Coherence iOS
I have a soft spot for products that try to change your state, not just capture your attention. Coherence iOS came from that place.
At the surface level, it is a breathing trainer for iPhone: you pick a pattern, start a session, and follow a pulsing orb through inhale and exhale cycles. But what I was really interested in was whether a small piece of software could feel calming without becoming preachy, clinical, or overly ornamental.
So the app leans on rhythm. The orb expands and contracts. Haptics give the breath a physical edge. Pitch-glide tones help the transitions feel smoother. There is a daily streak, configurable patterns, and settings for shaping the practice to your own pace. The goal was not to make meditation content. It was to make a quiet tool that can hold the structure for you while you do the actual breathing.
I like that this project lives in the overlap between interface design and physiology. It is technical — SwiftUI, AVAudioEngine, state management, timing loops — but none of that is really the point. The point is whether the whole thing, taken together, feels gentle and usable enough that you might actually come back to it when your nervous system could use a little help.
That is the kind of software I increasingly care about: tools that are precise, maybe even a little minimal, but still understand that human beings are not just brains tapping screens. We are bodies, rhythms, habits, moods. Coherence iOS is my attempt to build with that in mind.
