Zen Sleep Cycle Alarm Clock

So far I have been using it for a few nights now and I have upgraded the version. It wakes me up during deep sleep and never in light sleep so it's hard to have a pleasant wake. Will continue to monitor it. Update 4/23/17: This alarm clock still does not wake me up during light sleep and sometimes it doesn't go off at all. I keep my phone alarm as a backup. I wish I could get a refund for this app. Not happy with it.

I really enjoy this app! It wakes me up in a gentle way (who likes a hostile wake up call in the morning?!) I also love being able to track my sleep cycle! I just wish I knew how it works...magic?

This app has been surprisingly accurate. I am a terrible sleeper so this has been so helpful. A little scary to see my insomnia charted but hey!

Utterly useless. Doesn't do anything - paid for pro but the Stats etc empty. It's not done anything.

It does wake you up nicely - sometimes - 3 out of 6 nights the alarm went off, the rest? No idea. It tracks your sleep - supposedly - if it doesn't crash. I had it active for 6 nights now, it tracked 5 of them, 3 show in my stats, the other times it crashed and didn't save or like now it just didn't save last night for whatever reason. I payed for the app though it wasn't much but that makes it even more disappointing.

The first night I used it, the time set for between 645 and 715. I woke up at 7 on my own. It didn't go off until 715. I thought it was supposed to register when you were in lighter sleep to wake you up.

Not really user friendly at first but works wonders at waking me up at the perfect time. I am far more refreshed using the app and definitely recommend sticking it out a couple days and tracking your results.

This app is awesome! I always have a ton of trouble waking up in the morning...As we all probably do. This is exactly what I needed.

Every time I opened it, it would say "unfortunately, zen has stopped". I re-downloaded it a few times but got the same results. Never got to try it out.

What, I have to keep the phone plugged in, and worse yet, keep it next to my pillow as I sleep throughout the night?! No, thank you. Immediate uninstall.

I enjoy not being suddenly awoke and waking up feeling rested instead of struggling to get out of bed

This app is great. It has an what user interface and does exactly what it claims to do. I have been sleeping better since I've installed it.

This app is beautifully designed. I am constantly looking for new sleep apps and I do believe I just found my permanent one .

I love the dream log and the design but the alarm doesn't ring in my lightest sleep

Very accurate and helpful. I wake up feeling more rested.

Seems pretty legit so far. I'll try it out for a few weeks and see how it goes.

Where has this been my whole life!!

Like that i can record my dreams

Woks very well for me!

I feel more awake during the day since using this app!

Great app! Really helps, especially when I've worked out that day!!

Does what it says!

I love the gentle wake up!

Pretty good. Need to play with it more.

Interesting app! Fascinating technology!

Very easy to use

Love it

Seems interesting so far. I wish you could change what buttons were on the main page. I don't drink alcohol or anything with caffeine, so I would prefer to have other options there. It would be nice to have an option to mark if I have a headache the next morning, as I'm trying to track that and see if it's related to sleep habits. I do wish this was available as an app for my Samsung watch. I have a very very basic sleep tracker for my watch, and it would be interesting to tie that functionality with this app. (I don't particularly like sleeping with my phone on the pillow as opposed to the nightstand.

Only been using it for a few days. But so far, I like it! I don't have the upgraded version, but even just the basic is fine. It seems fairly straightforward and easy to use. I'm not a morning person, at all, and I'm not going to claim that this app magically changed that, but it does make mornings a little less awful. So, thanks. :)

It seems like a great app, but it's pretty unclear. I'm not sure if it is supposed to record my sleep phases or if I need to upgrade for it to do that? It hasn't recorded a thing. I'd hate to upgrade and then find out it was supposed to be recording but just hasn't been working this whole time. However, I do feel better waking up so it does do that.

I've never been a morning person before but this app has changed that. I wake up feeling rested instead of groggy and have more energy all morning. Thanks for saving my mornings!

It needs some sort of instructions when you first download it, but other than that, it looks good, feels nice. I'm not exactly sure on how to use the app 100%

I'm not really sure what it does or if it's effective. I've used it a couple of nights, it wakes me up at a random time within a 30 minute window I set for it.

I've seen others that do this before, this one did the job well, woke up feeling refreshed and alert

Not sure how to use this app properly since there are no instructions. Do not know what the wheel is for or how to use it.

Great app, bit messy to navigate sometimes

So great!

This app doesn't give you instructions on how to use the sleep wheel. I paid for the upgrade at $3.99 and still can't utilize the bells and whistles that come with it because it hasn't upgraded even after restarting my phone. Then I find out the upgrade went down to $2.99! I enjoy your other apps, but this one is out the gate not as easy-to-use.

Same problem as other users. Paid for the upgrade to premium twice (stupid me) but the app still hasn't unlocked. No option for refund? I've been robbed!

I paid for an upgrade to get rid of ads but it hasn't been recognised by the app. Sent an email but got an autoreply warning me not to expect a response due to high message rates. Help section only tells me how to use the app and 'like' it on social media...will try to get a refund I think.
