I'm recently searching for simple application to control my bills, without any not used features. I found and use this application: https://play.google.com/store/apps/details?id=com.synapsis.fcalc that is pretty nice and most important thing is that you could request a feature.
Application have a lot useful features but the most important is Bills Manager. Everyone has bills to pay and managing all your bills isn’t an easy task. Application lets you easily control and manage all your bills in one simple, secure place. You don't have to remember payment dates because of automatic notifications of upcoming bills for both one-time payments as well as recurring bills. All paid bills are recorded for future reference.
You could analyze your monthly bills per category. Very nice, simple and very often updated application. Every update give new experience.
