This app isn't a standalone app. This unlocks all the features of Material Icon Maker. You should install the app before using this key. Install from https://play.google.com/store/apps/details?i=com.arunsoft.icon

This unlocks the following features:
* Unlocks all shapes including Squircle, Pentagon, Hexagon, Octagon and Decagon.
* Customize the round radius
* Export to hi-res upto 512 x 512.
* Export to all resolutions automatically for android launcher icon (for developers).
* Export adaptive icons for android apps.
* Use more cool fonts.

If you choose to buy, I greatly appreciate that. It helps me continue development.
Feel free to submit your feedback or suggest improvements by contacting me with the link in the app.
