### 1/5 — Latest version doesn’t work

*2026-05-24, version 4021.0.2*

After installing app it forced me to reset my password for some reason. Entered my info and kept getting an error message that my info couldn’t be found.  I have an account, also have the app on my android phone and it works with no issues.  Not sure what the problem is with the apple version of the app.

### 5/5 — Love the MEFCU App!

*2026-02-17*

The MEFCU app makes mobile banking incredibly easy, convenient & helpful. Just the right amount of protective features and the ability to remote deposit checks or make payment transfers in seconds is much appreciated.

### 5/5 — Glen

*2026-02-14*

I love you dearly, MEFCU.

Happy Valentine’s Day.

### 4/5 — Works fine..

*2025-10-08*

No complaints other than please add a dark mode option.

### 5/5 — Faster

*2024-04-09*

I’ll redo my review…after the first few days, it’s much faster. Potentially even faster than the old app. So I’m back to 5 stars.

**Developer response:** Thank you!

### 3/5 — New Rollout is Slow

*2024-04-04*

The new update does provide a sleeker interface, but everything is so slow now I don’t want to open the app anymore

### 5/5 — New version is very slow

*2024-04-04*

I use the mobile app routinely; after the upgrade this past weekend the app has become excruciatingly slow, the ability to call from the home page is gone; can’t seem to find the instant balance feature (maybe it’s gone?) and on and on. I appreciate MEFCU’s attention to security, wish it didn’t come at the expense of convenience

### 3/5 — Needs work…

*2024-04-02*

The app appears more sluggish than the previous version. Wound up setting things up in the browser version and then things worked okay in the mobile version. Can you please offer dark mode for BOTH browser and mobile.

### 1/5 — Slow!!

*2024-04-02*

This new app is painfully slow. Everything takes forever to load. The old app was so much faster. This app has become useless.

### 3/5 — Needs work…

*2024-04-01*

The app appears more sluggish than previously. Text authentication doesn’t appear to be working. Bill pay… is it opening to some other window we cannot see on mobile? Also, can you please offer dark mode.
