Symbiance

For engineers who want data, not guilt. Set personal SLOs for sleep, focus, and balance. Your Friday Refactor is written on-device by Apple Intelligence.

Symbiance helps engineers, founders, and technical leads protect their focus, sleep, and balance by treating personal limits the same way they treat production systems — with objectives, budgets, and blameless reviews.

Define SLOs for sleep, exercise, mindful minutes, offline-by-cutoff, and deep-work blocks. Each off-day burns your weekly error budget. When the budget runs out, the SLO has breached — a signal to learn from, never a reason for blame.

On Fridays, Symbiance uses Apple Intelligence to generate your weekly Refactor: a blameless, data-grounded review written entirely on-device. Your data never leaves your phone.

• Budget tracking with burn strip • Daily check-in for non-HealthKit signals • HealthKit integration (sleep, exercise, mindfulness) • Weekly Refactor — on-device AI, fully private • Streaks and wins surfaced alongside breaches

Refactor requires Apple Intelligence (iPhone 15 Pro or later). All other features work on any iPhone running iOS 18.
