You're definitely not alone. I just checked the list of installed apps on my phone and found three different banking apps that I completely forgot about because I never use them. I installed them because I thought it would be convenient for checking things on the go, but I actually just end up using the computer whenever I need to do real banking business. The only finance-related app I use with any regularity is Venmo for e.g. paying back a friend for covering dinner.

Another commenter mentioned needing to get alerts for fraud, but none of the financial institutions i'm currently doing business with have any trouble sending me text messages. In fact I have the opposite problem, I can't get them to stop using text for 2FA codes...
