Too simple
Response from developer
Thank you very much for downloading and for your valuable review. Your comment will be considered for future development. For your reference, this app was developed with the desire that many people would like to use it easily. For example, when go to shopping and find a product for 987 yen for 3 pieces and 1245 yen for 4 pieces while shopping, this App would be able to calculate "Which is cheaper? ","How much cheaper" easily. (Details please see https://twincalc.jp/en/ ) Therefore, so far this app does not have complicated functions like scientific calculation. If you need to do complex scientific calculations, please use the preinstalled calculator App in your iPhone with landscape mode.
Works great. Please add support for portrait orientation.
