Visit the ethstats website to check last block number, and compare it with the block you are syncing on your machine. Once they are the same, you know your client is synced.
Blockchain explorer
...
Blockchain explorer is a very useful tool to monitor live activity on the Ethereum network. The explorer serves as an interface to navigate the Ethereum network, offering high consumability and access to detailed contract and transaction data.
Its main functions allow you to watch real time status of blocks, transactions, smart contracts, as well as many more market statistics. It might help you to diagnose any possible problems when you are sending some coins or should be receiving them.
Explorers
As of 2016-06-22, four blockachain explorers are available on line:
- Etherscan | Etherscan API
They support both GET/POST requests and a rate limit of 300 request/min or 5 requests/sec.
Etherscan also offers a very convenient function: If you register at the site, you can watch your personal accounts and get an email notification if any transaction is recorded involving one of your accounts. - Etherchain

- | The etherchain API
The etherchain API is free to use. If someone abuses the API they will introduce a rate limiting system. The API is still in Beta, they recommend that you do not build applications that fully rely on it. The API endpoint is CORS enabled.
Special feature: You can display the complete program execution of every contract invocation step by step. Very usefull for debugging (if a call to a contract doesn't succeed). - Ether Camp
Ether.camp offers a very elaborate user interface to explore the data structures of a contract. A possible use case for this is checking whether you own a specific token. Just enter the address of the token, then open the balanceOf data structure and search for your accounts address. - Etherscrape
EtherScrape is a complementary block explorer for the Ethereum blockchain, that focuses on program analysis and other sophisticated features. It uses fingerprinting to match each smart contract on the blockchain (that is, the compiled bytecode) to the high-level source code (Serpent and Solidity code on Github, for example) that created it. With this fingerprint search, EtherScrape searches the internet for publicly available Serpent and Solidity source code, most of which is found on Github.
Each site has its own layout and their own style - the choice of which site to use will be very much down to personal preference. In the case of Etherscan & Etherchain they offer their own API.
