Native side by side app without root...

It's a shame that till today there are no simple app can double the screen for stereoscopic mode for all the apps.
Would be so simple to include this option...
The only way till now is native sbs apk for android but work just for some rooted phone and you always need to reboot the phone...
Would be so simple this option why is not possible for people without root ?
