Way to buggy

Awful app. Constantly bugs out glitches. Won’t let me in half the time so I have to use their website. It needs fixing asap

Ladybug

White glove service

Great rates!

Would love to see rate you are getting when log in. Great rates so far. Friendly customer service. Would love to see interest rate I am getting in app after log in.

Genuinely the worst bank ever

The app is always crashing and locking me out for days or weeks on end, and whenever I try logging in via browser I’m always told I don’t have an account. It gets to a point guys

Nice bank, nonfunctional app

I haven’t been able to log in via app for AT LEAST 4 months. Prior to that, app would randomly turn off Face ID and require login.

I like the Flagstar Bank, but the lack of investment in their tech - or at least fixing the app since it appears to have broken after the last update (4/2026) is a problem.

Does not Login

The app doesn't work on my IPhone 17. I have tried updating, redownloading, and even asking others for help. Nothing seems to fix the fact that I cannot login at all!

Another outage?

There always seems to be a problem with this app. It’s actually crazy to not give your customers consistent access to view their accounts.

Notes

Note being able to make notes on transfers from account to account makes me want to leave the bank. Why you would take that Way is beyond me. How are we suppse to know what any transfer is for making dozens and dozens of transfers with no notes. Insane.

Great bank

Very professional and friendly and helpful staff. Have been a customer for over 25 years!

Constant

It asks me constantly to review it. I’ve already reviewed it. Quit asking!

Flagstar app

Can’t get into my account for weeks now!!

Constant Bugs and Pain in the Butt

Look, I mostly chose this bank because it's close by and it was once convenient. But now, the app doesn't work, logging on the website doesn't work, and now it's making me run in circles to get anything done. I just want to deposit a check.

GLITCHY

haven’t had luck logging in for months.

App Doesn’t Work

It used to work, but over past month it has stopped working on both my iPad and iPhone 16. I get an error message every time I try to login. Scared me, but I was able to use the website to login, and see that there were no account issues, so just appears to be an issue with the app.

Never works

Flagstar's app has consistently failed to worked over the years. I turn on Face ID every 2 logins because it stops working & my saved password never lets me log in. Half the time the instant balance doesn't work. It only lets me login if I type out my password each time. VERY inconvenient, & always lagging compared to all other banking apps

Zelle not working

My Zelle is not working! Talked with banker. They refused to help me! Any help?

Inconsistent access

The app hasn’t allowed access due to flagstar issues. This happens every few weeks!! Poor design!

FIX IT

Nonstop issues with logging in with this stupid app! I have never in my life change my password so much because this stupid app and bank doesn’t recognize it. Go into a branch and they are even less helpful. I cannot wait to get my money out of this stupid establishment.

Rarely Works

This app works poorly, just like this bank. There is constant log in issues and just directs you to use the website instead. What a waste.
