TLDR: After receiving multiple warnings that the app would be removed from the Play Store unless updated, I've finally decided to explore Material Design 3 — or Material You, if you prefer — three years after Google introduced that design system. Consequently, I've almost completely rewritten the app. It is free and available for download here: VAT Calculator for Android. You can also enjoy the VAT Calculator for Android video demo.
The whole story
Back in 2012, while I was taking some finance courses, I repeatedly needed to calculate VAT rates. To save my own time and reduce the potential for errors, I developed an
app for that. It was a very simple app that I made primarily for my own use, but I still published it on the Google Play Store (January 21), at that time known as Android Market.
In about 12 years of being publicly available, it has accumulated just above 5K downloads and a 4-star rating. Honestly, I am surprised that it still has about 30 daily active users.
The app had a single AdMob banner ad, and according to the report, it made $87.49 USD. Yep, another golden goose.
The following images show the results of my redesign...
