In the old days, people had to buy a separate alarm clock if they needed to wake themselves up early in the morning. But thanks to advancements in technology, most smartphones nowadays have a built-in alarm clock eliminating the need to buy a separate one.

However, built-in alarm clock software has their fair share of limitations. If you want a fail-proof clock to wake you up on time, this application is a great option for you.

It has great sensor features where you can simply flip your phone over to snooze the alarm for a few minutes.

It also has a speaking mode where a voice will tell you exactly what time it is.
