Is it safe to check a checking account balance from a phone?

Retrieving a checking account balance by logging into a web site or using a mobile banking app is as safe as checking it on a computer. In 2014, Bankrate reported that It may be more secure to use a bank's mobile app because of proprietary security measures.

To keep banking information secure on a phone, make sure the bank has a way of recognizing the specific phone or phones linked to the account. In 2014, Naked Security reported that 70% of the mobile banking apps they tested did not support such two-step authentication. This second step prevents someone from accessing an account from a different phone, even if they have a user name and password.
