anglais I find CMB to be the best French bank by far and, since I live in a very remote area, this app is a really useful facility for when I can't get to see my counsellor in person. CMB is a human bank with real, skilled people working in it, they are creating solutions for all their clients' banking needs. I am very happy with it. full marks for CMB ! Français je trouve la Banque CMB le meilleur de ceux que j'ai essayé et cet appli le rend davantage utile. je suis très satisfaite !

does the job, but too many menus on the screen, in a landing screen I expect to see all my accounts at a glance (savings, main account..), looks like the space is not used effectively. In the other hand, it has some very handy expenses filters to allow exact tracking of your money in out flows

So long to open the app, sometimes 2 mins. Useless for overseas clients as you need a QR code they send to your house, in France! No option to send by email. Then the only other option is to log in via the website, which defeats the purpose of the app. So, as a result this app is useless to me. I thought I would give it one more chance with the update, but NO, still the same.
