I'm working on building Orris (https://apps.apple.com/us/app/orris-breathing-exercises/id67...): a breathing app for iOS. Built it because I wanted something simple for winding down before sleep and everything I tried was either bloated with content I didn't want or locked basic features behind a paywall.
It does guided breathing sessions with variable phase durations (4-7-8, box breathing, etc), streak tracking, and HealthKit integration. It's all based on SwiftUI, Swift 6, with no backend. Currently exploring adding ambient soundscapes for sleep sessions.
Solo project, been working on it for a few months on the side. Also been a fun journey back into iOS after almost 10 years away!
