I am not sure if you are going regularly or occasionally to Casinos for playing slot machine games. if your answer is yes , you definetely need this application.
You can enter and check all necessary informations on one simple screen.
You need to enter wallet to pocket transfer to see how much money you had at the beginning.
Also, You need to enter all money in-out transactions, also winning ticket or loosing money transactions.
After every transaction entry application will calculate and show you how much you are winning/loosing after that.
You will be pleased to check , how much money/tickets should be in your pocket without checking your pocket in the middle of Casino.
Also, this application may help you to see how much you are spending in 5-10 minutes.
It is worth to try.
