This semester I had a group project that required us to build a software product. My group decided to make an iOS fitness app and I handled the workout tracker. I still have a few weeks left but I’m pretty happy with where it’s at so far. 1/2

I made Quit Clock as my first app to learn iOS development and to track my personal sobriety. I know the space is crazy saturated and the app is pretty simple so I’m blown away when anyone other than my mom downloads it! 1/2

My first app, Quit Clock: Kick Bad Habits, is now in the App Store for all iOS 26 users! I spent a long time bouncing from one tutorial to another before deciding I just needed to make something and stick it through.

Took some time over the last two days to work on my iOS app QuitClock. I finally have it in a place where I feel ready enough to submit to the App Store. Curious how the process will go and whether or not I missed anything. #buildinpublic #iosdev

Added quite a bit to the app over the last few days. Ability to reset the quit date to the current date. A detail view that shows days, weeks, months, and years since quitting. And alerts to confirm before deleting or resetting. #buildinpublic #iosdev

I added sorting to my app today. Debating whether to add more before submitting or keep v1.0 simple. #buildinpublic #iosdev

Over the last month or so I’ve been building my first iOS app using SwiftUI. Now that I finally have a developer account, it is on my phone for testing! #buildinpublic

20 out of #100DaysOfSwift complete. For the Day 19 challenge I made a Volume Conversion app. Still a lot to wrap my head around, but pretty stoked that I finished the thing.
