ive done some very limited scans with android and windows 10. what i found was the phone seemed to loose track less and was smoother. this seems very counter intuitive. one limit i the mobile app had when i used it was it can only scan till the phones memory is full.
No you don’t , the pitch point setting is lower and meshing even more lower than traditionally on your computer for an obvious reason, phones are not yet fast enough and the processing time would be enormous.
And as Jeff already stated , memory limitations also plays here a huge role.
