Tarp is plastic and will break down over time. For that reason alone I'd never use it.

I always used the official app because I couldn't be bothered. Still stopped using it because I won't support this shit.

I also don't miss the ragebait and troll posts, those can stay on reddit.

As the others have said, most plants might tolerate low light but don't really thrive in it, it completely depends on how dark your bathroom really is. That said, in my place the plant that dealed with little light far away from windows the best was a Spatiphyllum/peace lily.

I always wanted to try lemongrass, maybe that could be interesting for you as well?
