The Best Alarm Clocks of 2025
No one likes getting up in the morning — unless you’re an early bird — but a good alarm clock makes waking up just a little easier. We’ve tried dozens of alarm clocks, from the gentle, gradual mornings of sunrise alarm clocks to silent alarm clocks for waking up without disturbing the entire household. Regardless of your personal alarm tastes, we’ve picked out the best alarm clocks for every type of sleeper.
When choosing an alarm clock, considering your sleep needs is a must. “Light sleepers may want as few distractions and artificial light as possible,” said Alex Dimitriu, MD, the founder of Menlo Park Psychiatry and Sleep Medicine. “Deep sleepers may want an alarm that is loud or gradually loud, possibly with light or a sunrise simulator to facilitate waking up from a deep slumber.”
Whether you’re a light or heavy sleeper, we’ve found the best alarm clocks on the market. Our top pick is The Loftie, a sleek smart alarm with features like an adjustable nightlight and Bluetooth speakers. For heavy sleepers, we recommend the Sonic Bomb Alarm Clock, a downright boisterous alarm featuring vibrations, flashing lights, and loud sounds.

Loftie The Clock
The Loftie is constantly updating its firmware to provide a unique and healthy wake-up experience with a growing library of pleasant melodies.
What sets the Loftie apart from other best alarm clocks is its two-phase alarm system. The first alarm is a gentle tone that helps my body and mind wake up slowly. The second is a louder melody that gets me out of bed. This method is effective in reducing sleep inertia (morning grogginess).
Since its launch, Loftie has added more sounds, alarms, and new features. It works as a white noise machine, Bluetooth speaker, and sleep timer. You can set multiple alarms from the device and choose the type of sounds you want to wake up to. With only three buttons at the top, it’s simple to use.

The Loftie was designed to break the bad habit of scrolling through your phone during your bedtime and morning routines. Instead of looking at social media right before bed, I enjoyed falling asleep to the Loftie’s included breathing techniques, sound baths, and bedtime stories. The display dims automatically as the night progresses, and a warm amber glow serves as a gentle, adjustable nightlight.
Setting up the clock includes downloading the required Loftie app (available for iOS or Android). For the most part, you can do everything on the device and stay out of the app, unless it’s time for an update.
Overall, the Loftie did a fantastic job at waking me up on time every day in the most pleasant way possible.
Best sunrise
Phillips SmartSleep Wake-Up Light Alarm Clock
The Phillips SmartSleep Wake-Up Light has a unique spherical design that creates a beautiful sunrise simulation, and features many of the same premium settings as the more expensive Philips Smartsleep Connected.
If you are really looking to set up a morning and night routine, this is a great pick for intuitive sleepers that want to start analyzing their sleeping habits. With the ability to customize which sounds and lights to wake up and wind down with, you are able to relax more naturally during your sleep routine.

While testing, I woke up refreshed each morning. The snooze function is simple: just tap anywhere on the clock to snooze your alarm and sleep for nine more minutes. You probably won’t need to snooze it, though, since the gradually increasing warm glow wakes you up naturally.

