Navamsa Chart calculator

Dear Astrologers,

Where can I find a correct Navamsa Chart calculator?
I found some on the internet, but every calculator showed different charts, so I get confused a little bit.

And what if Navamsa chart will show a better marriage than Lagna Chart? Which will say the truth?

Regards, Christine

The Vargas can only confirm or modify what is indicated in the Rasi, so the Rasi will have the last word.

Yup yup. ☺️

Thank you very much
