Sensibull alternative for US Market (SP500 Options)

General
1

I found Sensibull very useful for options trading (strategy building / monitoring etc) in Indian market.
Is there any such tool for SP500 Options (US Market) that NRIs can use?

I tried the one provided by a broker (Interactive Broker), but its really bad compared to Sensibull.

Could be we are used to Sensibull. IB and thinkandswim option analysis is far superior.
