"Yeah. Only Android right now. Not sure if it's Apple's fault or Coinomi's for not being on there.
as for proposals and voting, it was paused for past few months due to a code issue and rebranding. It will be re-enabled as early as next month.
once the budget system is back up, you can make proposals. Not sure if we'll have a dedicated front-end web portal for it immediately. if not, we'll have to use our
forum.pivx.org where you post the proposal and then submit it via debug CLI in your wallet pointing to your proposal URL. voting will be done by masternodes. (also through the debug CLI I would assume)"
