nothing is locked behind recurring fees.
Which devices does it support?expand_more
LumAlarm runs on Android 9 and newer, phones and tablets. An iOS version is in the works — there's an "App Store, coming soon" badge on the home page. The flashlight ramp needs a device with a camera flash; everything else works without one.
