I’ve been using this for years and it definitely helps me identify what things are helping me sleep by using the notes feature. I would love more control with the notes, though - as it is, you name it once and you can never change it. I also just have a giant list of all the notes I’ve made and it just gets bigger with no way to organize the notes into categories or folders. By “notes” I’m referring to things I created to track how they affect my sleep quality like “took melatonin” or “slept alone”, so over time the list just keeps growing as you add new sleep remedies or other things you realize may be affecting your sleep. Also, I love the slow wake up, it’s so much nicer than being jolted awake, but I hate that once the time you’re supposed to be awake arrives, you can’t go back to sleep or snooze the alarm. At that moment, if you fall back to sleep, you’re screwed, and since it won’t let you go back to sleep, it also stops tracking your sleep if you do go back to sleep. There’s a snooze button when you don’t use slow wake up, so why not have a snooze or “continue sleeping” option for the slow wake up? It would make my sleep data so much more accurate.

I have been using Sleep Cycle since the iphone 4. Until today the app contained a relatively unprocessed graph view of overnight activity. The most recent update changes these graphs, the replacement is more processed and is much more highly smoothed to highlight sleep stages. This change reduces utility of the app for individuals with disturbed sleep or other difficulties. This new graph substantially cuts the the ability to view more raw information about body activity during sleep. This loss seems particularly enhanced when using accelerometer mode, where the data in question is a more direct proxy _of_ body activity. (To the devs: I know this is like the XKCD where every change breaks some bull use case meme, I'm literally a dev myself, but the old graph _preserved information that is now lost_ - that's a data visualization bug. It happened to be useful to some people, and that use case Is _broad_ - anyone who looks at their sleep stages and thinks it might not track very well could easily see that recorded activity in the old graph and confirm/deny that extra overnight activity occurred. Hopefully a fix is as simple as adding a toggle for reducing a smoothing factor in the graph for people that desire it, a virtually zero-maintenance addition. Please spend some time trying to incorporate this and document the utility of retaining such a view. Maybe throw in a comment about how this is _particularly useful for sleep walkers and people with disturbed sleep patterns due to dissociative disorders and PTSD._)

I wish Apple would allow us to decide which applications receive automatic update updates instead of an or nothing method. I bought this application before it was a subscription. Every update has increased how bloated it is, but last night was the final straw. When you were already sleepy and doing the very last thing most people do every night (setting your alarm) the last thing you need is some variable to change and have some woman start talking as soon as you set the alarm. To make it worse, there was no obvious way to change it, disable it or shut her off. I thought I had figured it out by pausing her, but turns out it disabled the alarm altogether, which made me late for work today.If you wanna make a more complex app that has more feature features fine do it, but when people rely on a basic simple alarm, and you change that, you lose their trust. I’ll go back to the Apple alarm, which is just as effective as this. If it comes to reliability or features for an alarm clock, I’m gonna go for a reliability every time.How sad it is to have seen this application deviate so far from its original ethos that attracted so many people. Now it’s “let’s see how many people will subscribe to this new feature that we forced down their throats and hid the ability to disable it somewhere in the settings when they’re at their most mentally exhausted.”
