## What is Sun Alarm Clock?

Wake up with the sun. Never miss golden hour. Sun Alarm turns sunrise, sunset, and other sun and moon events into reliable daily alarms — at any place on Earth.

**Set alarms for natural events**
• Sunrise and sunset  
• Solar noon  
• Golden hour and blue hour (morning and evening)  
• Civil, nautical, and astronomical twilight  
• Moonrise, moonset, and moon transit  
• Moon phases: full moon, new moon, first quarter, third quarter, crescents, gibbous  
• Custom sun altitude (e.g. “sun 5° above horizon”)  
• Next equinox and solstice  

**Flexible timing**
• At the exact event time, or any number of hours and minutes before or after  
• Alarms follow the event every day (or next occurrence for moon phases and equinox/solstice)  

**Any location**
• Choose a place on the map or search for a city  
• Correct time zone for the chosen location, so alarm times stay accurate when you travel or when daylight saving changes  

**Designed for daily use**
• Multiple alarms, each with its own type, place, and offset  
• Optional names 
• Snooze and clear from Lock Screen and notifications  

SunAlarm uses your chosen location’s coordinates and time zone to compute event times, so you get one less thing to think about—and one more reason to look up at the sky.

### 5/5 — Most of the time it works

*2026-05-27*

I noticed that sometimes the alarms just don’t go off. I went through their qna to find a solution but couldn’t find a solution. It seems that if you have two alarms related to the same event it might not work. Example; one alarm for an hour before sunset and an alarm for sunset exactly  even if you that isn’t the case occasionally they just don’t go off.

### 1/5 — Doesn’t work anymore

*2026-03-18*

The two free alarms, they don’t work. Waste of time to download it.

### 1/5 — March 2026 screwed up this app

*2026-03-07*

When I first reviewed this app three years ago, 2023. It was a 5-star app, now (March 2026) the latest update has made this app useless. Definitely, wouldn’t recommend buying it until it functions as it did before this update. 
The Problem: No longer does it just alert — rooster crow, or whatever — and be done/silenced until the next sunrise or sunset. Now you must physically turn it off.
Every. 
Time. 
I hate losing this app. Hopefully, it’s a bug and they will fix it. Or maybe it’s feature designed to drive people away???

### 5/5 — Excellent App

*2024-08-24*

Exactly what I wanted !!

### 5/5 — Funktioniert sehr gut

*2023-04-04*

Von der Sonne allein wecken geht nicht. Die Aufgangszeiten herauszufinden mühsam. Dafür ist die app da. Ich hab da ein kleines Problem. Wie entferne ich Orte? Update : Wenn Stromsparmodus in Betrieb ist, ist die Hintergrundaktialisierung auf aus. Da mein Smartphone immer benutzt wird, ist der Akku nach vier Stunden leer. Wenn geladen wird, ist das im anderen Raum. Hätte ich das mal vorher ausprobiert, dann hätte ich die 2,49€ nicht ausgegeben.

### 5/5 — The Rooster Tells Me

*2023-02-05*

I love it. The rooster tells me when it’s sunrise and sunset. He’s a good ol’ reliable rooster.

### 5/5 — Perfect!

*2022-11-16*

I like knowing when the sun is rising and setting. This is the perfect app for that function. I do wish it didn’t turn itself off but it does alert you that it’s going to do so. All you have to do is open the app to reactivate your alarms.

### 3/5 — Pro Kauf klappt immer noch nicht!

*2021-10-02*

Trotz gegenteiliger Ansage.

### 5/5 — Fehler beim Kauf der Pro-Version

*2021-03-29*

Der Kauf der Pro-Version klappt nicht.

**Developer response:** Vielen Dank für den Hinweis!
Das Problem wurde inzwischen behoben.
