A (very) basic decent start
I'm encouraged that a primarily web service for Slack has created a native app for the iPhone. It's a good start. But to make it an app I can really use it day to day I need boards and timeline views brought to the app (the Premium features I'm paying for) and if you do might as well make an iPad/Mac Catalyst version with an expanded canvas space. Serioulsy, its very hard to find a good Project Management tool that doesn't only run on the browser and integrates with Zapier and Slack, so you're already ahead, close to making it a killer service! Native apps offer better user experience.
