Volt Coach engaged us to ship a companion app alongside their instructor-led programmes—calendar-aware workouts, progress capture, and tiered subscriptions surfaced cleanly for trial users upgrading mid-cycle.

The mobile client emphasises resilient offline caches for gym-floor usage, HealthKit / Health Connect hooks where permitted, and push-driven reminders tied to coach schedules. Release cadence included phased rollout, staged feature flags, and crash prioritisation from production telemetry.
