Some bad moments

Это лучший калькулятор для iPhone, замену которому я уже долго ищу. Он очень удобен записью истории и нормальной работой со скобками. НО, дизайн никак не может прийти в соответчик с iOS. Иконка, отображающаяся в AppStore выглядит на iPhone иначе! Почему никак не исправите эту ошибку? Уберите из названия глупую точку после слова "калькулятор". После обновления иконки и названия, я буду готов выражать благодарности бесконечно. This is the best calculator for iPhone, replacement which I have been long looking for. It is very convenient to record the history and normal work with brackets. BUT, the design does not can come in a co-defendant with iOS. The icon that appears in the AppStore looks on the iPhone otherwise! Why not fix this error? Remove from the title of a silly point after the word "calculator". After updating the icons and names, Im ready to Express my gratitude forever.
This app is garbage and its not what you see in the screenshots its very misleading and a waste...
My favorite part is that it has your calculations to the left so you can check to see if you missed anything.
Love this calculator. The only thing I can suggest would be to add more backgrounds to choose from .
I have been looking for a calculator app that has both the Percentage Sign and the Memory Recall button front and center and this is it! At $.99, best value for the money! Thank You!
I tried using other calculator apps and theyre just not that good. The app that comes on the iPhone is a joke. Are used this app most often and its the most dependable.
