It took a long time. I think I could have launched about a year sooner, but wanted everything to be perfect, which seems a bit ridiculous now. I think it was the realisation that all the work would sort of be for nothing unless I launched it - that made me actually do it.

The most useful initial feedback was from a reddit group (r/testflight), but friends and family gave very helpful feedback too. I just tried to show anyone I could, it was also very helpful to watch how people use it without guiding them. The most useful feedback will feel brutal initially.

After launch, I did a ShowHN on here, which after posting a few times eventually picked up. Press was tricky initially, but after a lot of persistence, there were a few articles too. I had no idea how much work promoting something would be.
