I launched the iOS version of Mind Mapping 3D on Product Hunt. It did OK, but I wish I had better cultivated an audience before launching.
I decided to launch an iOS version to broaden the net and capture more users. This also makes me feel freer to engage users. Now no one will say "that doesn't' work on my phone" because I also have the android version.
Mind Mapping 3D first launched on Android in February of 2018. To date, it has been installed 10K+ times and is retained by about 30% of users long-term. Despite the user count being good, my conversion rate is low. Improving that will be my focus.
