Accessible novel writing software similar to Scrivener?

Hi everyone. So recently I haven't been able to open Scrivener projects with VO. I've emailed the devs about it, and am yet to receive a reply. In the mean time, can you guys recommend me something similar? Either online or on IOS, I only have an iPhone at the moment. I'd also prefer it didn't cost too much since I'm most likely only going to be using it until Scrivener is fixed. Thanks, guys.
