Count Guru

"Count, my friend, count!" – said one wise man and Count Guru will help you with that! It's an antidote to calculator. Summarise, subtract, multiply and divide! Yeah, you can do it! The app remembers your answers to questions and does not offer you the questions you have already learned. Wounderful, isn't it? ^-^ Our app will be updated further to train you better! Please write your comments, feedback is important to us!
