https://eostracker.io/ has the best info yet. It shows balance for EOSDAC, ADD, CETOS, EOX tokens. But, it doesn't list all tokens!
To see balance for other tokens, you'll have to dig in deeper with EOS block explorers. First you can find all transactions for your account from http://eosflare.com. You can find transactions for the airdrops. But eosflare.io doesn't show much about the transaction. You'll have to search transaction hash from https://eostracker.io and you'll be able to see the raw transaction which shows how many tokens you got airdropped.
If you can compile or use "cleos" command line interface to EOS blockchain, you can check your balance using following shell script:
API_END_POINT="https://eos.greymass.com"
ACCOUNT="YOUR_ACCOUNT"cleos -u $API_END_POINT get table eosadddddddd $ACCOUNT accounts # ADD
cleos -u $API_END_POINT get table eosdactokens $ACCOUNT accounts # EOSDAC
cleos -u $API_END_POINT get table gyztomjugage $ACCOUNT accounts # CETOS
cleos -u $API_END_POINT get table eoxeoxeoxeox $ACCOUNT accounts # EOX
cleos -u $API_END_POINT get table eosiochaince $ACCOUNT accounts # CET
cleos -u $API_END_POINT get table eosatidiumio $ACCOUNT accounts # ATD
cleos -u $API_END_POINT get table ednazztokens $ACCOUNT accounts # EDNA
cleos -u $API_END_POINT get table therealkarma $ACCOUNT accounts # KARMA
cleos -u $API_END_POINT get table horustokenio $ACCOUNT accounts # HORUS
You can change API end points if it's slow. You can find more endpoints from https://github.com/greymass/eos-voter/blob/master/nodes.md.
I received 7 EOS airdrops.
Please give feedback if you received other Airdrops or found better wallet/site to check all your EOS tokens.
UPDATE:
https://eostracker.io/ and http://eosflare.com have been updated. You can see all your tokens from eostracker.io. eosflare.com transactions now shows how much tokens you got from an airdrop.
There were two more airdrops. HORUS and KARMA.
