I have been using the Motilal oswals mobile app for Stock Trading.
My experience for the app is so far been a mixed bag.
The stock suggestions provided by them are inaccurate and highly volatile so I advise you to not to follow it blindly without having a script.
The biggest advantage is that you can trade at the convenience of your home, just you need to get registered at their brokerage house.
FNO trading is also quite convenient and takes a little time.
