What’s happened since last update!!! ### 3/5 — Was great! Now doesn’t work *2021-10-11, version 2.0.9* Was a decent app but has wiped all my data and stopped monitoring my sleep. Looks ok until I click stop and then it dies. Such a shame as it’s been great for months! ### 3/5 — Good in principle *2021-03-07, version 2.0.8* A good app, but power hungry hence having to keep your phone on charge all night & consumes a lot of storage with no way of easily refreshing the data capture it to minimise its impact. ### 4/5 — Overall great but...... *2020-12-16, version 2.0.7* Clever and mostly accurate, but there some annoying errors. For example last night I was in bed for over 8 hours and it was rated as ok. The previous night I was in bed for just under 8 hours and it was rated good. The trends section shows that on one occasion about five weeks ago that I went to bed at 2pm, which is nonsense, I went to bed at almost 11. ### 3/5 — Good but *2020-09-17, version 2.0.7* Good app but it does not allow for the following Naps I take during the day Does not let me listen to my books when on Can not play music to relax, yes it offers music to assist with sleeping. I’d like to see some changes ### 2/5 — Keeps crashing *2020-06-05, version 2.0.7* I like the app but it keeps freezing and crashing. Plz fix ### 3/5 — Works well apart from battery drain on watch *2019-11-21, version 2.0.2* Would have given five stars if it didn’t drain my Apple Watch 4 from full charge to empty in 2 hours. ### 3/5 — App broken *2019-11-05, version 2.0.1* After the latest app update the app doesn't show any sleep results. It looks like it tracks during the night but when you stop the tracking in the morning the graph is blank. Please fix as before the last update it worked great. I'm on the latest ios as well ### 2/5 — Apple watch app doesn’t work *2019-10-27, version 2.0.0* This app is good for measuring the type of sleeper you are. And encouraging you to get 8 hours of sleep. But only if you use the phone and not an apple watch. I find that the apple watch does not sync with the phone app. So I have no sleep recorded. Also it uses my whole battery life in one night. ### 3/5 — Could be better! *2019-10-15, version 1.1.8 (1)* Was good to start off with and saved my data all the time, but now when I wake up it tells me everything it should then when I go back on the app of a night to start tracking all the data from the night before has gone. ### 3/5 — Great app but buggy since update *2019-10-14, version 1.1.8 (1)* I really want to rate this high because my first couple of weeks using it were great, but for some reason since it has been updated, it’s gone wrong! The first update since I got it caused the sleep tracking to crash out of the app. This was remedied in a second update, but now it doesn’t seem to save my sleep? I can see the night when I first stop the recording, and until I scroll across to see a previous day, but once I go back there is no data! Where did it go?! ### 3/5 — Looks like a great app, fatal bugs *2019-10-13, version 1.1.8 (1)* The app itself is great and gives good insights but each night I record by the end of the day the data had disappeared from my account and I have to start again. When will a fix for this bug arrive? ### 3/5 — App not recording sleep *2019-10-12, version 1.1.8 (1)* App used to work wonderfully until my phone updated and it stopped recording the data. Tried uninstalling and installing the newest version but it still doesn’t log the data- it’s there when I first look at the screen then it disappears and isn’t logged. The app itself before this is BRILLIANT!! ## Most critical reviews (10 lowest-rated) ### 1/5 — Cannot even login with apple!! *2023-02-04, version 4.0.3* Trying to logging validating with my Apple ID and getting an error!! So cannot even login!!! Great app!! ### 1/5 — Absolutely rubbish after update *2022-04-13, version 3.0.0* Crashes constantly, The new app doesn’t seem as flexible as the old. I can’t set what time I want to wake up and seems to change dynamically and find this really confusing and means I have to go into it every night to make sure I wake up at the correct time. ### 1/5 — Mick *2021-02-13, version 2.0.8* Not opening, stopped working, tap on app goes to start then returns to app! ### 1/5 — Riddled with bugs *2020-01-30, version 2.0.5* Riddled with bugs to the extent it’s unusable. Such a pity because the concept is good. ### 1/5 — Not good *2020-01-24, version 2.0.5* App will not load - keeps crashing. It also has not written a weeks data to Apple Health app even though I set it up to do just that. ### 1/5 — Crashes every night *2020-01-11, version 2.0.4 (6)* I did not even have a chance to test this app because it crashes during the night. So annoying... ### 1/5 — Battery apple watch Dead! *2020-01-02, version 2.0.4 (6)* I can't use this app because the apple watch battery dies during the night while using the Simba app. This is the third time that happens. Can you fix it please? ### 1/5 — Oh no it’s got worse! *2019-11-08, version 2.0.1* Sorry I won’t be using this anymore.. the alarm didn’t go off and instead of waking up at 6.30, I woke up at 8.15!! 