What the developer says changed (the verdict above weighs this against what reviewers report):

Bug fixes plus the recent improvements: -- Added support for Blood Oxygen to Sleep Tracking. • Sleep Tracking Sleep tracking monitors your sleep, blood oxygen and heart data while you sleep. It also analyzes your sleep data and generates a customized sleep score based on how long you slept and how much of each sleep stage (Awake, REM, Core and Deep) you got. You can view your sleep score and your sleep and heart data on a user-friendly dashboard that shows you graphs, trends, and insights. Sleep tracking is compatible with any device that supports Apple Health. However, to get the most accurate and comprehensive data, you need to wear an Apple Watch while you sleep. • Alarm Clock You can choose between the timer (that's always been in the app) and the new alarm clock. The alarm clock lets you choose from a variety of alarm sounds. You can also hit Snooze if you want a little mor

Who it's for

This app is for individuals who rely on fan white noise to sleep, especially those who travel frequently and need a portable sound solution . It is not recommended for users who are easily disturbed by loud, unexpected audio, or who are sensitive to intrusive advertisements, especially given reports of inappropriate content R5R20.

Evidence note: The sample of recent reviews shows a strong negative trend, primarily due to ad implementation, which contradicts the app's high lifetime rating. The developer's notes mention 'bug fixes' but do not specifically address the ad issues that are a major complaint in recent reviews.

  12. [R9] 4/5 · US Ads with noise!: I love this app and have for a while but you gotta stop these ads with sounds. It will make noises when I am putting on the fan in a quiet room when my wife or kids are sleeping
  13. [R12] 4/5 · US Stupid Loud ads: For an app meant to help you sleep, their stupid advertisements will come on full volume while trying to start the app and wake up anyone fortunate enough to have already fallen asleep. Not too bright on a sleep app. Will be changing if it doesn’t stop :(.
  14. [R29] 4/5 · US I love it! But…: I love it so much and I would 100% give it five stars if the dang amazon ad didn’t play at FULL BLAST every single time I open the app. like i’m talking FULL BLAST TRUMPET at 3 in the morning. not fun. but other than that, great app

  20. [R8] 1/5 · US Used to work great!: This app used to work great until a big update. Now it doesn’t work on my iPhone.
  21. [R42] 2/5 · US Works great but…: Worked great until recent update, cannot get out of ads since they are at the top of the screen. Had to download a new app that worked.
  22. [R43] 1/5 · US App was great: Now the ad pops up and in a way where it shifted the banner up where it is too high up on the screen so you can’t start the fan. Even if you force close and bring it back it just takes you to the ad and you can’t click to use the fan. Been using for years and had to switch to another app
  23. [R3] 3/5 · US Too much singing in background!: The singing in the background wakes me up during the night and drives me nuts! Sometimes it sounds like people talking. That wakes me up as well.
