When your alarm goes off in the morning, is your first reaction to throw it against the wall? The problem isn’t with you—it’s with your alarm clock. Thankfully, Sleep Cycle offers a clever solution for improving your rest. Rather than yanking you from your slumber at a specific minute, the app analyses your sleep patterns and then picks the moment you’re sleeping lightest (within a half-hour window you define) to rouse you gently. Best of all, unlike some smart alarms, this one doesn’t need extra hardware or require your device to be resting on your bed: it tracks your sleep using just its microphone!

I’ve always had trouble trying to get up in the morning from my normal alarm so I decided I’m just going to get a proper app. I was looking for some good app that will help me and I came across sleep cycle. It looked really good and had great features I tried it for the first few days and it was great!! I happily woke up in a light sleep and I actually was ready to get out my bed instead of my normal alarm which was insane!! I also love how as soon as you wake up if tells you have long you slept for unlike other sleep apps you have to wait along time just to find how long you slept that night?! Sleep cycle is just so easy to use and is absolutely great for people who have trouble waking up in the morning! Even though I don’t have the premium it still works great and fine! So I am very impressed with how great this app is! Question- Does sleep cycle still work even with people sleeping in the same room near your phone or can it mess up the cycle a bit hopefully not because I have roommates how like to snore and I hope that doesn’t affect anything!!😀 5 stars!⭐️⭐️⭐️⭐️⭐️

Where have all the stats gone!?!

Dear Sleep Cycle

What have you done? You stated that all of the original features remain in this visual rework however, that’s clearly not the case.

Put simply, where at the numerical statistics for anything longer than seven days gone? Now when changing period of observation within a specific fittest category worth the grass change right up to complete data as before, the textual average hello remained for just seven days.

So your original statement that all features have a present before having carried over is incorrect. I have been a subscriber to your app since around 2000 and, for over seven years now, I have become an expert user thriving and driving both my sleep and that of my family on the ability to compare specific numerical data across the differing period of observation.

This update now deprives us of this key capability which differentiated yourself from the rest the market and enable me to drive and manage our sleep effectively.

I am sure that I am not alone in speaking for most significantly long-term users whom have been making use of these key functional elements within your app, in saying that, without this functions, your app becomes of questionable use.

I would urge you to reconsider your redevelopment and absence of these stats accordingly as I along with his other expert long-term users will after the best part of a decade of use be forced to look elsewhere for the data which you have deprived us of access to.
