The Grin Converter app in the Play store is my first attempt at an open source project. I'm using this project to learn about GitHub. Be nice.
Please take a second to rate, and maybe review, the app. This helps the app show up in the rankings.
Grin has been added as an Android app to the Satoshi Bitcoin Converter app in the Google Play store at Satoshi Bitcoin Converter android app. It is suggested that you use the simple Satoshi Bitcoin Converter app, since it (a) does the same as this standalone app, and (b) has multiple other crypto and fiat currencies. If you wish to stick with this app, no problem!
In early 2019, Ignotus Peverell, the founder of Grin, labelled the smallest unit of Grin as a "nanogrin" at gitter.im/grin_community/Lobby (screengrab below). In the Grin Converter app (and Satoshi Bitcoin Converter app), it's marked as an "Igno" as a tip-o'-the-cap to Ignotus. Like a "satoshi" being the smallest unit of Bitcoin, don't you think an "igno" is appropriate for the smallest unit of Grin?
