Phase: Cycle Synced Workouts

Your strength isn't random — it rises and falls with your cycle. Phase maps your next 4 weeks and shows your PR windows before they arrive. New: Apple Watch.

Most training plans treat every week the same. Your body doesn't — your strength rises and falls with your cycle. Phase is the strength tracker built around that.

It reads your cycle (from Apple Health or in-app) and adapts your program automatically: push intensity when you're primed, ease volume when you're not — so you stop blaming yourself for "off" weeks that were never your fault.

WHAT A SUBSCRIPTION UNLOCKS • Cycle-aware programming — your plan shifts across menstrual, follicular, ovulatory, and luteal phases. • Power-window predictions — see your likely PR days weeks ahead. • A real strength tracker — plate math, rest timer, e1RM trends, and PRs, color-coded by phase. • The signature chart — watch your strength oscillate with your cycle. Nobody else shows you this. • Apple Watch — run today's session and your rest timer from your wrist. • Private by design — your cycle data stays on your device and in your own iCloud. No servers, no tracking, no ads, no accounts.

SUBSCRIPTION Phase is a subscription app. The features above require an active subscription — an annual or monthly plan, with a free trial available on eligible plans. Prices are shown in the app before you purchase. Payment is charged to your Apple Account at confirmation of purchase (or when a free trial ends), and the subscription renews automatically unless canceled at least 24 hours before the current period ends. Manage or cancel anytime in your Apple Account settings.

Phase is training education, not medical advice. Cycle estimates are for training planning only — never for contraception or family planning.
