Sleeping so much better since using the app!

I’ve tried various sleep apps to help me improve my sleep (and overall health) and I have to say that the Simba Sleep app had by far the biggest and most positive impact. Sleep tracking is so easy as I don’t have to wear any devices and the sleep performance insights are super useful. Discovering my sleep persona helped me improve my lifestyle in various other areas and I’m sleeping so much better since using the app....the app has genuinely revolutionised my sleep life!

Easy to use but...

Two things about the app:
Your screen is ‘on’ all night - hence the instruction to leave it face down. I’m not sure this is good for the phone if used every day over a long period
The results look ok but don’t agree at all with the sleep patterns I get on my FitBit. How can the Simba app detect who it is monitoring if there are two people (or a human plus dog) in the bed?
The menu to set it going isn’t very straightforward- you find it under ‘alarm’ whereas a link under ‘monitor’ would be better. When you do find it, you have to touch ‘start tracking’ on two pages before it begins monitoring, which is confusing.
Overall it’s a good idea but needs fine tuning abc I’d like to see its performance compared to other sleep trackers

Developer Response ,

Hey cmc575,

Thank you so much for your review. We're constantly working on improving the app so your feedback is very valuable to us.

In regards to the screen, you definitely don't have to keep it 'on' all night, we even recommend that you don't. You can lock your screen or even exit the app and tracking will continue to work in the background without a problem. If you have screen auto-lock enabled on your phone, it will lock automatically after a while depending on your settings.

We're also currently working on full integration with Fitbit and other wearable devices, which should help with your tracking. One thing to note is that Fitbit, Apple Watch etc. track your movement and motion, where as the app primarily relies on sound analysis, so results can vary slightly. Once the integration is complete, we'll be able to overlay your motion data with the sound analysis to give you even more accurate results.

We'll keep you posted on progress and please don't hesitate to share any further feedback with us via

Slick, simple, great to use

I’m new to sleep tracking but already benefiting from knowing how I sleep and using the insight to really get the best of a good nights sleep.

I’ve tried pillow but the graphics and navigation are a bit clunky, this Simba sleep app is far easier to both use and understand!