Best for heavy sleepers
Sonic Alert Sonic Bomb Alarm Clock
Even if you sleep like the dead, you’ll spring back to life at the first blast of the crazy-loud alarm, vibrations, flashing lights, and bright red display of the Sonic Alert Sonic Bomb Alarm Clock.
With its puck-shaped shaker, the Sonic Bomb Extra-Loud Alarm Clock uses a powerful vibration to help ensure that you wake up on time. It’s very abrupt, so it won’t rouse you gently, keep this in mind when considering your favorite alarm clock pick.
Vibration alarms might work well for people who have trained themselves to sleep through sound alarms or who can’t hear them. You put the puck under your mattress, and you’ll feel an intense buzz when your alarm goes off. Even through my very thick mattress, I felt the alarm vibrating on the other side of the bed. I could also hear the sound of it shaking, too. If you’re trying not to wake your partner, this isn’t a great solution.
Jenny McGrath/Business Insider
For a budget alarm clock, the Sonic Bomb is fairly customizable. You can choose only the vibration, just a buzzing sound, or combine them. There are a few options for the buzzer’s tone, and you can turn the flashing lights on or off.
You can also change the snooze duration, which isn’t always something you find on similarly priced alarm clocks.
One big drawback is that you have to remember to between the two alarms if you don’t want a weekday alarm going off on the weekend. There’s no way to set the alarms for specific days, but you can have them both go off every day.
Best smart
Hatch Restore 3
The Hatch Restore 3 now features phone-free controls and enhanced sound quality, offering you even more ways to personalize your sleep routine with over 50 sounds and 18 light colors, while minimizing screen time for a better night’s rest.
The Hatch Restore 3 is the best smart alarm clock, with a sunrise display, a library of content that span classic alarm sounds to original bed time stories, app connectivity and customizable alarm settings.
Experts recommend avoiding using your phone before bed, but using it to program your alarm clock is certainly handy. With the accompanying app (available on iOS or Android), you can program your Hatch Restore, including display colors and sounds. You can even set a routine, if you find yourself gravitating towards a certain meditation or sleep story at bedtime. The app is free, but you’ll have to upgrade to Hatch+ ($49.99 yearly or $4.99 monthly) to unlock extra features.
Suzy Hernandez/Business Insider
One of the best parts of the Hatch Restore 3 is its versatility — the included app is handy, but you can also control it with the buttons directly on the clock. It’s easy to set it up in advance, then put your phone away and for an easy, tech-free experience the next morning.
Besides smart capabilities, the Hatch Restore is a gorgeous alarm clock with a huge array of features, including 50 sounds and 18 colors, for a personalized wake-up experience, whether you prefer a sunrise or sound-based alarm. The only thing it’s missing is Bluetooth capabilities or radio.

