Mission Outline
Habit Checker was born from a constraint: build a habit tracker in a single afternoon that still felt tactile, personal, and intelligent. The MVP leans into glanceable widgets, streak forecasting, and haptic micro-feedback to keep daily routines on track.
Operational Highlights
- Personalized feedback loops powered by lightweight on-device ML for streak prediction.
- Calendar heatmaps rendered with Metal shaders for butter-smooth performance.
- Offline-first syncing pipeline using CloudKit zones with conflict resolution heuristics.
Learnings
Shipping quickly forced aggressive scope triage and a focus on automation. By pre-building data fixtures and snapshot UI tests, we kept iteration velocity high without sacrificing stability. The approach now informs our ongoing weekly release cadence.
