Fix it or remove it from the store. ### 1/5 — Why dose this exist? *2022-11-07, version 1.33* Why? What is the point of this app? There is nothing you can’t implement in one main app. You don’t need an extra app for everything. Just build one good app. ### 1/5 — It doesn’t work *2022-09-19, version 1.33* The app doesn’t work. While trying to make a purchase, it says that there is no transactions pending. Well, there are some! ### 1/5 — Unacceptable *2022-04-03, version 1.33* I lost my time and got anxious for no reason ### 1/5 — Not working *2022-02-15, version 1.33* Tried to use it with the cosmote app and it does not work! ### 1/5 — The worst app ever *2021-11-23, version 1.33* No reason for this app .The worst app ever! not working ### 1/5 — Not a good app *2021-10-16, version 1.33* Guys come on. Fix the app. It should be easy enough. When it works it is great. ### 1/5 — Fail *2021-10-12, version 1.33* Best secure for your cards ! Because no payment ever worked .... ### 1/5 — iPhone XR does not have fingerprint sensor *2021-07-30, version 1.26* As a result, the app is waiting forever in the fingerprint registration page. Unacceptable bug! In addition, I do not have enabled Face ID not even planning to do it. My authentication method is PIN and I expect your app to respect it and work with it. Please respect your clients and provide an application that works! One star is high review rate for such a low quality app! ### 1/5 — Terrible interface. *2021-07-25, version 1.26* As usual with NBG everything is far harder and more complicated and DOES NOT WORK. EXTREMELY FRUSTRATING. Crap app for a Crap bank. ### 1/5 — Does not work *2021-07-13, version 1.26* Does not work ## Most critical reviews (10 lowest-rated) ### 1/5 — Don’t Work *2025-07-07, version 1.40.4* The doesn’t work! Actually doesn’t start! Uninstalled it and installed again but the problem remains ! Loading for ever! ### 1/5 — Non working app *2025-07-06, version 1.40.4* The app is simply not working for days now. For such a critical app to be non working for several days and keep users blocked is unbelievable these days. One can understand how this bank operates and how it values its’ customers. And yes some customers have not NBG internet banking but only a Visa card that need only the NBG Authenticator. Such a disappointment. A good chance to apply on a new card on another bank. ### 1/5 — doesn’t work *2025-07-05, version 1.40.4* almost never works what am i even supposed to do ### 1/5 — Notifications issue *2025-06-16, version 1.40.4* While i have on all notifications, never get any, i have to log in to app to see the pwnding transaction, fix it, its 2025! ### 1/5 — Stopped working *2025-05-04, version 1.40.4* Message “something went wrong”. Cannot enter the app since reinstalled ### 1/5 — Problematic *2025-05-04, version 1.40.4* Doesn’t work any more ### 1/5 — Crush *2025-04-29, version 1.40.4* The app has crushed and even open ### 1/5 — Bull S… *2025-04-28, version 1.40.4* F… o… ### 1/5 — Technical problem to access *2025-04-27, version 1.40.4* On the place of terms and contortions when I press the accept button doesn’t work so I cannot use it ### 1/5 — Hacked *2024-02-21, version 1.35.1* I just got hacked and they spend 81 dollars and this app is supposted to prevent any purchases , only after i view them right? Well i guess not.. ## Most praised reviews (6 highest-rated) ### 5/5 — Very good I recommend it had no problem with my order *2021-04-19, version 1.6* It’s something new you just have to have fingerprin on yours phone ### 3/5 — Problem showed up using this mobile app after getting the last update on iphone mini 12 *2025-07-06, version 1.40.4* Since yesterday I cannot complete any payment bc I am constantly getting the error “Oops! Something went wrong! Please try again later” in greek language (but this does not matter)! ### 3/5 — Cant log in *2025-07-05, version 1.40.4* The apps is not working for 24hrs now ### 3/5 — Doesn’t work on my phone, but signing on the website works *2021-08-09, version 1.33* I guess my iPhone is an old version and the Authenticator app doesn’t work for me. On my daughters newer iPhone, it works. But at least they’ve created an option to authenticate purchases when you sign in to the actual website. So that’s good. But I still wish it was easier to purchase stuff. Many times, I just use my USA credit card, PayPal, or select αντικαταβολή just to make the purchase faster. ### 2/5 — Problems *2025-05-02, version 1.40.4* This Bank has a prepaid virtual card which has no authorization to deposit include in in the Authenticator. Secondly the app sometimes stops working so uninstall and install is something extremely inconvenient to do ### 2/5 — Not for prepaid cards? *2021-04-29, version 1.17* Prepaid (virtual) cards do not have a PIN, as far as I know. Therefore not possible to login. Maybe the online vendor should not be requesting this form of authentication for virtual cards? Same vendor, on other occasions, does not request approval through the Authenticator. Also, the identity check page does not offer the alternative methods mentioned. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
