Alarm Clock is a free Android app from the developer Smart phone app, listed under Tools. It gathers four everyday timekeeping tools into one download: an alarm clock, a world clock, a stopwatch and a countdown timer. The main reason to consider it is convenience, since those jobs often end up spread across separate apps.
The app has been available since September 2021 and has passed five million installs, with a 3.9 average from just under twenty thousand ratings. That is a healthy audience for a utility of this sort, and it suggests the core jobs are being handled well enough for people to keep it around.
What I like about the pitch is that it does not pretend to be more than it is. For a daily utility, that restraint is usually an advantage.
A straightforward fit for daily routines
This app suits anyone who wants a single place for the timekeeping tasks that come up in an ordinary week. If you set a wake-up alarm each night, time a run or a work interval during the day and occasionally need to know what the clock says in another city, one app covering all three saves you from juggling separate downloads.
It also looks like a reasonable choice for heavy sleepers, since the developer describes loud alarm tones and vibration alongside a gradual volume increase. Being able to choose between a gentle rise in sound and a more forceful wake-up covers both the person who dislikes being startled and the person who sleeps through a quiet tone.
Students, home cooks and anyone working to a schedule should find the timer and stopwatch useful for the small measurements that fill a day. None of this is specialized enough to need training or setup, which is the point of a utility like this.
Alarms that adapt to how you sleep
The alarm side is the most developed part of the app. You can keep several alarms going at once, each with its own settings, and choose whether an alarm repeats daily or only on particular days of the week. That covers the usual split between a weekday wake-up and a lazier weekend schedule without resetting anything by hand.
Alerts can arrive as sound, vibration or light, and the volume and tone are adjustable. The crescendo option raises the volume gradually rather than jolting you awake at full blast, while loud tones are there for anyone who needs a firmer nudge. Snooze settings let you extend your rest when you are not ready to get up.
The developer describes the controls for switching an alarm off as intuitive, which matters more than it sounds. A half-awake person should not have to think about where to tap, and the design choices here seem to be made with that moment in mind.
World clock, stopwatch and timer
The world clock shows your local time and weather automatically, and you can look up the current time in cities around the world. A time zone converter lets you compare the difference between two locations, which is handy when you are arranging a call with someone in another country or checking whether it is a reasonable hour to ring a relative abroad.
The stopwatch measures intervals down to the millisecond and includes a laps feature for recording split times. You can pause, resume and reset it as needed. That makes it usable for timing exercise sets, cooking stages or any repeated task where you want to see how each round compares with the last.
The timer handles countdowns for cooking, exercising or studying, and it keeps alerting you once the countdown finishes even if the app is running in the background. That last point is the one that matters most for a timer, since the whole purpose is to be reminded while you are doing something else.
What the free download includes
Alarm Clock is free to download, and it is supported by advertising. In-app purchases are also available. Those terms are worth weighing before you commit to using it as your only alarm.
For a utility you rely on every morning, ads are the part I would think about most. I would treat the free version as the starting point and decide from there whether the app earns a place in your routine.
The app is rated for Everyone and has no age restrictions worth worrying about. It has also been updated recently, with the most recent release dated September 2026, which suggests the developer is still working on it rather than leaving it to sit.
How it compares with other options
Most phones ship with a clock app already installed, and that is the first alternative to weigh. A built-in tool costs nothing, carries no advertising and is already integrated with the system, so the question is whether this app's extra options, such as the world clock converter or the crescendo alarm, are worth adding another download.
Some focus narrowly on waking you up with puzzles or missions to force you out of bed, while others lean on sleep tracking. This one sits closer to the general-purpose end, covering four tools rather than specializing in one.
If you mainly need a stopwatch for training, a sports-oriented timer may offer more structure. If you mostly need world times, a travel-focused clock may present them more clearly. Alarm Clock's appeal is breadth: one app for the small timekeeping jobs rather than a specialist for each.
A sensible daily companion for basic timekeeping
Alarm Clock is a well-rounded free utility that covers the timekeeping basics without overcomplicating them. The alarm options are the strongest part, with repeating schedules, crescendo volume, loud tones, vibration, light alerts and snooze settings all in one place. The world clock, stopwatch and timer round it out into something you can leave installed and use most days.
The caveats are straightforward. It is ad-supported with in-app purchases, and the 3.9 average from nearly twenty thousand ratings suggests a solid but not outstanding reception. Anyone who wants a single-purpose alarm app with a specific gimmick may find this one too broad.
I would suggest it to people who want one dependable app for alarms, countdowns, intervals and world times, and who do not mind advertising in a free tool. If your phone's built-in clock already does everything you need, there is no urgent reason to switch, but this is a reasonable alternative if you want more alarm flexibility in one place.
The short verdict
A free, ad-supported four-in-one timekeeping app that suits anyone wanting alarms, a world clock, a stopwatch and a timer in one place.

Alarm Clock: frequently asked questions
What can I do with Alarm Clock besides setting an alarm?
The app bundles four tools: an alarm clock, a world clock, a stopwatch and a countdown timer. The world clock shows your local time and weather and lets you check times in cities worldwide, with a converter for comparing two locations. The stopwatch records intervals down to the millisecond with a laps feature, and the timer handles countdowns for cooking, exercise or study.
Can I set an alarm to repeat only on certain days?
Yes. You can create several alarms and choose whether each one repeats daily or only on specific days of the week. That makes it easy to keep a weekday wake-up separate from a weekend schedule. Each alarm also has its own volume, tone and snooze settings.
Does the timer still alert me if I leave the app?
The timer keeps alerting you when a countdown finishes, even with the app minimized. That means you can start a countdown and move on to something else without keeping the app open on screen. It is the behavior you would want from a timer used for cooking or study sessions.
Is Alarm Clock free, and does it have ads?
The app is free to download and is supported by advertising. In-app purchases are also available. The free download is the place to start if you want to try it.
What is available for people who sleep heavily?
The alarm settings include loud tones and vibration for heavy sleepers, alongside a gradual volume increase that wakes you more gently. You can also adjust the volume and tone to suit your preference and use snooze if you need a few more minutes. Alerts can arrive as sound, vibration or light.
