InterFit Timer
Read full descriptionHide full description
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. InterFit Pro is an auto-renewing yearly subscription ($19.99/year). Payment is charged to your Apple ID account upon confirmation. Subscription automatically renews unless cancelled at least 24 hours before the end of the current period. Manage or cancel your subscription in your Apple ID Account Settings at any time.

Verdict
The clearest difference is in-app purchases: InterFit Timer at none against ICAROS's 4. ICAROS's advantage is update cadence (every 3 weeks vs every 17 months) and iOS requirement (15.6 vs 17.0). On price, ads and device support there is nothing between them.
