Ratings and reviews

My friend had to send a payment to me but he mistakenly sent it to the wrong number, the number in question wasn't yet subscribed to the application. Unfortunately Lydia doesn't enable you to cancel a payment (even if the receiver doesn't have an account!!). So the mistaken receiver could receive a kind invitation to subscribe and take my money!! I am very disappointed by that lack of security

I've had a great experience with this online bank. The app is easy to use, transfers are fast, and managing my account is simple and convenient. Customer support has always been responsive and helpful whenever I needed assistance. The fees are reasonable, and everything can be done from home without needing to visit a branch. I highly recommend this bank to anyone looking for a modern and reliable banking experience.

Crash and redirect to a KB saying it doesn't allow Root/Jailbreak when I'm literally on OneUI 8.5 stock from my A55 device. Can't even keep my account active and can't connect to web without it asking for a code in the broken app.

What’s new

The app home screen has been improved: each account now always displays the Sumeria card it's linked to, and the action button for sending money is now always visible in the bottom right-hand corner of the screen. Tapping it prompts a choice between "Lydia payment" and "Wire transfer" with a new animation.
