Thank you all for your kind comments.
We are a small Australian group who made this.
You get 20 free goes when you download it.
Only after that we ask for small $ (buy credits) to help recover our costs to date and pay towards the mining fees. Also if you upgrade to the Pro version, you can use it more too and more features.
We got some awesome feedback to date.The uses are basically endless and a lot of things are better proved in todays world.
Our Android version will be released in a few days. It was actually ready first, but the iOS app kind of overtook it. Just completing testing and it will be on the Google store.
Let us know your favourite uses !
Merry Christmas and Enjoy the App.
