i wanted to this myself for my addresses but couldn't find any working application that i could use.
i know of couple of options (not exactly what you want though).
i think it was "shorena" who posted an app in java that you could check the balance of multiple addresses. but you have to replace the API
search the forum for this one or ask him if he remembers.
How do I add addresses to blockchain info's watch only? Don't I need to add the keys for that? And it would be same for electrum I think.
The blockonomics site works but like I said I have to enter the addresses one at a time and it's a pain in the ass to do that with lots of addresses. I'll try and contact shorena for a solution. Thx
bitref doesn't works, I tried adding multiple addresses with + in between them as suggested by them but nothing happens, goochain and duckduckgo, again no way of entering many addresses at once.
I just can't believe there is no apps for this, there are so many block explorers to check balance of an address but none of them have a feature to add addresses in bulk and view their balance.
