Can you get on fediverse, Signup on mastodon.social or any other instance, an official kontalk account it will definitely gonna help. I asked few people for shoutout so interested ios dev can work on kontalk ios app.
You can find other instances here, https://instances.social/ its decentralized socail network filled with people crazy about foss and privacy.
I run one myself its not big but its there https://inditoot.com although i recommend getting on mastodon.social to get better reach.
