This app is so good

This app is amazing. It's helped me make so many friends. When I wake up, I grab my phone, and turn on this app. With my windows open and the beautiful morning light shining in, I gain the knowledge of whether it is dark outside or not. I then go to the school, and tell all my friends the findings. They say things like "Go away" and "I'm not your friend!" But those are merely words of acceptance, and friendship. I feel, that with this amazing app, not only am I enlightened with the information of light or dark, I am a relevant part of society. When I am basking in the sunlight, I feel amazed by my the feeling of get getting my phone, turning on this app, and find out if is dark outside. I have faithful memories of gaining information with this app. With this app, I feel no need to go to school, because of the knowledge it provides me. When at the school, the Trying to share the amazing knowledge this app provides, I find that kids are saying "weirdo" and other similar things. I feel honored to be entrusted with such gratitude. My life is complete. I love this app.

A designing marvel

This app in no way disappointed me, as it really couldn't have. It advertises that it will tell you whether or not it is dark and it does that with remarkable accuracy. Ive had the app for a few days now and it has not once been wrong. Ive even had the app open while watching the sun set to see exactly when it changed from no to yes, which it did right on schedule. There are no extra bells and whistles that take away from the app's original founding idea. It's a common idea among engineers and designers: the more complicated something is, the more possible problems there can be. This app is quintessentially as simple as it can possibly be, so really only one thing can imaginably ever go wrong, and since the creators only have to focus on that one thing, it virtually never happens. This app did not make me laugh; I did not download it as a joke. In seriousness, this is undeniably a well built app that works as advertised better than any app I've ever seen.

My life now.

Well to first off start this review I would like to explain how I now have split my life time. It is almost like the conventional system of B.C and B.C.E. And yes I am comparing the birth of Christ to the app. So This is how I have split my life B.I.I.D.O.(before is it dark outside) and A.I.I.D.O.(after is it dark outside). Yes it has really changed my life that much. I know my place in this world. I am no longer a slave to the old human hassle of being unable to determine if it is dark outside. It has all changed. I can now actually know if it is dark, I can define dark... I am dark, except when it's light. So when the average man asks me if I should download this app, I say a simple "yes". As not to confuse this person who's mental capacity is being taken up by determining if it is light or dark, I don't want to startle them. There mind will be free now because of this app and the true meaning of life can be reached.
