Useful, use it every day

If you are one of those people that have a crud time in the morning, aka me, this is a great little app. Customizable settings, easy to use, takes two seconds to check, saves you a load of time when you wake up. If you want to get back into good sleeping habits, give this a go. Only thing, you have to pay to use the alarm function setting in the app, but if you dont want to, you can use the alarm app that comes with ios. No problems, works the same way.
