InterFit Timer is a plan-driven interval training manager built for athletes who need more than a basic countdown. Unlike generic timers that only switch between exercise and rest, InterFit lets you design full workout sequences with named stages—warm-up, work intervals, active recovery, and cooldown—and run them with precise pacing, audio cues, and progress tracking. WHAT MAKES INTERFIT DIFFERENT • Multi-Stage Workout Builder — Design named stage sequences (prepare, exercise, rest, cooldown), not just a single exercise/rest loop. Free users can build up to 3 stages; Pro unlocks up to 30 stages for HIIT circuits, strength supersets, boxing rounds, and yoga flows. • Training Plan System — Save, favorite, duplicate, and reuse structured plans. Browse presets by category (HIIT, Strength, Cardio, Yoga), search your library, and start from the Today tab in one tap. • Stage Timeline Interface — Follow every stage on a clear timeline before and during your workout. The training screen highlights your current stage and auto-scrolls as you progress—no generic single-ring countdown as the core experience. • Live Activities — See your current stage, countdown, and workout progress on the Lock Screen and Dynamic Island. • Apple Health Sync — Optionally save completed interval workouts to the Health app (enable in Settings). Write-only; we do not read your Health data. • Workout History & Streaks — Review weekly volume, streak days, your most-used plan, and filter sessions by day. • Apple Watch Companion — Start recent or favorite plans from your wrist; completed sessions sync back to iPhone. • Focused Training Mode — Full-screen workout UI with pause, skip, and end controls. Voice cues, countdown sounds, and haptics are configurable in Settings. IDEAL FOR • HIIT and Tabata with custom stage design • Strength training rest management • Cardio interval ladders • Yoga and mobility timing • Home and gym sessions where structure matters FREE VS PRO • Free: up to 3 stages per plan, up to 5 custom plans, all core training features • Pro: up to 30 stages, unlimited custom plans, Pro template library, and advanced training insights InterFit Timer helps you train with intention—not just count seconds.
