Good morning, echoing a number of the suggestions here.
Firstly the junior card is a great idea, have ordered one for my daughter and she is very excited to receive it.
I understand the limitations of it being linked only to the one parent and I get that it does not have its own bank account or IBAN that family or friends can send money to but surely it is not too difficult to at least have a custom message that I can attach to each transaction. At the moment it just says from <>. I cannot even put from dad on it. It was her birthday recently and different family members sent her money. I cannot even add from Grandma or from Uncle Tom for example. This would be such a simple but yet massively beneficial feature. You can easily add a reference when making payment using the standard Revolut account.
The other main thing for me which has again been mentioned a few times is the currency exchange limitation. We live in Gibraltar but spend a lot of weekends in Spain. I get that any purchase in Spain she makes will have the appropriate conversion made but she should be able to do that herself. This was one of the main features that made me sign up to Revolut myself in the first place. She has just been learning about money and different currencies in school as well so this would also really help the learning experience.
Otherwise looking forward to the future updates. Hopefully the Junior app will receive the constant updates and improved features we are lucky to receive in the main app.
