Instagram viewing - can people see if you are viewing them?

If friends have an instagram account but I don't have an iPhone/smart phone and can't open my own account, can I view their photos? Also, can they see that I'm viewing their photos? How about through third party sites like webstagram, statigram, etc?

Nope No Way to Find Out Who Views Who's Instagram The Only Way would be If you Liked There Photo or Follow them than they will Know but other Than That No
