That way the save button is not reachable. Please fix that bug. ### 2/5 — Update made it worse *2026-05-16, version 5.452* This latest update has made the app harder to use. The notes that you can add to large but you can’t scroll or save them. The brightness is much too bright. Please adjust. ### 2/5 — Screen too bright since latest upgrade *2026-05-15, version 5.452* I’ve used Sleep Time for well over a decade and have genuinely loved it. That’s why this latest update is disappointing. The new interface has too many bright white buttons and screen elements, making it much too bright for nighttime use. For a sleep app, dark, low-light usability should be a priority. Please consider adding a true dark mode or reducing the brightness of the buttons. I’d love to keep using the app I’ve trusted for years. ### 2/5 — Fix your UI *2026-04-08, version 5.416* The X button to continue into the free app shouldn’t be shoved into the upper right corner where it’s nearly IMPOSSIBLE to hit and close out of the ad. Shame on you ### 4/5 — Generally a great free app *2025-08-17* I use the app nightly to monitor my general sleep patterns. Love that it has a built in alarm that gradually builds/gets louder. Only reason I haven’t given it 5⭐️ is every now and again for some reason the alarm doesn’t go off, will say it only sounded once (as opposed to snoozed) but it actually didn’t. You know this as it will be half an hour after it was set that I wake and it would have needed snoozing several times during that period. Annoying when it means I’m late but happens so infrequently I can’t be bothered looking for an alternative ### 3/5 — Good, but something wrong with it *2025-04-28, version 5.416* It was an amazing app before, but recently the app just hasnt been playing the alarm sound and ive been late to places on multiple occasions. Please look into this issue further ### 2/5 — Why doesn’t alarm play through headphones?! *2025-03-06, version 5.416* I used this app years ago in college and really loved it so decided to re-download it now to get insight on my sleep patterns. The issue is that I now live in a horribly noisy area or people rev their car engines and screech their tires constantly and so I sleep with headphones in. We all know that the standard alarm on iPhone is trash and doesn’t play through headphones. But neither does this app. So now it’s not going to be usable for me. Someone needs to fix this problem and they would be the most popular alarm app ever ### 1/5 — Ads won’t close *2024-09-04, version 5.416* Used this app for years for my alarm. The ads won’t click away now to even use it. Deleting and getting something else ### 1/5 — Ads that can’t be clicked away *2024-08-28, version 5.416* This app has now started to have ads that can not be clicked away, and they don’t time out. Makes the app completely useless. ### 1/5 — Incompréhensible *2024-05-15* Je comprends pas à quel moment faut payer pour régler son sommeil et dormir paisiblement c’est inadmissible ! ### 1/5 — loud ads, ads in foreign languages, bad reviews *2024-04-24, version 5.416* I've had the app for years and the devs have experimented with ugly ways for them to make a buck off of you - playing loud pop up ads as you're setting your alarm - I even have gotten ads in foreign languages where the close button is (I assume) the word "close" in that language... not to mention how they hound you to set up an account (more data collection). I've also had my share of mid-night crashes that cause me to miss waking up on time. very unsavory and antagonistic view of their user base - avoid this app. ### 1/5 — Alarm no longer makes noise *2023-12-21, version 5.416* Have waken up late for work twice now due to the alarm not making any noise. Will be switching apps immediately ## Most critical reviews (10 lowest-rated) ### 1/5 — Breaks my Eardrums *2026-08-05, version 5.456* I've been looking for an app that can wake me up a little less aggressively than my normal alarm, and I thought this might work with the 30 minute wakeup, but no. I often listen to white noise or an audiobook through headphones to fall asleep, but when this first alarm starts, it increases whatever other audio is playing to 100%, blasts my eardrums, and shocks me awake more aggressively than my regular