Interesting. Whenever I talk about Quality, the downvotes appear. It's almost as if people are actively against the concept of high-Quality software.
This is not some idle boasting. This is a project with a great deal of history.
Here's the app, itself, in the App Store: https://apps.apple.com/us/app/ambiamara/id1448933389
It started off as "SpeakerBeeper," in ObjC, ten years ago. Here's the codebase for that: https://github.com/LittleGreenViper/speakerbeeper
It then became "X-Timer," in 2015-17, after Swift came out. Here's the codebase for that: https://github.com/LittleGreenViper/x-timer
This is the current codebase for the "AmbiaMara" app, which has been out for the last three years or so: https://github.com/RiftValleySoftware/ambiamara
The codebases show a lot of learning and growth. You can easily see how fast I work, and how I'm able to maintain a fairly high level of Quality, throughout the project.
Yeah, it's just a silly timer, but it's a good one. I use it constantly. I basically wrote it for myself. A lot of my work is like that.
