  18. [R61] 5/5 · US Mobil check deposit!: So glad you added this feature!
  19. [R62] 4/5 · US Easy to use: I’m pleased SFCU has added the electronic deposit option. It is now equal to the other bank apps.
  20. [R6] 3/5 · US Mobile deposit is broken: This is a great app. Two stars are taken away because I cannot do mobile deposit on checks anymore. I get an error message.
  21. [R93] 3/5 · US No Mobile Deposit Feature: When is mobile deposit going to be available?
  22. [R45] 1/5 · US Uploading pay checks: There’s always a lagging problem and I’m always booted off the app when I’m trying to deposit my pay check you guys should really take time to fix the app
  23. [R9] 1/5 · US Nice job: I’m stuck in California cause i can’t Zelle money cause it just feels like declining it and I can’t move money to cash app or any other money movement app for some reason also can’t reach an operator been trying for two days now. If you join sfcu good luck.
  24. [R14] 1/5 · US Lazy: This app has poor layout, hard to find features and insufficient responses and functions of the support chat. It’s been impossible to set up Zelle even tho it’s advertised as being quick and easy. The website lists functions that are supposed to be in the app that aren’t visible on the actual app at all. Unnecessarily confusing and annoying, and this is coming from a 25 year old lol. I wish
  25. [R18] 1/5 · US App generally does not work: This app intermittently works, if at all. After it logs you in, which takes about 10 minutes, it won’t let you see your accounts. The screen stays blank. I would recommend just going online through the website if you need access.
  26. [R42] 1/5 · US App Crashing: I love the people at SFCU. This app has a track record of zero. I have face recognition enabled. I have uninstalled, deleted, and reinstalled the app. I get the same error message: “Something went wrong while attempting to send the last request.”
  27. [R95] 1/5 · US Doesn't work for iPhone: Terrible app - doesn't work for iPhone. It used to, but it doesn't anymore and hasn't for the past month and a half. Every time I call asking when it will be fixed, they just keep saying they're "working on it". Please. I'm considering switching to another bank just because I don't have the convenience factor of being able to check my balance on my phone...I live 10 miles
  28. [R8] 1/5 · US Annoying to sign in: The app stopped saving my username, so I have to type that in every time. Also every time I sign in there’s a pop up reminding me to set up digital ID and I have to click “remind me later”
  29. [R21] 3/5 · US It’s okay..: I was told by an employees at the bank that I could lock my card, but I do not see an option anywhere on the app. I would rather feel safe while I’m not using my card knowing it’s locked and cannot be charged
  30. [R99] 3/5 · US Decent app: Wish it had push notifications for things like upcoming payments.
  31. [R101] 3/5 · US Almost Good: I share a fellow reviewer's frustration at not being able to link accounts.
  32. [R100] 1/5 · US Lame app - not worth the download: You can't link accounts - lame. Then the app rendered itself useless & wouldn't recognize my "identity" claiming some kind of error (theirs not mine). A vast improvement from the mobile site, which is not saying much. If you're "ok" with mediocrity - this is the app for "u". A complete waste of my time. Already deleted.
  33. [R10] 1/5 · US App: I just recently got a car loan through this bank and trying to figure out how to make a payment online is impossible. It keeps telling me it can’t find my account but bet it would be able to if I missed a payment. Clicked on the chat icon and NOBODY was available to help me. First time interacting with this bank. So far I’m not impressed
  34. [R79] 5/5 · US Great app! Use it daily!: The one thing that could make it better is the virtual check deposit.
  35. [R57] 5/5 · US Essential: I appreciate the security and ease with which I can do banking and pay my bills no matter where I am. I can make use of time that would otherwise be wasted.
  36. [R102] 5/5 · US Linking accounts: I don't like the fact that I can't link my accounts in this app. Otherwise I guess it's ok.
