DoubleTime is a clean, high-contrast dual-interval timer built for workouts, Pomodoro focus sessions, physical therapy, cooking, and any routine that alternates between two timed phases. Set Timer 1 and Timer 2 once—from 1 second up to 60 minutes—and press Start. When Timer 1 finishes, it plays its own custom alert sound and automatically starts Timer 2. When Timer 2 finishes, it cycles right back to Timer 1—repeating continuously or stopping automatically after your target number of cycles. KEY FEATURES • Dual Alternating Timers: Automatically cycle between Timer 1 and Timer 2 with zero manual restarts. • Second-Level Precision: Set any interval from 0:01 to 60:00 in both portrait and landscape orientations. • Custom Labels & One-Tap Presets: Name each phase ("Work" / "Rest", "Focus" / "Break") or start immediately with built-in presets for Pomodoro (25m/5m), HIIT (45s/15s), 20-20-20 Eye Rest, and Classic 1:1. • Target Cycle Limits & Skip Phase: Run infinite loops or auto-stop after 1–99 cycles, and skip forward to the next phase anytime. • 18 Curated Alert Sounds + Vibration & Silence: Assign distinct bird calls, bells, chimes, vibration-only, or visual-only Silence to each timer so you always know which phase just ended without looking at the screen. • Music-Friendly & Reliable in the Background: Alerts mix cleanly over your music or podcasts without pausing playback, and background notifications preserve each timer's custom label and sound. • Apple Watch App Included: Control timers directly from your wrist with Digital Crown duration pickers, automatic iPhone configuration sync, extended wrist-down runtime, and distinct haptic patterns for each timer. • Privacy First: Zero tracking, zero ads, and no account required.

Verdict

The call

The clearest difference is price: UPRIGHT at Free against DoubleTime Timer's $0.99. UPRIGHT also leads on ratings volume (3.9K vs 3) and iOS requirement (15.1 vs 17.6). DoubleTime Timer's advantage is rating (5.0 vs 4.6) and update cadence (fortnightly vs every 5 weeks). On ads, in-app purchases and device support there is nothing between them.
