Thanks to the person from Milwaukee, WI who recently bought my donation app! To everyone who has supported my Android apps, whether through donations or other app purchases, thank you! It means a lot to know that the work I'm doing is appreciated! https://play.google.com/store/apps/details?id=com.amandafarrell.www.donationfordeveloper_blue

  I made the original app while cashiering at Walmart (I took free Android classes through Udacity.com). I have heard from many people with math disabilities who say it has really helped! This update is to add $100, $50, and $2 for the Canadians out there. Enjoy!

Time for some app stats! My newest app, Time Progress Bars, was released on the Google Play Store in October 2020. Total downloads - 784 Active downloads - 446 Revenue - $12.75 My share of revenue - $8.92 The app has translations for 100+ languages. About half of the downloads are from non-English-speaking countries. I'm not running ads in this app. All revenue is from an in-app purchase that lets users change the color scheme.

I receive a lot of reviews of scorekeeper asking for the ability to edit the names of players, which is a feature already available through long-pressing on the player name. Apparently, long-pressing is not something intuitive to try for some people, so they are left without the ability to change the player name. I hope this video preview helps make it easier for users to understand how the app works and how to get to additional features already available to them.

This is my first published app built with Kotlin! :) Features: Use volume buttons to keep score for two teams Can reset to any scores you choose Available in 100 languages Code on GitHub .

This app got 25 downloads and a five-star review in its first week on the Google Play Store! Code on GitHub

I made a python tool (which uses selenium and chromedriver) that takes in a phrase to translate and an array of language codes of the languages you want to translate the phrase into. It creates google translate URLs, copies the translations into an array, and then prints the array (which I then use to copy into Android Studio's translation tool). Here's a link to the python code for anyone interested:  https://github.com/amandafarrell/PythonTranslationsTool/blob/master/Translations.py Most of my app downloads are not in English (for example, my Scorekeeper app has been downloaded over 20,000 times and less than half of those downloads are in English), so it was worth it to me to manually create translated versions of my apps, but going forward I wanted to do less copying/pasting. Hopefully, this tool is helpful to others as well!

My Scorekeeper download stats show a consistent spike every Saturday, and big spikes around Christmas and New Year's. I wouldn't have predicted it, but it totally makes sense that people would play more games on weekends and holidays. 

A quick overview of uploading to the Google Play Store. This is as of December 2018. Some things have changed since I uploaded my first app in July 2017, but overall the process is still very similar.  Even though things will probably change a bit if you are watching this months in the future, I thought it would be worth it to make a quick video.

This is a quick tour of how the SQLite database in my simple scorekeeper app is set up.

This is a 3-minutes video about how to make a simple counter app in Android Studio. I recommend using your own Android phone if you want to try it out, though you can also use the emulators that come with Android Studio if you don't mind waiting patiently while they load.
