  1. [R54] Coastal Credit Union 5/5 · US New app UI: Coastal is a great bank, however; with the new app update they have really upped their game. Between easy external account transfers and Zelle they are now on the same level as any major bank like chase or BOFA.
  2. [R3] Coastal Credit Union 3/5 · US Good news, bad news: Good news: Coastal Credit Union is a great institution and the iPad app finally works in landscape orientation. Bad news: Since some update to the app or iOS, bill pay can’t be completed in the app, so it’s just a convenient way to check your balances. This glitch also affects the Mac laptop. Why?
  3. [R63] Suncoast SunMobile 3/5 · US We Need Zelle!!: I mean what else does this bank need? 🤷🏾‍♂️ It’s great. But I am suffering without Zelle
  4. [R66] Suncoast SunMobile 3/5 · US Transfers Don’t Work Now.: This used to be the best app for banking. It has been updated and now you cannot use the transfer feature. Please fix. Thank you
  5. [R20] Coastal Credit Union 5/5 · US App is very user friendly: Well made app. Safe and efficient.
  6. [R12] Coastal Credit Union 3/5 · US Bank is great, app is wonky most days: The bank and stag are great. The app is hit or miss and sometimes features don’t work consistently
  7. [R67] Suncoast SunMobile 1/5 · US Won’t allow me to log in,: Been having an issue with the app for the passed two weeks.. Called customer service, and got no where. I can log in perfectly find on my PC, but not with my app. Tried deleting and reinstalling the app numerous times, updated my phone and still having issues. Please help, I frequently use this app..
  8. [R90] Suncoast SunMobile 3/5 · US Great when it works: Seems like every time I try to login it takes 3-4 attempts to get into the account if it ever logs in at all. Please get this fixed.
  9. [R1] Coastal Credit Union 1/5 · US Unreliable: Sometimes the app works like you would expect an app to work in 2026. Most of the time it works like dialup. I’ll tap on something to access it and I wonder if my phone has frozen or locked up. If I tap on my checking account to see transactions, it can take up to 15 seconds for it to open.
  10. [R100] Suncoast SunMobile 1/5 · US Terrible app: The app never lets me log in. I can only log in online but when I try to use the app it does not work it’s absolute trash
  11. [R58] Coastal Credit Union 5/5 · US Online banking: The experience is always pleasant. The best decision o ever made was open an account with Coastal Credit no hidden fees and always taking care of the customers.
  12. [R113] Suncoast SunMobile 5/5 · US Awesome bank that you can trust: Awesome bank that you can trust with your finances. No fees or surprise charges.
  13. [R4] Coastal Credit Union 1/5 · US App needs a rework: Have been a Coastal member since 2003. Unfortunately the last year of using the app has presented some issues from an end user perspective. How does one reset the password? This is basic functionality that does not exist in the app. One is prompted to call customer service which is not available in the evenings or on weekends. We have been locked out of our account for two d
  14. [R23] Coastal Credit Union 5/5 · US Great app: Great app after you figure things out and you can always call customer support.
  15. [R79] Suncoast SunMobile 1/5 · US Very poor: Very poor application and system implementation by Suncoast. They recently transitioned to a new app, and with that update they disrupted the functionality of my credit card payments. My transactions no longer appear, the real balance of my card is not reflected, and recent activity is missing. At the branch they blame the system, but if on my credit card due date I’m unable to make a p
  16. [R15] Coastal Credit Union 3/5 · US Mobile deposits: I love working with Coastal and the fact that it’s not one of these huge national for profit banks. However, their mobile app leaves much to be desired, particularly when it comes to depositing a check. Over the course of several different, smart phones with increasingly better cameras, the check capture photography often times does not work to the point of frustration. Need to ge
  17. [R61] Suncoast SunMobile 2/5 · US Can’t deposit a check: Ever since the authentication was implemented (via text or email), depositing a check has become a time-consuming process. It takes me on average 3 attempts to get this done. I might as well go to the bank in person.
  18. [R82] Suncoast SunMobile 1/5 · US Mobile deposit not working: Trying to make a mobile deposit and get the authentication text, hit submit, and the wheel just spins. I’m not local so this is very frustrating.
