At this stage we don't have a mobile app and no current plans to build one.
Our website/app can be readily loaded on a mobile device and pinned to your home screen as an app.
However, we have not yet spent much time on mobile responsiveness of the UI since only a small fraction of our customers user it on mobile devices (<10%).
We have it in our roadmap of tasks, particularly to make basic reporting and editing easier. Keep in mind the funnel builder will likely never work well on mobile as its not something we a) expect people to need to use on mobile and b) there are many other things that are likely better recipients of our development effort 😅