Loudest
Emerson SmartSet
The Emerson SmartSet has the best digital LED time display with easy-to-read large numbers and a beautiful cyan nightlight.
The Emerson SmartSet clock radio has a gradual beeping alarm sound that gets loud enough to wake up even heavy sleepers. Sleep specialist Alex Dimitriu, MD, recommends placing a loud alarm clock for heavy sleepers “far from the bed stand so they would require getting up and walking over to turn it off.”
You can also wake up to your favorite FM radio station that gradually increases in volume. Two alarms can be set for weekdays only, weekends only, or all seven days.
Suzy Hernandez/Business Insider
Its lovely cyan LED time display is large, clear, and easy to read. A soft cyan nightlight turns on and off via a button on top of the device. Other features include a USB charging port and Bluetooth speaker. Unfortunately, you can’t use the speaker to wake up to your own music, though the sound quality is decent for an alarm clock.
The device is easy to navigate, with the buttons located at the top of the device. One issue that I had with this alarm clock was not being able to change the alarm settings while listening to music via Bluetooth. To set the alarms or adjust other settings, you have to stop the radio or music first.
Additionally, even though the nightlight can be fully turned on or off, the time display can only be dimmed and doesn’t shut off completely. Overall, the Emerson SmartSet is one of the best alarm clocks for people who like a big time display, a beautiful cyan glow, and a loud alarm.
Best for time projection
The Magnasonic alarm clock is sleek and easy to set up, with a projector for convenient viewing. It features a blue LCD display with a clear view of the time, day of the week, and indoor temperature.
These stats can also be viewed from an adjustable projector that displays on the wall or ceiling. An auto dimmer turns off both the display and light projector when you want total darkness. You can set two alarms and wake up to your favorite AM/FM radio station or the built-in buzzer.
Suzy Hernandez/Business Insider
Other features include sleep and nap functions, a backup battery, and AUX audio input to listen to your music (though you can’t wake up to AUX audio).
You have the option to set your alarm for Monday through Friday, the weekend only, or just one day. Even though this is a traditional alarm clock, the sound is not abrupt and obnoxious. Instead, it’s a gradual sound that gets loud enough to wake up even heavy sleepers. This alarm clock offers reliability for light sleepers like me, without being too jarring.
The Magnasonic alarm clock lacks some nice-to-have features compared to the other best alarm clocks, including more alarm sound options and Bluetooth connectivity. It would be nice if the display dimmer had more than three brightness levels, too.
Overall, the Magnasonic is one of the best alarm clocks because it is reliable, easy to use, and convenient.
Best for kids
Hatch Rest+ 2nd Gen
The Hatch Rest+ is an excellent choice for parents looking to foster healthy sleep habits in their children. It provides gentle light and sound options along with customizable routines, all in a sleek, compact design. It’s also a more cost-effective option than the original Hatch Restore 2.
The Hatch Rest+ 2nd Gen is an all-in-one device that works as a night light, white noise machine, and alarm. Older kids can also use it as their first alarm clock.
For toddlers who are early risers, adults can set the Rise+ to turn a certain color when it’s OK for kids to get out of bed. Business Insider Reviews contributor Alicia Betz likes this feature that’s popular with a lot of parents. You can turn off the sound so it’s less likely to wake anyone who’s still sleeping. When kids get a little older and need to get up for school, a combination of sound and light can help gently awaken them at the right time.
Suzy Hernandez/Business Insider
While the device is pricey, it does have a nice built-in library of 18 free sounds. The nine different color options can also signal to them it’s time to start winding down for the night and stay as a night light as well. With over eight hours of battery, it can even be removed from the base to be used as a portable night light.
All said, for full use of the Hatch Rest+ 2nd Gen, you’ll need a Hatch+ subscription. The subscription, which is $4.99 a month, extends the clock’s sound and light library. Most functionality is through the app, and the Rest+ does require WiFi to set up.
What to look for in an alarm clock
I spoke with sleep expert Alex Dimitriu, MD, founder of Menlo Park Psychiatry and Sleep Medicine, and relied on my own experience as a sleep researcher and certified sleep science consultant to write this guide.
Alarm tone: Your alarm clock should wake you up the way you want to wake up. If you want to wake up gently you should choose one of our best alarm clock picks that has soothing sounds. On the other hand, if you are a heavy sleeper you are going to want to go with one of our alarm clock picks that has louder sounds.
Aesthetics and size: An alarm clock should seamlessly fit into your room and its style. Your alarm clock should not be a focal point, so try to pick an option that blends into the colors or style of your bedroom.
Source of power: If your nightstand isn’t near an outlet you should look into wireless or battery operated alarm clocks. Make sure the alarm clock you purchase fits into your current lifestyle and habits, not the other way around.
Durability: You want something that’s long lasting, reliable, and overall a good investment. Depending on your sleeping habits and how much you want to spend, a simple alarm clock could be a perfect fit for you. If you want something with added features and perks, you are probably going to spend more money.
Extra features: Bluetooth compatibility, sleep tracking, multiple charging ports, and radio, are not included with most alarm clocks. If you are looking for these extras, make sure to check out the features before buying.
How we test alarm clocks
For this guide, I tested eight of the best alarm clocks and evaluated them on the following criteria:
Setup: For each alarm clock, I noted how easy or difficult it was to set up the time and alarms and how helpful the instructions were.
Performance: I used each alarm clock for a minimum of three consecutive days to get used to the routine and noted how effective they were in waking me up on time.
Alarm sound: I carefully assessed each alarm’s volume and sound selection and noted whether it was a gradual melodic tune and loud enough to wake up heavy sleepers.
Extra features: I tested any additional features of each alarm clock, including Bluetooth integration, sleep timers, apps, projectors, and voice-control features.
Durability: I tested and noted how durable and resistant each was by knocking them off my nightstand to see if they were easily damaged.
Alarm clock FAQs
What type of alarm clock is best for light sleepers?
Light sleepers should look for quieter, gentle alarms and a dimmable display to not disturb sleep. Light sleepers may also benefit from a gentle alarm like the best sunrise alarm clocks.
Why can’t I just use my phone as an alarm?
“Keeping a phone on a nightstand is a bit of a distraction and can negatively impact sleep,” said Dimitriu. It’s better to put your phone away while you sleep. Also, using your phone as an alarm means you’re looking at it first thing in the morning, which isn’t always the most peaceful experience.
What is the difference between silent and sunrise alarm clocks?
Sunrise alarm clocks mimic the light of dawn — usually in soft orange and yellow shades — to wake up a sleeper gradually and naturally. Some silent alarm clocks also use light, but might also use methods like vibrations as well.
What color alarm clock light is best for sleeping?
Use dim red, yellow, and orange lights on your alarm clock display, since these shades have no impact on your circadian clock. Avoid harsh blue and white colors for the best night’s sleep.
Which type of alarm is best for heavy sleepers?
For heavy sleepers, we recommend a loud, sound-based alarm. Quiet or sunrise alarm clocks might be too gentle to rouse heavy sleepers from sleep.
Why do I sleep through my alarms?
If you’re sleeping through your alarms, your body may have become attuned to your current alarm style and trained itself to ignore the sound or light. Try changing alarm chimes or styles, but if the problem persists, always consult your doctor.