2 hours late for work, my boss wasn’t best pleased.. I did have a great nights sleep though- even though the app didn’t record it... ### 1/5 — Data *2019-11-06, version 2.0.1* It seemed good to start but some days it does not keep your data, it disappears. Shame ### 1/5 — Great idea... *2019-10-17, version 1.1.9 (1)* Nice idea, but after using it for the first night and viewing my sleep analysis the data has disappeared. For a sleep tracking app this is a major bug. What’s the point if it doesn’t save the data so I can see averages etc.... ## Most praised reviews (10 highest-rated) ### 5/5 — This app will help you sleep like a baby *2024-02-27, version 4.3.6* I've always had a bit of difficultly keeping track of the quality of my sleep. In terms of managing time, it really becomes the first thing on the chopping block when it comes to making sacrifices when it really shouldn't be! (which is almost encouraged with a culture that puts 'productivity' on a pedestal above all else) Getting the right sleep is highly important and Simba has done a fantastic job in educating me around sleep and sleeping habits in general via the app. There's a lot of false information out there, and this app cuts right through that. Saying that, the app isn't going to do the work for you nor can it. Some effort is required for the best results!! ### 5/5 — Loving the app *2024-01-10, version 4.3.4* This app isn't just about tracking your sleep but your energy levels; You can learn what is affecting your sleep quality and look at sleep as a whole. I had no idea what bad habits I had before using the app. And also the app has a lot of tips and tricks that are based on science. Proper expert advice. They have made me rethink how can I rearrange my bedroom to improve my sleep. Those are some really useful tips that you don’t see from other sleep tracking apps and do guide you to sleep better. ### 5/5 — Super Easy to Use! *2024-01-08, version 4.3.4* This app is the sleep tracker app I never knew I needed. Super easy to use, syncs up with my other health stuff - we're talking fitness trackers, the whole squad. It also has a cool alarm function. And can we talk about the bite sized sleep modules? It really allows me to learn about my sleep and understand what bedtime habits are impacting my sleep. If you're not using this app, you're basically missing out. Highly recommend, 10/10! ### 5/5 — Works like a dream! *2020-11-27, version 2.0.7* Fantastic app, great sleep analysis. ### 5/5 — Not working since update! *2019-11-06, version 2.0.1* Loved this app but Since the update all I get is the lady holding the moon :( ### 5/5 — Just what I’ve been looking for *2019-10-21, version 2.0.0* I’m not a great sleeper by any means and have used sleep trackers for a while. But nothing that I feel is specifically tailored to the way I sleep and definitely nothing that has helped to improve the quality of my sleep. Simba has offered tips and sleep notes have helped me to almost self-diagnose areas for improvement. My length and quality of sleep has improved greatly and I feel much healthier for it. There have been a couple of bugs which is not ideal, but these were patched pretty much immediately so didn’t impact my results. ### 5/5 — Best sleep app ever! *2019-10-10, version 1.1.8 (1)* So glad I found this app. It’s given me a real insight into my sleep pattern and helped me form a much more positive sleep routine. A good nights sleep makes such a difference to my day and my wellbeing, and now I can track it I feel like it’s getting better and better! ### 5/5 — I love this app, but a major glitch is making it useless. *2019-10-02, version 1.1.7 (1)* Dear Simba, I love your brand, your beds and this app. You just showed to me how you care about your products and customers but responding to me and fixing the app. I’ll give it a go tonight! ### 5/5 — Great App and very accurate *2019-09-06, version 1.1.4* Tracks my sleep very accurately since I have started using it ### 5/5 — Great app *2019-08-29, version 1.1.4* Perfect app to track my sleep. It also gives tips which has helped to improve my sleep quality!! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