alarm. I've tried turning on "air play" in the app and turning the volume for the alarm itself to 0, nothing works. App doesn't have support available beyond generic faqs so here we are. ### 1/5 — The notes don’t work! *2026-06-05, version 5.454* After the recent update the adding of the notes/ tags after you set the alarm don’t work. The icons are too big to “submit” or whatever it was and if you swipe down it goes away. Fix this. ### 1/5 — Why log in? *2026-05-15, version 5.452* Been using this alarm app for nearly 15 years. Why do you need an account to use it now? Why is there no guest option? I just want to set my alarm. This is heartbreaking. I knew something was in the works when the ads change about a month ago. Sad ### 1/5 — デザイン改悪 *2026-05-14* アップデートでデザインが一新されましたが、断然以前の方が良かったです。 元に戻して！！ ### 1/5 — Stops working all the time *2026-05-01, version 5.416* This app works for me 1/10 times. Every other time when I wake up and go to shut it off, I find it automatically stopped at some point and didn’t count any of my sleep rendering it useless ### 1/5 — Cash grab *2026-03-26, version 5.416* After using the app for 5+ years with all features unlock for a small fee, the app has reverted my status back to free version with adds. Not trying to pay additional monthly fees for an application feature I previously had. -app deleted- ### 1/5 — NO DATA PRIVACY *2026-03-10, version 5.416* Seriously, READ the privacy terms and conditions. They openly admit to saving your “social media log in credentials” if you input them into the same device you use their app on. They save all the data about you they can get their hands on from your phone. Do not download this app onto a personal device. ### 1/5 — Bug ao integrar com Health (Apple) *2025-12-18* Segui todas orientações para permitir o acesso aos dados do “Health” mas os dados referentes ao sono não migram. Migram apenas outros dados (como “steps” e “workouts” ) que não é o meu escopo de análise e nem o que o app promete. Tentei reportar o bug, sem sucesso. ### 1/5 — Ticket : 79487 *2025-02-10, version 5.416* I have an issue in receiving sleep reports and I raised a ticket a while ago but didn’t receive any response from technical support. ### 1/5 — Регистрация *2024-10-31* Приложение всегда просит регистрацию, невозможно ничего сделать... ## Most praised reviews (10 highest-rated) ### 5/5 — Great for groggy sleepers. *2026-03-12, version 5.416* Great app. Really helps me wake up in the morning. I really wish it had the ability to record sound, but even so, I’d definitely recommend it for people who struggle to wake up and feel groggy in the mornings. ### 5/5 — Free of cost *2025-07-29* The app is free, and the alarm, which is the main feature, is free too. Best app for IOS ### 5/5 — Great app for sleep tracking *2025-03-24, version 5.416* This app functionality is fantastic, and it uploads automatically to my Apple Health and Personify apps. ### 5/5 — Perfect and free *2024-12-23, version 5.416* I needed an app to track my sleep for our insurance plan to pay us. I tried app after app for a week and all wanted a subscription. Finally I found this one and it worked perfectly! ### 5/5 — No consume batería *2024-10-05, version 5.416* Es una app que no consume trabaja batería, sencilla y concreta ### 5/5 — Best free sleep app *2024-07-11, version 5.416* This is the only free sleep app I’ve found that actually works! I have considered upgrading, but I can’t find anything that explains the premium features. I wish it would give some examples of sleep reports or sleep programs, but that’s literally my only complaint, so, highly recommend. ### 5/5 — Great application for monitoring your sleep *2024-04-18, version 5.416* It is accurate providing you with detailed analysis of your sleep and hints to improve your sleep. ### 5/5 — Dependable *2024-02-18, version 5.416* I’ve been using this app since 2013, I count on it everyday. I like that it provides a gentle, natural wake up more in tune with my body’s rhythm. It’s also important to me to track how well I’m sleeping each night. ### 5/5 — Waves *2023-09-28, version 5.416* Love the waves on the beach sound, so peaceful. ### 5/5 — D *2023-09-05, version 5.416* I like it, I think it's great 🥰 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
