Quick answer

Setting up a sunrise alarm on Android with Gently takes about 5 min. You install the app, set your target wake time, choose a ramp duration that fits how deeply you sleep, position your phone so the flashlight faces toward you, and pick a calm starting sound. The first morning is your test. Adjust from there.

What you need before you start

Gently installed from the Google Play Store
Your phone charged overnight (the flashlight uses battery)
A sense of how deeply you typically sleep (light sleeper or heavy sleeper)
Your usual wake time

Step 1: Install Gently and open the alarm screen

Download and install Gently from the Google Play Store. Open the app and navigate to the alarm creation screen.

You will see fields for wake time, ramp duration, and sound. Start here before touching anything else.

Grant the permissions the app requests. Gently needs access to your alarm system and flashlight. Without these, it cannot function properly. The permissions are shown with explanations in the app.

Step 2: Set your target wake time

Set the time you actually need to be awake, not the time you plan to lie in bed ignoring the alarm. Be honest with yourself here.

If you have been struggling to wake up at 07:00, set the alarm for 07:00 and configure the ramp to start earlier. Do not set the alarm for 06:30 hoping the gradual approach will make 07:00 feel better. The target time is the hard stop.

Step 3: Choose your ramp duration

Ramp duration is how many minutes before your wake time the alarm begins ramping up. This is the most important setting for getting the gradual effect right.

Use these as a starting guide:

Light sleeper or someone who wakes easily: 10 to 15 minutes
Average sleeper: 20 to 25 minutes
Heavy sleeper who often sleeps through alarms: 25 to 30 minutes

If you are not sure where you fall, start with 20 minutes. The goal is to begin the ramp while you are in a lighter sleep phase near the end of your sleep cycle. If you find the alarm does not feel gradual (you wake up startled by a loud sound), increase the ramp duration.

Step 4: Position your phone for the best flashlight effect

The flashlight effect works better when light reaches your eyes. This is harder to control than it sounds.

Gently simulates a sunrise by transitioning the light from warm, dim tones at the start of the ramp through to a brighter light by wake time, rather than switching the flashlight on at full brightness immediately. This colour progression is part of how the app mimics the shift from dawn to daylight.

Practical positioning tips:

Place your phone face-up on a nightstand or bedside table
Point the camera end (where the flashlight is) toward your face or toward the ceiling above you
If your room has a white or light-coloured ceiling, pointing the flashlight upward reflects a more diffuse light into the room

Avoid placing the phone face-down or under a pillow (which some people do to silence overnight notifications). The flashlight effect requires the phone to be facing upward or toward the room.

Note: if you share a bed with a partner who wakes at a different time, the flashlight may disturb them. In that case, keep the light feature disabled and rely on sound only.

Step 5: Choose a calm starting sound

Gently offers several built-in sounds for the ramp phase. Choose something that starts quietly and can build without being jarring.

Good choices tend to be:

Nature sounds (birdsong, soft rain, gentle wind)
Calm instrumental music with a slow tempo
Low-frequency tones that increase gradually

Avoid sounds that are staccato or percussive at low volumes, as they tend to snap you awake rather than ease you up. The sound you choose should be something you could theoretically lie listening to for a few minutes before needing to get up.

The end point of the ramp (the full-volume alarm) can be a more insistent sound if that is what you need to guarantee you get up.

Step 6: Test on a non-critical morning first

Before relying on this setup for a work morning, test it on a Saturday or Sunday. This gives you a consequence-free opportunity to calibrate.

After the test morning, ask yourself:

Did the ramp actually feel gradual, or did I only notice the alarm when it got loud?
Was I already half-awake before the alarm reached full volume?
Was the flashlight helpful, annoying, or not noticeable?
Did I feel notably better or worse than usual when waking?

Adjust settings based on your answers before using it on a weekday.

Common problems

The flashlight is not bright enough to make a difference. Phone flashlight brightness varies significantly by model. On some devices it is genuinely useful; on others it is barely noticeable in a darkened room. If your flashlight seems too weak, try pointing it toward a white wall or ceiling for reflection. If this still does not help, consider a separate sunrise lamp. Gently will still provide the sound ramp benefit without the flashlight.

The alarm is not waking me up. Two things to check. First, confirm that your phone's volume is high enough. Gently respects system volume, so if your media or alarm volume is set low, the ramp will be quiet throughout. Second, increase the ramp duration or extend the final alarm so it rings longer before requiring manual dismissal. If you are a genuinely heavy sleeper, start with a 30-minute ramp and a loud, insistent final alarm tone.

My phone battery is draining overnight. The flashlight is the main battery consumer if it runs for 20 to 30 minutes. Keep your phone plugged in overnight. Most people already do this. If you cannot charge overnight, disable the flashlight feature in Gently settings and use the sound ramp only.

FAQ

Can I use Gently alongside another alarm app as a backup? Yes. Set your Gently alarm as the primary, and add a standard alarm in your phone's clock app for 5 min after your target wake time as a fallback. This is useful during the calibration period before you are confident in the setup.

Does Gently work with Do Not Disturb? Gently is designed to override Do Not Disturb for alarm sounds, similar to the built-in clock app. You should not need to disable DND for Gently alarms to fire. Verify this during your test run on a non-critical morning.

What if my wake time varies on different days? Gently lets you set different alarms for different days. Set a separate alarm for weekdays and another for weekends if your schedule differs. Consistent wake times are better for your circadian rhythm, but if your schedule requires variation, configure each day individually.
