I want to be updated when my students send me emails, but since I dont hear any sound or ringtone and I cannot constantly look in my cellphone, it is time consuming to keep opening my canvas app. Please help me get a ringtone.
I can't understand your question yet. The ringtone will be set only for mobile devices. I have not seen any onl application that can install ringtones. Try searching for some attractive ringtones in the market today.
Some websites offer quite attractive ringtones for iPhone such as https://zigtone.com/iphone/. You can go there and install it on your device.
