Let's say I have multiple (N) wallets, with N public addresses and N private addresses. Is there a simple way to track the balance (and transactions, but this is not so important) of those wallets? Ideally I would install an android app with the capability of adding public addresses that allows me to see the balance of those addresses.
I do not need to be able to spend from those wallets, just to be able to see the balance. That is, I do not need to import the private addresses, just the public ones.
