Cycling Zone Calculator

Anyone who knows me, knows that sports are one of my others passions out side of technology. One of those sports is cycling.  Back in 2013 when I was trying to figure out the basics of development using Obj-C for iPhone, I had decided to build a simple application that allowed me to calculate my FTP for on bike training.  For those that don't know FTP stands for Functional Threshold Power and is a measurement that is used when training using watts in cycling.

Fast forward to 2021.  I received an email form Apple saying they were going to remove my app from the store due to lack of updates in the past years.  So, I decided to take an evening and re-write the application so that it could be re-submitted.

For this project, I chose to use React Native as it would allow me to quickly develop the application using JavaScript so that I could get it back in the store, as there was still a handful of users that had it installed on their phones. On top of that, once I have some time to go back and revisit the UI, I would be able to publish it as an app both on the Play Store targeting Android as well as on the iOS app store.

If anyone is interested in taking a look at the source code it is available on GitHub.
