2017-09-20: SiDiary and iOS11

Unfortunately, we have found out that under iOS11 the specially developed keyboard for entering digits can no longer handle decimal places.
Until we provide an update, you can continue working with the following workaround: please change the settings. Under' More ->Settings ->Keyboard' you can activate the standard keyboard. After that, you will no longer see the keyboard we created when you type, but the normal iOS keyboard.
